Gas Analyzer Operation - EMS 5003 Operator's Manual

Shortly after applying power, the analyzer will display the EMS logo & world start up screen.
It will disappear once and reappear (Figure 8) for approx.15 sec. then switch to the Home sampling
screen (Figure 9). This starts the analyzer warm-up mode and will continue for approximately 5 to
10 minutes, depending on ambient temperature. Once the warm-up is complete, the analyzer will
go into the "ZEROING" mode to set all the gases to zero. Then the gas sample mode will display all
the gas values (Figure 10). 4 Gas units will show CO2, CO, HC, O2 (figure 11) Note: Below the
