Control Description
YES Status Bit - In Diagnostic mode
Logic High = 6400A in Diagnostic mode
Logic Low = Not in Diagnostic mode
YES Status Bit - Power OK
Logic High = Instrument power is on
Logic Low = Instrument power is off
YES Status Bit - System OK
Logic High = No instrument warning present
Logic Low = 1 or more alarm present
YES Status Bit - HVPS alarm
Logic High = HVPS out of spec
Logic Low = HVPS within spec
NO Current PMT voltage. Same as PMT voltage in TEST
menu. Bi-polar, typically in 0-5000mV range. A
constant value of 5000mV indicates offscale.
NO Reaction Cell temperature. 3500 mV for 50
NO Box Temperature. Typically 1800 mV for 25
NO IZS permeation tube oven temp. Typically 3500 mV
o
for 50 C.
NO PMT cold block temperature. Typically 4300 mV for
o
7 C.
NO DC power supply composite voltage output.
Typically 2500 mV.
NO Sample pressure in mV. Typical sea level value =
4300mV for 29.9" HG-A.
NO Sample flow in mV. Typical value is about 3200 mV
for 650cc/min.
NO HVPS programming voltage. Output of HVPS is
1000x value present.
NO Output of SO
