Any rapid up-scale reading, followed by a declining or erratic reading, may indicate a gas concentration beyond the upper scale limit which may be hazardous.
Strong Electromagnetic Interference (EMI) may cause incorrect operations.
Only the combustible gas detection portion of this instrument has been assessed for performance by CSA International.

READ FIRST BEFORE OPERATION
Gas Clip Technologies (GCT) Multi Gas Clip (MGC) detectors are personal safety devices designed to detect the presence of specific toxic gases: carbon monoxide (CO),  hydrogen sulfide (H₂S), oxygen (O₂), and combustible gases/Lower Explosive Limit (LEL). Before the operation, ensure that you have been properly trained on the use of the
equipment and the appropriate actions to take in the event of an alarm condition.

DETECTOR COMPONENTS

BASIC OPERATION

Button Usage
The following operations are driven by a single power/menu button located on the front of the instrument:

• Turning detector ON/OFF
• Menu navigation (Status and Options)
• Bump testing
• Calibration
• Latched alarm acknowledgment
• Backlight activation

Turning On the Detector
To activate the detector, press and briefly hold down the power/menu button. If the battery is too low for activation, the detector will display “LOW BAT” and then turn off again. Once activated, the detector will begin to display gas readings immediately. Each sensor will show a chasing “0” for the sensor reading while it is stabilizing and being self-tested. The display will show:

Once all sensors have completed the warm-up and stabilization sequence (< 65 seconds), the detector is ready to detect all applicable gases.
Turning Off the Detector
Press and hold down the power/menu button through the shutdown sequence. The LCD will display “OFF” along with a countdown as shown here:

During the countdown, the detector will beep and flash 4 times. Release the button after the countdown and the detector will turn off.

DISPLAY COMPONENTS

Display Layout

Display Details
When a particular gas has a Gas Reading (4) at, or above, its alarm thresholds, the Gas Identifier (5) icon will flash and the associated Alarm Condition (1) icon will display.
During a calibration or bump test, the Calibration/Test Mode (2) icon will display when it is time to apply gas.
The Battery Charge Level (3) is displayed in a 3 bar battery icon as well as a percentage. The percentage calculation is approximate and can be used to provide a rough estimation of the time remaining before recharging.
Warning: Users must familiarize themselves with the icons in both non- alarm and alarm states.
Warning: If the display is missing icons, or cannot be clearly read, discontinue use and contact GCT.
Warning: The IR LEL sensor will not detect hydrogen (H₂) or acetylene (C₂H₂) gases; however, due to their cross-sensitive nature, the CO sensor will go into alarm well below 10% LEL.

ALARMS

Default Alarms
Each detector comes preprogrammed with the following factory default alarms for LOW, HIGH, Time Weighted Average (TWA) and Short Term Exposure Limit (STEL):

   Link, MGC Dock, or MGC Wall Mount Dock.

3. User Message – A unique programmed message, up to 36 alpha-numeric characters, can be assigned to individual detectors (refer to the Adjustable Options section). If the User Message does not fit on one screen, it will scroll right-to-left twice. If no User Message is set up, the detector will skip ahead to the Sub-Menu Prompts: “SHOW STATUS” & “SHOW OPTION”. The Default user message is “GAS CLIP TECHNOLOGIES”.

4. Sub-Menu Prompts – Pressing the power/menu button briefly during a Sub-Menu prompt, “SHOW STATUS” (to access the Status Menu) or “SHOW OPTION” (to access the Options Menu), will cause the detector to show more information for that Sub Menu. If the power/menu button is not pressed, the detector will immediately return to normal operation.

Status Menu

The Status Menu is accessed by pressing the power/menu button once during the “SHOW STATUS” prompt. The detector will display in the following order:

1. CAL”- the last calibration date
2. “CAL DUE” or”CAL IN “- denotes if calibration is due or how many days until it is due
3. “L. BUMP”- the last bump test date
4. “BUMP DUE” or”BUMP ” – denotes if a bump test is due or how many days until it is due (will be displayed only if a bump test interval has been set up)
5. ‘TWA” – current Time Weighted Average readings.
6. “STEL” – current Short Term Exposure Limit readings.
7. “HIGH “ – peak sensor readings.
8. “CLEAR ALL” prompt – press the power/menu button once during the “CLEAR ALL” prompt to clear the TWA, STEL, and Peak sensor readings.

Calibration Information -The date of the last calibration, along with the number of days remaining until the next calibration is due, will be displayed. If calibration is due, the detector must be calibrated (refer to the Calibration section).
Bump Test Information -The date of the last bump test, along with the number of days remaining until the bump test is due, will be displayed. If a bump test is due, the detector must be bump tested (refer to the Bump Testing section).
Peak Levels -The detector will display the current TWA and STEL readings, followed by the peak concentrations recorded for each sensor. Each time the unit is turned off these values will be reset.
Clear Peak Levels – Pressing the power/menu button during the “CLEAR ALL” prompt will cause the TWA, STEL, and peak concentrations to be cleared. Note: this does not remove the information from the internal memory logs of the detector.

Option Menu

The Options Menu is accessed by pressing the power/menu button once during the “SHOW OPTION” prompt. The detector will display in the following order:

1. FW VER”— denotes the detector’s current firmware version
2. TWA alarm limits
3. STEL alarm limits

5. HIGH alarm limits

Firmware Version – The current firmware version that is on the detector will be displayed. Notifications of the most recent firmware versions can be found on the Resources page of the GCT website at www.gascliptech.com.

Alarm Set Points -The current alarm limits for TWA, STEL, LOW and HIGH will be displayed in sequence.
Adjustable Options
The detector’s options can be configured using the GCT IR Link, MGC Dock, or MGC Wall Mount Dock.
User Message – An optional, user-programmable, text message can be used to show company branding, a unit identifier, or any other pertinent information. The User Message will be displayed right after the date and time each time the Main Menu is accessed.
Alarm Limits – Each sensor contains separate alarm threshold values that tell the detector when to go into alarm. Alarm limits may be disabled by setting them to zero.

Caution: Confirm alarm levels with local laws/regulations before operation.
SAFE Display – “SAFE” will be displayed if there are no gas or instrument alerts.
Self-test Lock – When a sensor self-test fails, the detector shows “Err” on the display and goes into high alarm. The self-test lock option specifies whether a power/menu button press can silence the alarm.
Off Lock – Prevents the detector from being deactivated by a power/menu button press. If Off Lock is enabled, only a low battery, MGC Dock, or MGC Wall Mount Dock can deactivate the detector. Holding the power/menu button down will initiate Manual Calibration mode.
Maintenance Notification – If maintenance notification is enabled, the detector will periodically flash the maintenance LED when a bump test or calibration is due. Otherwise, if the option is disabled, the detector will only show the maintenance text on the display.
Dock Lock – Dock Lock prevents bump tests and calibrations without the use of the GCT IR Link, MGC Dock, or MGC Wall Mount Dock.
Latching Alarms – Latched alarms will hold the detector and its display in its peak alarm condition until the power/menu button is pressed.
Auto-Zero – The detector can optionally zero the sensors with every power-up.
TWA Method – The algorithm used to calculate the TWA can be set to either an average over a moving window (OSHA) or as a cumulative average (ACGIH).
TWA Interval – The TWA interval defines the timeframe over which the long-term average is calculated. Default is 8 hours.
STEL Interval – The STEL interval defines the timeframe over which the short- term average is calculated. Default is 15 minutes.
Sensor Enable/Disable – Individual sensors can be disabled. A disabled sensor is completely removed from the detector’s display for sensor readings, alarm limits, and calibrations.
Caution: A disabled sensor will not measure gas or detect alarm conditions.

Bump Interval – The bump interval controls how often the detector notifies the user to bump test the sensors. The interval can be individually adjusted for each sensor from 1 to 365 days. Default is 0 days (disabled).
Calibration Interval – The calibration interval controls how often the detector notifies the user to calibrate the sensors. The interval can be individually adjusted for each sensor from 1 to 365 days (default is 365 days) except for the pellistor sensor which can be adjusted from 1-180 days (default is 180 days).
Calibration Gas – When the detector is calibrated, it scales the sensor readings to match the concentrations of the applied gases. The calibration gas concentrations can be adjusted to match the respective levels contained within the gas bottle. Default is: 25ppm H2S, 100ppm CO, 18% O2 and 50% LEL (2.5% vol CH4). %-by-Volume CH4 – Allows the detector to display gas readings as %-by- volume CH4 rather than % LEL. The conversion rate can be configured by specifying what the methane concentration is for 50% LEL (typically 2.5% in North America and 2.2% in Europe).
Language – The detector will display all its text prompts in any of six languages: English, German, French, Spanish,
Italian or Portuguese.
Note: OL, Err, and sensor icons remain the same for all languages.
Activity LED Period – This option periodically flashes a single LED on the detector at a rate specified by the user to indicate that the detector is on. The time between flashes can be set and adjusted through the GCT IR Link software or GCT Manager software. The minimum time between flashes is 5 seconds, maximum is 120 seconds. To enable this function using the GCT Manager software, click the checkbox next to Activity LED Period then set the period to the number of seconds desired between flashes. To disable this function, uncheck the checkbox next to Activity LED Period and set the period value to “Off”. NOTE: Simply unchecking the checkbox next to Activity LED Period without setting the period to “Off” is not sufficient to disable this function on the detector. To enable/disable this function using the GCT IR Link software, the procedure is the same without the checkbox. Last, click the “Write” button at the bottom on the GCT IR Link software or GCT Manager software for any changes to take
effect on the detector.
MSHA Mode – This option is only available with Multi Gas Clip IR detectors that have the MSHA logo on the back of the detector. Once enabled, MSHA Mode will force the detector to display the LEL in % volume CH4. MSHA Mode can be turned on and off using the GCT IR Link software or GCT Manager software. After turning MSHA Mode on the detector will request a calibration. This notification will persist until calibration is successfully completed. Simply turning MSHA Mode off will not remove the request for calibration.
NOTE: MSHA Mode calibration takes twice the time as a normal calibration. MSHA Mode is not available on pellistor detectors.

DETECTOR MAINTENANCE

Bump Testing
The detector can be configured to keep track of regular bump testing intervals in a Bump Log. The interval can be individually adjusted for each sensor from 1 to 365 days, default is 0 (disabled). When a programmed bump test comes due, or if the last bump test has failed, then the detector’s display will continually flash “BUMP DUE” until the detector has been successfully bumping tested. If the detector is turned off, the “BUMP DUE” prompt will reappear again once the detector is reactivated and continue until a bump test is successfully completed. Performing a bump test that will be recorded in the Bump Log can be done either automatically: insert the detector into the MGC Dock or MGC Wall Mount Dock, or manually: apply gas according to the Manual   Bump Test Instructions are described below.

Manual Bump Test Instructions
Press the power/menu button two separate times in quick succession (double- tap) to access the Main Menu. The display will then show, in the following order:

1. Current Date/Time – “DD”, “MON” & “TT: TT” below stand for Day, Month & Time
2. User-Programmed Text Message
3. “SHOW STATUS” Prompt – When the screen displays “SHOW STATUS”, quickly press and release the power/menu button to display the current calibration status followed by the current bump test status.

Press the power/menu button

The next step depends on the following situations:

• When a bump interval has been programmed into the detector and a bump test is due , the current bump test status will show: “ L . BUMP ___” (the date of the last bump test) followed by “BUMP DUE”. Audible, visual & vibrating prompting to apply gas will automatically start. The display will alternate between “BUMP DUE” and “APPLY GAS”. Snap the MGC Calibration Cap (provided with the detector) into place over the sensor ports. Apply gas to the detector at a flow rate of 0.25 to 0.5 LPM  and do not disturb while the test is being performed. Once all of the sensors have been tested, the detector will go into alarm. Remove the MGC Calibration Cap and the detector will return to normal operation after a short period of time. The bump due date will be automatically reset. The bump test will be recorded in the Bump Log.

• When a bump interval has been programmed into the detector, but a bump test is not yet due,
  the current bump test status will show: “ L . BUMP ” (the date of the last bump test) followed by **“BUMP d.” (the number of days until the next scheduled bump test is due). Quickly press the power/menu button while the display shows “ BUMP ___d.” to force a manual bump test. Audible, visual & vibrating prompting to apply gas will start. The display will alternate between “ BUMP DUE ” and “APPLY GAS”.** Snap the MGC Calibration Cap (provided with the detector) into place over the sensor ports. Apply gas to the detector at a flow rate of 0.25 to 0.5 LPM and do not disturb while the test is being performed. Once all of the sensors have been tested, the detector will go into alarm. Remove the MGC Calibration Cap and the detector will return to normal operation after a short period of time. The bump due date will be automatically reset based on the new bump date. The bump test will be recorded in the Bump Log.

Press the power/menu button

• When a bump test interval has not been programmed into the detector , the current bump test status will show: “ L . BUMP ” (the date of the last bump test). Quickly press the power/menu button while the display shows “ L . BUMP ” to force a manual bump test. Audible, visual & vibrating prompting to apply gas will start. The display will alternate between “ BUMP XXXd.” and “ APPLY GAS ”. Snap the MGC Calibration Cap (provided with the detector) into place over the sensor ports. Apply gas to the detector at a flow rate of 0.25 to 0.5 LPM and do not disturb while the test is being performed. Once all of the sensors have been tested, the detector will go into alarm. Remove the MGC Calibration Cap and the detector will return to normal operation after a short period of time. The bump test will be recorded in the Bump Log.

Press power/menu button

• When a bump test has failed , the current bump test status will show: “ L . BUMP FAILED ” (indicating that the last bump test had failed). Audible, visual & vibrating prompting to apply gas will automatically start. The display will alternate between “BUMP DUE” and “APPLY GAS”. Snap the MGC Calibration Cap(provided with the detector) into place over the sensor ports. Apply gas to the detector at a flow rate of 0.25 to 0.5 LPM and do not disturb while test is being performed. Once all of the sensors have been tested, the detector will go into alarm. Remove the MGC Calibration Cap and the detector will return to normal operation after a short period of time. The bump test will be recorded in the Bump Log.

If a sensor fails the bump test, the display will show “Err” and designate which sensor did not pass. The failed sensor will be disabled and will need to be replaced (see “Err” in Failures/FAQ’s section).

• During a manual bump test, the audible, visual & vibrating prompting to apply gas will continue for approximately two minutes. If gas is not applied within two minutes, then the bump test will automatically fail. The prompts will cease, the detector will return to normal operation, but the display will continually flash “BUMP DUE” until the detector has been successfully bumping tested. Please note, to abort a bump test at any time, press the power/menu button once and the detector will return to normal operation.

Note – Users may simply apply gas to the detector at any time during normal operation to run a bump test without going through the steps above. Be aware, this will not be recognized by the detector as a Manual Bump Test therefore it will be recorded into the Event Log as an Event, not into the Bump Log as a Bump Test.

Calibration
The detector can be configured to keep track of regular calibration intervals in a Calibration Log. The interval can be individually adjusted for each sensor from 1 to 365 days (default is 365 days) except for the pellistor sensor which can be adjusted from 1-180 days (default is 180 days). When a calibration comes due, or if the last calibration has failed, then the detector’s display will continually flash “CAL DUE” until the detector has been successfully calibrated. If the detector is turned off, the “CAL DUE” prompt will reappear again once the detector is reactivated and continue until calibration is performed. Performing a calibration that will be recorded in the Calibration Log can be done either automatically: insert the detector into the MGC Dock or MGC Wall Mount Dock, or manually: apply gas according to the Manual Calibration Instructions described
below.

Manual Calibration Instructions
To enter the Manual Calibration mode, continuously hold down the power/menu button through the shutdown sequence (see Turning Off the Detector section) and the calibration countdown sequence that follows it. Display will show:

During these two countdowns, the detector will beep and flash 8 times with a pause between countdowns. Release the button after both countdowns are complete. The detector will first automatically zero the sensors at the current baseline reading, then the “APPLY GAS” prompt will appear. Display will show:

Once the screen displays “APPLY GAS”, snap the MGC Calibration Cap (provided with the detector) into place over the sensor ports. Apply gas to the detector at a flow rate of 0.25 to 0.5 LPM and do not disturb while calibration is being performed. Sensor readings will be displayed as the gas is detected and as the detector adjusts the calibration parameters. Once calibration is complete, the detector will display the next calibration date before returning to normal (alarming) operation. If a sensor fails to calibrate, the detector will display “Err” – an error message for the failed sensor. Check your gas connections and concentration before attempting a second calibration. If a sensor fails to calibrate after a second attempt, contact GCT for assistance.

Battery
The battery is displayed as both a percentage and a 3-bar Battery Charge Level icon. The percentage calculation is approximate and can be used to provide a rough estimation of the time remaining.
When the detector determines that only 20 minutes of run time remains, it will beep, flash, and display “LOW BAT” on the screen. This will repeat with 10 minutes remaining, and then continuously for the last 5 minutes of run time. When the battery has expired, the detector will give 5 long beeps and flashes, display “OFF” and then shut down.

To charge the detector, either plug it into an AC outlet using the provided charging adapter or charge using an MGC Vehicle Charger, MGC Charging Station, or MGC Multi-Charger (all authorized GCT Multi Gas Clip Optional Accessories). The detector will cycle the battery icons in a charging fashion until the battery is fully charged. It is advisable to turn the detector off before charging.

DO NOT charge the instrument in a combustible atmosphere.
DO NOT charge the instrument in temperatures above or below the specified range of 0°C to 40°C.
DO NOT substitute any other battery type than specified and supplied by GCT.
DO NOT use any charger other than that supplied or offered by GCT.

Storage
Store the detector in a safe, dry place between 32°F and 77°F (0°C – 25°C). For longer storage, the detector battery should be discharged to about 40%. After storage, charge the battery and verify the detector calibration before use.

****Review the warranty period and the “Activate before…” date that is printed on the product box label.

DETECTOR RECORDS (LOGS)

During operation, the detector automatically records all user activity. These records can be downloaded from the detector using the GCT IR Link, MGC Dock, or MGC Wall Mount Dock. The Event, Bump and Calibration Logs are always downloaded. Partial data logs may be downloaded in order to reduce the transfer time. Partial data logs contain approximately 1 week of data. New data log downloads will only contain the data since the last download. Full log downloads contain the entire data log, typically at least 2
months’ worth of data.

Event Log
The detector stores the last 25 alarm events. These are organized by first-in, first-out (FIFO) so the 26th event will replace the first event and so on. The detector records the specific alarm conditions for each event as follows:

• Date and time at the start of the event
• Duration of the alarm condition
• Each sensor’s peak alarm status and reading

Bump Log
The detector stores the last 25 bump tests. These are organized by first-in, first-out (FIFO) so the 26th bump test will replace the first bump test and so on. Bump tests are differentiated from normal events when the alarm condition occurs inside of an MGC Dock or MGC Wall Mount Dock, or when the detector is manually bump tested according to the Bump Testing section. The detector records the bump status for each test as follows:

• Date and time of bump test
• If the bump test was performed manually or with the MGC Dock/Wall Mount Dock
• Each sensor’s peak alarm status and reading
• The result of each sensor’s bump test

Calibration Log
The detector records the last 25 calibration attempts. These are organized by first-in, first-out (FIFO) so the 26th calibration will replace the first calibration and so on. Each calibration attempt will be recorded as follows:

• Date and time of calibration
• If the calibration was performed manually or with the MGC Dock/Wall Mount Dock
• Each sensor’s gas concentration calibrated to
• Each sensor’s calibration success status

Data Logs
The detector records its current operational status every second. The logging interval cannot be adjusted, but the Detect compresses the data to reduce the storage and transfer times of redundant records. The typical logging capacity is at least 2 months of data. The following items are recorded into the log:

• Date and time
• Sensor readings and status conditions
• All user and sensor options
• Events (i.e. turn on or off)
