Description
Sensor housing CJC voltage
(valid only with Type 3 sen-
sor).
The highest sensor housing
temperature read since
power on.
This is the sensor housing
type setting through the
DIP switch. (0 = Type 1, 1 =
Type 2, 2 = Type 3, 3 = Invalid)
This determines whether a
calibration cycle will auto-
matically step through,
turning solenoids on and
off to switch test gas, or
wait for an operator to
manually switch gases and
acknowledge.
See FF-891, Section 5.3.
Total number of messages
sent to the transducer a/d
board.
Total number of failed a/d
board message attempts.
Total number of timed out
a/d board message at-
tempts.
