Gas Analyzer Operation - EMS 5001 Operator's Manual

Immediately after applying power, the analyzer will display 8's (Figure 9) for a few
seconds and then flash dashes (Figure 10). This starts the analyzer warm-up mode and will
continue for approximately 5 to 10 minutes, depending on ambient temperature. Once the
warm-up mode is complete, the analyzer will go into the gas sample mode (Figure 11) and the
Sample LED will turn ON. Note: If the display only shows decimal points (Figure 12),
check the "Display/Computer" switch on the back of the analyzer. The switch should be
in the display position. Disconnect power before changing the switch position.

Once the analyzer has completed the warm-up process the sample hose can now be
connected and the probe placed in the tailpipe.
Caution: Exhaust gases pass through the gas analyzer and vent through its ex-
haust tubing. Use the analyzer in a well vented area.
Note: Gas analyzers are designed for diagnostics and verification of repairs. The
sample probe should be removed from the tailpipe after taking readings to prolong
analyzer life and save on maintenance costs.
The pump will continue to operate as long as the CO2 level is above 3%. The pump will
automatically shut-off after the CO2 level has been below 3% for approximately 15 minutes.
The pump can be turned back on by depressing the "Z" button.
Caution: Monitor the clear hose between the filter assembly and the cabinet. If
moisture appears in the tubing, remove the probe from the tailpipe and disconnect the
sample hose from the analyzer immediately. Use compressed air to remove moisture
from the sample hose. Operate the analzyer without the exhaust hose connected, until
the moisture is removed. It may be necessary to replace the filters. Once the lines are
dry, normal operation can continue.
