UNITS – selection of units for path length (in, ft, cm, m),
pressure (psiA, barA, kPa, torr, atm) and temperature (ºF,
ºC, ºK).
SYSTEM I/O – allows set up and assigning of analyzer
Analog and Digital I/O.
SYSTEM – displays analyzer information (serial number,
Fat date, password, software version, launch/detect unit
temperatures), allows setting of date/time, gas type.
VALVE CONTROL ¬– allows for manual and/or automatic
control of the valve driver output signals.
SIGNAL PROCESSING – Factory set parameters only
LASER SPECTRA & CONTROL – displays spectra and
allows manual control of laser.
SYSTEM I/O - ANALOG OUTPUT
CHANNEL 1 to 3 – configuring each 4 to 20mA channel
to output Concentration, Transmission, Gas Temperature,
Gas Pressure or None.
WARNING MODE – setting of mA output response during
analyzer warnings (Block, Track, Hold).
FAULT MODE – setting of mA output response during
analyzer warnings (Block, Track, Hold).
BLOCk MODE LEVEL – specifies the analog output level
in block mode (high 20mA or low 3.3mA).
FIELD LOOP CHECk – allows specified 4-20mA output
levels to check and distinguish between the three analog
output connections; select analog output channel 1, 2, or
3 to check and input new value to output and press enter
to activate.
AO CH CALIBRATION – Pre-Calibrated at factory and not
normally required. Allows calibration of 4 to 20mA output
channels; follow onscreen instructions.
