Chapter 4. Calibration

XMTC User’s Manual

4.3 Required Equipment and Materials

To calibrate the XMTC, you will need the following equipment and materials:

•

XMTC Calibration Sheet

•

+24 VDC, 1.2 A power supply (system power, if unit is installed in a system)

•

Zero gas

•

Span gas

•

Reference gas (for the 4-Port version - the reference gas is usually the same as the span gas.)

•

Sample system or individual components (e.g. flow meter, needle valve, pressure regulator) for connecting
zero and span gases and controlling pressure and flow rates

Note:

The accuracy of the calibration will only be as accurate as the composition accuracy of the zero and span
gases.

WARNING!

The calibration procedure described in this section requires the use of specialized

apparatus and should be performed only by properly trained personnel.

WARNING!

Do not use explosive gas mixtures to calibrate the XMTC.
