9.1.4 M200AU Internal Variables

The M200AU software contains many adjustable parameters. Most of the parameters are set at

time of manufacture and do not need to be adjusted for the lifetime of the instrument. Some of

the variables are user adjustable, they are listed in Table 9-5.

To access the VARS menu press SETUP-MORE-VARS-ENTR. Use the PREV-NEXT buttons

to select the variable of interest, then press EDIT to examine/change the value, then press ENTR

to save the new value and return to the next higher menu. If no change is required, press EXIT.

TPC_ENABLE

The M200AU has temperature and pressure compensation. T/P comp adjusts the output of the

instrument for changes in sample temperature, reaction cell pressure, and atmospheric pressure.

The temperature of the reaction cell controls the sample temperature. The setpoint is 40° C, and

the value of the adjustment parameter is equal to 1.0000 when the reaction cell temperature is

40° C. The temperature compensation increases sample concentration with increasing

temperature to compensate for the drop in density of gas in the reaction cell.

The reaction cell pressure compensation factor is equal to 1.0000 when the cell pressure is about

3.5"-Hg-A. The compensation factor increases sample concentration with increasing cell

pressure to compensate for increased quenching of the chemilumenscent reaction at higher

pressures.

The sample pressure compensation factor is equal to 1.0 at 29.92"-Hg-A. This factor increases

sample concentration with decreasing sample pressure to compensate for a lower head pressure

on the sample flow orifice.

Taken together, the three factors change the output of the instrument very little. The sample

temperature is essentially invariant, and the cell pressure and sample pressure factors tend to

cancel each other. The resultant coefficient has no practical variation with pressure changes due

to weather fronts. Changes in altitude of 1000 feet usually change the output of the instrument by

about .5% if compensation is turned off, much less if it is operating.
