DESCRIPTION

 

 

 

 

MGM

 

If AUTO Range mode has been selected, two RANGE functions will

 

RANGE1

 

 

 

 

appear, one for each range:

 

RANGE2

 

 

 

 

RANGE1: The range setting for all analog outputs.

 

 

 

 

 

 

RANGE2: The HIGH range setting for all analog outputs.

 

 

 

 

 

 

If the IND Range mode has been selected, three RANGE functions will

 

RANGE1

 

 

 

 

appear, one for each range:

 

RANGE2

 

 

 

 

RANGE1: NOx concentration output un A1.

 

RANGE3

 

 

 

 

RANGE2: NO concentration output un A2.

 

 

 

 

 

 

RANGE2: NO2 concentration output un A3.

 

NOX STB

STABILITY

 

PPB

 

The standard deviation of concentration readings of the selected gas.

 

 

 

Data points are recorded every ten seconds. The calculation uses the

 

 

 

 

 

 

last 25 data points.

 

SAMP FLW

SAMPFLOW

 

CC/M

 

Gas flow rate of the sample gas into the reaction cell.

 

OZONE FL

OZONEFLOW

 

CC/M

 

Gas flow rate of O3 gas into the reaction cell.

 

PMT

PMT

 

MV

 

The raw signal output of the PMT.

 

NORM PMT

NORMPMT

 

MV

 

The signal output of the PMT after is has been normalized for temperature,

 

 

 

pressure, auto-zero offset, but not range.

 

 

 

 

 

 

 

AZERO

AUTOZERO

 

MV

 

The PMT signal with zero NOX, which is usually slightly different from 0 V.

 

 

 

This offset is subtracted from the PMT signal and adjusts for variations in

 

 

 

 

 

 

the zero signal.

 

HVPS

HVPS

 

V

 

The output power level of the high voltage power supply.

 

RCELL TEMP

RCELLTEMP

 

C

 

The temperature of the gas inside the reaction cell temperature.

 

BOX TEMP

BOXTEMP

 

C

 

The temperature inside the analyzer chassis.

 

PMT TEMP

PMTTEMP

 

C

 

The temperature of the PMT .

 

IZS TEMP1

IZSTEMP

 

C

 

The temperature of the internal span gas generator's permeation tube.

 

MOLY TEMP

CONVTEMP

 

C

 

The temperature of the analyzer's NO2 NO converter.

 

RCEL

RCELLPRESS

 

IN-HG-A

 

The current pressure of the sample gas in the reaction cell as measured at

 

 

 

the vacuum manifold.

 

 

 

 

 

 

 

SAMP

SAMPPRESS

 

IN-HG-A

 

The current pressure of the sample gas as it enters the reaction cell,

 

 

 

measured between the NO/NOx and Auto-Zero valves.

 

 

 

 

 

 

 

NOX SLOPE

NOXSLOPE

 

 

 

The slope calculated during the most recent NOx zero/span calibration.

 

NOX OFFS

NOXOFFSET

 

MV

 

The offset calculated during the most recent NOx zero/span calibration.

 

NO SLOPE

NOSLOPE

 

 

 

The slope calculated during the most recent NO zero/span calibration.

 

NO OFFS

NOOFFSET

 

MV

 

The offset calculated during the most recent NO zero/span calibration.

 

TEST

TESTCHAN

 

MV

 

Displays the signal level of the Test Function that is currently being

 

 

 

produced by the Analog Output Channel A4.

 

 

 

 

 

 

 

TIME

CLOCKTIME

 

HH:MM:SS

 

The current time. This is used to create a time stamp on DAS readings,

 

 

 

and by the AutoCal feature to trigger calibration events.

 

 

 

 

 

 

 

1Only appears if Internal Span Gas Generator option is installed.
