Basic Operations

Carefully remove all items from the package and follow the step-by-step operation instructions below.
The main screen will display all sensors connected to the tablet with a color- coordinating ring and CO2 reading. The sensors are initially ordered by which sensors were connected first. The sensors are updated every two seconds with the most recent CO2 concentration, Relative Humidity, and Barometric Pressure. The CO2 Reading is compensated by the ambient Barometric Pressure. The order of the displayed sensors can be user-configurable under the “Sensor Properties Screen”.The image above is your main display screen. This screen will show all the sensors configured – up to 12 currently with strobes – and their accompanying CO2 levels. We have two displayed here, which is what is included in the purchases of 1 CM-7000 CO2 Multi-Sensor System. You notice a gear icon in the upper right-hand corner of the screen. This will open your settings screen. From the settings screen, you will also have the ability to lock/ unlock the device with the CO2Meter password and change the audio, strobes, sensors, and relay configurations.
The main display screen will also display the sensor color-coordinating ring dependent upon the given CO2 Reading, as well as the other sensor readings including Relative Humidity and Barometric Pressure.
The sensor readings will continue to be updated as the sensor properties screen is open. It also contains editable properties of the sensor including the Location Name, Zone, and Position on the main display. The user is also able to mute the sensor if it is in alarm, and can reset the sensor if it is in an alarm state that is latched.

Settings Menu

The settings menu allows the user to adjust the alarm settings.
There are four alarms that can be set with the following properties:

• Alarm Levels
  The CM-7000 CO2 Multi-Sensor System features four alarms, Alarms 1-4 with the default set at AL1 5,000ppm TWA, AL2 5,000ppm, AL3 1.5%, and AL4 3%. All of these are user-configurable from the settings menu.
  This means that you have four levels of alarm that can all trigger different functionalities. The first setting under Alarms one through 4 is AL1 – Alarm 1 defaults to 5,000 ppm TWA. This is the OSHA standard for first-level alarms. As you read left-to-right, you can alter these to different levels.

When the device senses too much CO2 it begins to alert the user in three ways (if so configured):

1. Audible horns will sound and the tablet will verbally detail the alarm notification.
2. The visual indication will come from strobes and a visual indication on the tablet of the sensor and its status.
3. Statuses may be GREEN, YELLOW, AMBER, or RED depending on the severity of the gas leak Audio

The audio switch will determine if the Horn connected to the sensor should be triggered

• Strobe
  The strobe switch will determine if the Strobe connected to the sensor should be triggered. You can turn the strobes on or off for reach alarm setting depending on your application or environment needs/requirements.

• In addition, you will find that in the system settings screen, the horn strobes can be individually tested per associated individual sensor by selecting from the sensor drop-down setting underneath the latch and choosing “All” instead of “Individual” functionality dependent upon the specific sensor and AL1-AL4 alarms.

Relay 1
The relay 1 switch will determine if the Relay on the Tablet or on the Remote Relay Unit will be switched to the ON position. This means for whichever alarm setting it is turned on for, whether it’s Alarm 1,2,3, or 4, Relay 1 will activate. The same thing goes for Relays 2 and 3.
Please note Relays are not tested with the test button, individuals will need to scroll down to the bottom of the settings screen under “Tablet Relay Non-Alarm State” to individually select “Active” or “Inactive” to set no NC pathway.

• Relay 2
  The relay 2 switch will determine if the Relay on the Tablet or on the Remote Relay Unit will be switched to the ON position

• Relay 3
  The relay 3 switch will determine if the Relay on the Tablet or on the Remote Relay Unit will be switched to the ON position

• Latch
  The latch switch will force the alarm to stay on, even if the sensor reads below the alarm trigger level.
  This functionality was designed specifically for Denver, CO, and is a key- driven shut-off box to mute the alarm until the fire marshal can evaluate the situation.

• Sensors
  The sensors drop-down allows the user to choose if only the sensor that is triggered will alarm, or if all sensors connected to the tablet will alarm.

• Mute
  The mute drop-down allows the user to choose what is muted. Choices are Horn Only, Strobe Only, Both Horn and Strobe, Relays Only, or all. This function will silence the alarm for the user’s configured amount of time.
  Default mute time is set to 30 seconds.

• Mute Time
  The mute time dropdown allows the user to choose how long the mute will last. Choices are 15 seconds, 30 seconds, or 60 seconds.

• Password Protected
  Please note that the device does come password protected. This is a great feature if you are a manager or industry professional. This allows only those with the password to make adjustments to the device. The password is fixed, and cannot be changed.

To make edits to the name of the sensor, first tap the lock icon in the upper right-hand corner, type the password “co2meter”, and hit unlock. The lock icon in the right-hand corner will then indicate an open lock.
Now that the device is unlocked, you can name the sensor from this screen. Tap “Give Location Name” and rename the sensor to something that allows you to understand where the sensor is located. Once you have finished renaming the sensor, tap the small “down” arrow below the keyboard.
Once you are done on the sensor dashboard hit “done” in the upper left-hand corner.

Calibration

It is good practice to regularly calibrate the CO2 Sensor. We do so by Zero Calibrating using pure 100% Dry Nitrogen.
The procedure is as follows:

1. On the tablet, tap on the sensor you are calibrating. Tap on the Unlock Button on the top right and enter the password. Scroll to the bottom of the sensor properties screen and tap the “Calibrate” button.
2. Place a flex tube connected to a tank of 99.9% Dry Nitrogen to the sensor orifice on the Remote Sensor Unit
3. When the sensor reads below 300ppm, the calibration will begin and takes 1 minute
4. Leave the flex tube of Nitrogen on the sensor orifice for the entire minute
5. When calibration is complete, the Red Alarm LED on the Remote Sensor Unit will flash 5 times, the Strobe may flash as well.
6. Check the tablet for a message validating that the calibration was succe ssful.
7. If the unit fails calibration, it will state fail and you will need to keep the sensor main screen open and troubleshoot, via contacting our support team at either support@CO2Meter.com or speak to an expert, 877-678-4259.

Please note: The end user has a choice of either calibrating themselves with a tank of nitrogen, or sending it back to CO2Meter to calibrate for a small calibration fee.
