4.1.2 Gases

Noise Meas activates the noise
measurement.
Sample gain adj adjusts the sampling
pump gain, i.e. for
adjusting the sample flow
measurement.
Pump ctrl A manual control for the
sampling pump.
Zero valve ctrl A manual control for the
zero valve.
Service Data
CO % field shows real-time
2
concentrations.
CO noise-% is standard deviation of
2
concentration.
CO /channels A-E

mV field: signal is scaled
to mV.
Gain: User gain. It is
scaled as (User
gain)/(Factory gain).
O2, N2O, AA Not in use
ID Not in use
ID unrel. Not in use
MAC Not in use
Sample Flow is calculated from differential pressure and adjusted by the module. Zero value as
measured during initialization when the pump is off. Gain: sample flow measurement can
be calibrated by adjusting the gain.
Ambient Ambient pressure is measured continuously. Amb-Work: ambient pressure - sampling
system internal pressure.
Fall time Not in use
CO -O Delay Not in use

Lamp The state, PWM control, and current of the lamp are shown.
Fan Not in use
Zero Valve Can be toggled between the measurement state (MEAS) and the zeroing state (ZERO).
Occl Valve Not in use
Temp Temperatures measured by the module from TPX, CPU, and OM.
