MOLY TEMP

315 ± 5° C

°

 

Moly temp is controlled by the CPU to 315 C. After cold start it

 

 

requires about 30 min to come to temperature. After temperature is

 

 

reached temperature should not vary more than ± 5° C. See

 

 

Section 9.3.4 for troubleshooting. Warning limits are < 290° C and

 

 

> 320° C.

 

 

 

RCEL PRESS

3.5 ± 1 in-Hg-A

RCEL is the pressure in the Reaction Cell. The instrument is very

 

 

sensitive to variations in reaction cell pressure. A 10% change in

 

 

output per 1"Hg pressure is typical. The pressure reading will

 

 

change when the NO/NOx and Pre-reactor valves switch,

 

 

otherwise it should remain constant. The reaction cell pressure

 

 

will be lower at higher altitude due to lower pump back-pressure.

 

 

Pressures higher than the acceptable range will decrease

 

 

instrument noise performance and sensitivity.

 

 

 

SAMP PRESS

29.5"Hg at sea

The sample pressure is taken upstream of the reaction cell. It

 

level

usually runs about 0.5" less than ambient pressure due to the

 

 

restrictions in the sample intake tubing. Sample pressure should be

 

 

within ± 1"Hg of atmospheric pressure. The pressure sensor used

 

 

reports absolute pressure and therefore is sensitive to altitude,

 

 

weather fronts, and room air conditioning. Changes due to altitude

 

 

is about 1" per 1000 ft., other changes are ± 0.4" maximum.

 

 

Pressurizing the sample inlet will cause the M200AU to be noisy

 

 

and to shift its reading.

 

 

 

SLOPE

1.0 ± 0.3

This is the software slope value. It operates like a software gain

 

 

pot. Refer to Table 7-18 on Calibration Quality for additional

 

 

information.

 

 

 

OFFSET

0 – 10, +150

This is the software offset value. It operates like a software DC

 

 

offset pot. Refer to Table 7-18 on Calibration quality for

 

 

additional information.

 

 

 

TIME

HH:MM:SS

This is the time of day clock readout. It is used to time the

 

 

AutoCal cycles. The speed of the clock can be adjusted by the

 

 

CLOCK_ADJ variable in the VARS menu. The clock can be set

 

 

via SETUP-CLOCK-TIME from the front panel.
