Control Description
NO PMT cold block temperature. Typically 4300 mV for 7
C.
NO DC power supply composite voltage output. Typically
2500 mV
NO Reaction Cell Pressure in mV. Typically 1270 mV for
5" Hg-A at sea level. Is an absolute pressure so higher
values means higher absolute pressures.
NO Ozone flowmeter voltage. Typically 3200 mV at
250 cc/min.
NO Converter temp. Typically XXXX mV at 700 C
NO HVPS programming voltage. Output of HVPS is
1000x value present. 700 mV = 700 VDC output.
NO Output of NO
NO Output of NO channel in mV.
NO Output of NO
NO Test Channel output. Also second NO
YES NO DAC programming voltage. The following 3
x
signals can be set to output specific voltages to each
DAC. Use in conjunction to ANALOG OUTPUT test
to check each DAC output channel. The value keyed in
should appear on the appropriate analog output
channel. This value overrides data being written from
the analyzer. Value reverts to instrument output when
function is exited.
YES NO DAC programming voltage. See above for
description.
YES NO DAC programming voltage. See above for
