Table 6-2: Test Functions Defined
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. See
Section 6.5 for more information.
If DUAL or AUTO Range modes have been selected, two
RANGE functions will appear, one for each range.
STABIL STABILITY mV Standard deviation of O
3
Concentration readings. Data points
are recorded every ten seconds. The calculation uses the last
25 data points.
PRES
SAMPLE
PRESSURE
in-Hg-A
The current pressure of the sample gas as it enters the sample
chamber, measured between the SO
2
and Auto-Zero valves.
SAMP FL
SAMPLE FLOW
cm³/min
(cc/m)
The flow rate of the sample gas through the sample chamber.
This value is not measured but calculated from the sample
pressure.
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 auto-zero
offset and 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 detectort output reading recorded the last
time the UV source lamp shutter was closed.
SLOPE SO
2
measurement
Slope
-
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 SO
2
measurement
Offset
-
The overall offset of the instrument as calculated during the last
calibration activity. The fffset parameter is used to set the zero
point of the analyzer response.
HVPS HVPS V The PMT high voltage power supply.
RCELL
TEMP
SAMPLE
CHAMBER
TEMP
°C The current temperature of the sample chamber.
BOX TEMP
BOX
TEMPERATURE
°C The ambient temperature of the inside of the analyzer case.
PMT TEMP
PMT
TEMPERATURE
°C The current temperature of the PMT.
IZS TEMP
1
IZS
TEMPERATURE
1
°C
The current temperature of the internal zero/span option. Only
appears when IZS option is enabled
TEST
2
TEST SIGNAL
2
mV Signal of a user-defined test function on output channel A4.
TIME CLOCK TIME hh:mm:ss The current day time for iDAS records and calibration events.
