» How to calibrate the total gas with 100% methane

Instructions for calibration. You buy the tank, and MSI will provide free refills of the test gas! We carry 1% Methane, 99% Methane, and a 1% blend for the chromatograph

Video Coming Soon.... but until then, here's how:

Zero the TCD detector, and attach the 100% methane (green label) to the Sample In port at the back of the MLogger. 

1. Open the valve on the bottle, and verify that the ball valve is turned to Rig.
2. Then check the MAIN FLOW meter to verify that gas is flowing from the bottle. The TG FLOW should be set at .5 SCFH air.
3. Observe the Total Gas climb until it reaches a maximum and begins to settle. 
4. Left click on Setup in the MControl tool bar and then left click on the Gas Detector tab. 
5. Look at the signal voltage for the TCD filament from the Status bar in MControl.  Enter that number in the field labeled TCD Voltage at 100% Gas. 
6. Left click Apply and left click OK.

Calibration Values Will Remain In the MLogger Until Nuked
