INTRODUCTION

You have purchased the FD-311 INDUSTRIAL GAS DETECTOR by FORENSICS DETECTORSTM . The detector is factory calibrated, TURN ON AND GO! This product is an INDUSTRIAL gas analyzer made with a robust ABS design using a high-quality thermal conductivity sensor. This detector is made for industrial use for engineering professionals, technicians, contractors, energy inspectors, researchers, and labs.

QUICK SETUP

Ensure all components are included.
Ensure analyzer is fully charged. If not, please charge the battery first.
Double check all tubing is well connected and in place. Check all connections.
Turn ON the detector. After countdown and self-check the pump turns ON and READY to use when the instantaneous gas concentration is shown.
Start measuring. Real-time measurements are shown on the HOME screen.
Read this manual and familiarize yourself with the operation.
Always be safe.
Before turning OFF, flush/purge the air out the detector by allowing the pump to run for 60 secs to allow fresh air to purge the instrument.
Ensure tubing and items are clean before storing as to avoid any contamination, residual odors or toxic gases that may poison the sensor.

ANALYZER OPERATION

ON/OFF: Press MIDDLE button for 3 seconds. After 60 sec countdown gas detection begins, pump is ON and real time detected gas levels is show on the HOME SCREEN. The home screen displays Time, Fan Icon, Battery Level Icon, Gas and Gas Concentration. You will hear the pump and you are ready to start taking measurements. To turn OFF, press MIDDLE button for 3 secs. Press the left button to Turn off/on the PUMP. Press the right button to Mute. When in normal operation, the Home Screen will appear like below on the left image.

MENU: Press the MIDDLE button. Enter the passcode 1111. Use the arrowsand middle buttons. Then you will enter the MENU SCREEN. The menu screen is shown below right. Use LEFT and RIGHT buttons to make your selection, press MIDDLE button to select.

MENU SCREEN

ALARM SETTINGS

AlarmSet: Alarms are triggered (LED flashes, Buzzer and Vibration) when alarms points are met/exceeded. To change the alarm set points select AlarmSet in the Main Menu (see prior section). You can change the preset alarm level to your desired level by using the left and right buttons.

ALARM SET

NOTE: If ALARM triggers are critical to your application, always check the alarm setting to ensure you are protected and alarm settings are as you anticipate to avoid harmful exposure levels.

ALARM LOGGING

AlarmLog: When alarms are triggered they are automatically recorded with a date and time stamp along with the (min or max) alarm data point. This is useful for safety personnel to keep track of exposures for record keeping and exposure analysis purposes.

ALARM RECORD LIST (Example)

ZERO CALIBRATION

ZeroSet: ZeroSet should not be used very often – only if for some reason the baseline zero value of the sensor value is flickering or drifting and does not maintain a zero value.
Select ZeroSet from the Main Menu Screen. Expose to ZERO air for 1 min. Usefresh air. Maintain a flow of > 0.5L/min to deliver the gas to the detector (i.e. via the inlet). Use a T-piece. Excess gas should exit from the free parth (see our YouTube video on calibration for Model FD-311). Then press SAVE button to confirm the zero value. The value next to the zero value should be ignored (it is an internal technical value). Then press Save – when complete, a blue floppy disk icon will appear.

Gas Zero

SPAN CALIBRATION (see our YouTube Channel for Calibration tutorial)

Calibra.: Span calibration is undertaken to ensure accurate gas concentration reading (i.e. ensure that the display reading is accurate and true). We recommend calibration to be undertaken every 6 months. For analytical and highly specific applications, calibration can be undertaken more often to ensure the highest accuracy. If left beyond 6 months, the accuracy of the analyzer will be compromised.

To undertake span calibration from the MENU SCREEN select Calibra. Expose the analyzer to the calibration gas for 1 min. When using calibration gas bottles, maintain a flow of at least 0.5L/min. Edit the gas concentration using left and right buttons so the detector knows the concentration of the calibration gas. After exposure, press EXIT. When complete, a blue floppy disk icon will be displayed.

Calibration
MENU SCREEN

Check: Performs a self-check of the analyzer.
Info: Provides the software version information.
TimeSet: Allows to set the date and time.
Restore: Restores to factory default setting. Email Forensics Detectors to obtain this password.
Exit: Switches back to the main screen.

BATTERY CHARGING

The ANALYZER has a built-in lithium battery and can be charged via mini-USB port. USB Charger must be rated >1.0A for fast charging. Before charging, TURN OFF the analyzer to avoid any potential damage. Charging takes about 4 hours. Do not charge the device in a combustible area. The analyzer has the battery level icon to provide you with an indication of how much battery is left.

OPERATIONAL TIPS

Before turning the detector off don’t forget to flush/purge out the detector by allowing the pump to run for 60 secs to allow clean air to purge.
Ensure tubing and items are clean before storing as to avoid any contamination, residual odors or toxic gases that may poison the sensor.
Ensure periodic calibration every 6 months so that the performance of the detector remains within specification. If the calibration period is >6 months, the detector still operates but accuracy will be compromised

WARNING

KEEP DETECTOR AWAY FROM ELECTROMAGNETC & MAGNETIC INTERFERENCES (i.e. PHONES & MAGNETS)
STORE DETECTOR WITHIN SPECIFICATIONS
IF UNWELL, SEEK CLEAN AIR & MEDICAL ATTENTION.
FOLLOW INSTRUCTIONS AS THE DETECTOR IS VERY SENSITIVE
TO ENSURE ACCURACY, CALIBRATE DEVICE AT LEAST EVERY 6 MONTHS
THE DETECTOR IS NOT RECOMMENDED FOR USE IN FLUE GAS AS THE UNIT DOES NOT HAVE A WATER TRAP NOR A NOX FILTER and PROBE WILL NOT WITHSTAND TYPICAL FLUE GAS TEMPERATURES.
CHECK AND SET ALARM LEVELS APPROPRIATELY TO AVOID HARMFUL EXPOSURE – CONSULT WITH YOUR SAFETY OFFICER OR WITH STATE/FEDERAL AGENCIES.
