Control Description
YES Status Bit - Flow alarm
Logic High = Sample/Ozone flow out of spec
Logic Low = Flows within spec
YES Status Bit - Temperature alarm
Logic High = Rxcell, Conv, Box temps out of spec
Logic Low = Temps within spec
YES Status Bit - In Diagnostic mode
Logic High = M9110AH in Diagnostic mode
Logic Low = Not in Diag 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 warnings present
Logic Low = 1 or more alarms present
YES Status Bit - Autorange High Range
Logic High = M9110AH in high range of autorange
mode
Logic Low = M9110AH in low range of autorange
mode
NO Current PMT voltage. Same as PMT voltage in TEST
menu. Bi-polar, typically in 0-5000 mV range. A
constant value of 5000 mV indicates offscale.
NO Sample pressure in mV. Typical sea level value = 4300
mV for 29.9" Hg-A.
NO Reaction Cell temperature. Typically 3500 mV for
50 C.
NO Box Temperature. Typically 1800 mV for 25 C
NO Temperature of the sample flow control orifice.
Typically 3500 mV for 50 C.
