DISPLAY PARAMETER UNITS DESCRIPTION
RANGE Range
- -
Range1
Range2
PPB, PPM,
UGM &
MGM
The full scale limit at which the reporting range of the analyzer’s
ANALOG OUTPUTS are currently set. THIS IS NOT the physical range
of the instrument.
If IND or AUTO Range modes have been selected, two RANGE
functions will appear, one for each range.
H2S STB
1
Stability PPB
Standard deviation of H
2
S Concentration readings. Data points are
recorded every ten seconds. The calculation uses the last 25 data
points.
SAMP FL Sample Flow
cm³/min
(cc/m)
The flow rate of the sample gas through the sample chamber.
PRES
Sample
Pressure
in-Hg-A
The current pressure of the sample gas as it exits the sample
chamber, measured after the sample chamber.
PMT PMT Signal mV
The raw output voltage of the PMT.
NORM
PMT
NORMALIZED
PMT Signal
mV
The output voltage of the PMT after normalization for
temperature/pressure compensation (if activated).
UV LAMP
Source UV
Lamp Intensity
mV
The output voltage of the UV reference detector.
LAMP
RATIO
UV Source
lamp ratio
%
The current output of the UV reference detector divided by the
reading stored in the CPU’s memory from the last time a UV Lamp
calibration was performed.
STR. LGT Stray Light ppb
The offset due to stray light recorded by the CPU during the last zero-
point calibration performed.
DRK PMT Dark PMT mV
The PMT output reading recorded the last time the UV source lamp
shutter was closed.
DRK LMP
Dark UV
Source Lamp
mV
The UV reference detector output reading recorded the last time the
UV source lamp shutter was closed.

The sensitivity of the instrument as calculated during the last
calibration activity. The slope parameter is used to set the span
calibration point of the analyzer.

Offset
mV
The overall offset of the instrument as calculated during the last
calibration activity. The offset parameter is used to set the zero point
of the analyzer response.
