332 GAS ANALYZER

Gas Analyzer Warm-Up

If the Gas Analyzer has not completed its warm-up cycle, this screen is displayed when

accessing any of the Gas Analyzer functions (Data List, Manual Snapshot, and Zero

Bench). The warm-up cycle requires from 5 to 15 minutes. The timer shows the time taken

by the warm-up cycle.

A ***CHECK FILTERS*** reminder is displayed during warm-up; this is an ideal time

to perform the recommended daily filter inspection. Refer to <MAINTENENCE>

( Section 6.0 Gas Analyzer Maintenance on page 343) for filter check procedure.

After the warm-up is complete, the Gas Analyzer enters a purge cycle. During a purge,

ambient air is drawn into the analyzer to flush the unit of any latent sampled gases.

After the purge completes, the gas parameters are zeroed. The Tester emits a beep when

the Gas Analyzer completes its warm-up cycle.

Warm-Up Bypass

Any time power is interrupted to the Gas Analyzer (e.g., during engine crank), the

analyzer needs to recalibrate its internal HC, CO, and CO2 sensors. If power is lost for a

short period of time (such as 30 seconds or less), the sensors are able to stabilize to within

an acceptable accuracy quickly (about 50 seconds). In this case, the full warm-up can be

bypassed, and a warm-up period of only 50 seconds is necessary.

If power is lost to the Gas Analyzer, this screen is displayed.

If communication with the Gas Analyzer is reestablished within 30 seconds of initially

losing power, the <WARMUP BYPASS> screen is displayed instead of the normal

<WARMUP> screen.
