Calibrate IR gas

Electrocution hazard. If relay contacts are connected to AC line voltage, remotely disconnect the power
before opening the upper enclosure door of the analyzer.
Potential Instrument Damage. Delicate internal electronic components can be damaged by static
electricity, resulting in degraded performance or eventual failure.
CO span gas at 1000 ppm or 10000 ppm is necessary to do this procedure.
2
Zero gas can be the carrier gas. Connect the zero and span gases directly to the IR manifold.
Calibrate the IR gas when the IR is out of calibration. Make sure that the feed pressure at the carrier
gas inlet is 40-90 psig.
