Diagnostics
Thermo Electron Corporation Model 48i Instruction Manual B-15
These commands set the CO concentration alarm minimum value, where
value is set to either floor or ceiling, according to Table B-3. The example
below sets the CO concentration minimum alarm trigger to ceiling.
Send: set alarm trig conc 1
Receive: set alarm trig conc 1 ok
Diagnostics agc int
This command reports the current intensity of the reference channel AGC
circuit. The example below reports that the current AGC intensity is
200,000 Hz.
Send: agc int
Receive: agc int 250000 Hz
bias voltage
This command reports the current IR bias supply voltage. The example
below reports that the bias voltage is -102.3 volts
Send: bias voltage
Receive: bias voltage -102.3 V
diag volt mb
This command reports the diagnostic voltage measurements on the
motherboard. The sequence of voltages is: Positive 24, positive 15, positive
5, positive 3.3, and negative 3.3. Each voltage value is separated by a space.
Send: diag volt mb
Receive: diag volt mb 24.1 14.9 4.9 3.2 -3.2
diag volt mib
This command reports the diagnostic voltage measurements on the
measurement interface board. The sequence of voltages is: Positive 24,
positive 15, negative 15, positive 5, positive 3.3, positive 18 IR, positive 18
MOT, and VBIAS. Each voltage value is separated by a space.
Send: diag volt mib
Receive: diag volt mib 24.1 14.9 -14.9 4.9 3.2 17.9 17.9
