4-38 | Model 933S UV Analyzer
Assignment
Defines (Output Signal Assignment, or OSA) code for each of the four
analog outputs. These are typically assigned at the factory, according
to customer specifications.
Species Iout
The gas type of interest for the current output with and without
Track and Hold (T&H), and displayed as ppm or %, that is as-
signed to each channel. 0 - N/A is selected if no output is assigned
to the channel.
Species Vout
The gas type of interest for the voltage output with and without
Track and Hold (T&H) that is assigned to each channel. 0 - N/A is
selected if no output is assigned to the channel.
Current Outputs
Low Scale
The current low scale setpoint corresponding to 4 mA
DC
. Enter ‘0’
if an output is not used.
Full Scale (High Scale)
The current full-scale setpoint corresponding to 20 mA
DC
. For ex-
ample, if Scale 1 = 1000 PPM, Output 1 would read 20 mA at 1000
PPM and 4 mA at 0 PPM. Enter ‘0’ if an output is not used.
Zero (mA)
The measured current (mA) in the current output loop when the
output is set to zero scale during the Zero calibration procedure.
This is factory-calibrated.
Span (mA)
The measured full-scale current (mA) in the current output loop
when the output is set to full-scale during the Span calibration
procedure. This is factory-calibrated.
Result
The real time output value for each output.
Voltage Outputs
Low Scale
The voltage Low Scale setpoint corresponding to 1000 mV
DC
. Enter
‘0’ if an output is not used.
High Scale (Full Scale)
The voltage Full Scale setpoint corresponding to 5000 mV
DC
. Enter
‘0’ if an output is not used.
