IMPORTANT To maintain the correct alignment, screws must be tightened in turn.
Tighten each screw a small amount before moving to the next screw. Repeat this process
until all screws are secure.
d. Close the module flap cover.
9. Remove the plug, and reconnect the column end to the detector.
10. Open the gas supplies.
11. Check the gas supply for leaks.
a. Use a handheld electronic leak detector (Thermo Scientific GLD Pro leak detector or
equivalent) to check each fitting for leaks.
b. If you detect a leak, tighten the connection and retest it.
c. Repeat this process until all connections are leak free.
12. If external modules are present, plug the power cable to the AC Input connector of each
external module, and to the wall outlet.
13. Power on the GC.
a. Plug the power cable to the AC Input connector into the back of the GC and to the
wall outlet.
b. Flip up the power switch (breaker) to the position I.
14. Check the module gas connections for leaks.
15. Close the front door of the GC.
Use this procedure for manually measuring the FID fuel and make-up gases.
 To manually measure the FID flow rates
Materials needed
Forceps or tweezers
T10 Torxhead screwdriver
Measuring Tool - Flowmeter Adapter
Electronic flowmeter (Thermo Scientific GFM Pro Flowmeter, or equivalent)
1. Put the GC in standby condition.
2. Turn the flame off. The fuel gases, hydrogen, and air, are automatically closed.
3. Cool the detector to room temperature.
