operating in dual or auto range mode. The example below shows that the
NO concentration is 67.2 ppb.
Send: no
Receive: no 6.720E+01 ppb
conv temp
This command reports the current NO
example below reports that the current converter temperature is 320.7 °C.
Send: conv temp
Receive: conv temp 320.7 deg C
cooler temp
This command reports the current PMT cooler temperature. The example
below reports that the current PMT cooler temperature is -2.8 °C.
Send: pmt temp
Receive: pmt temp -2.8 deg C
flow
sample flow
These commands report the current measured flow. The example below
reports that the flow measurement is 0.700 liters/minute.
Send: flow
Receive: flow 0.7 1/m
internal temp
This command reports the current internal instrument temperature. The
first reading is the temperature being used in instrument calculations. The
second temperature is the actual temperature being measured. If
temperature compensation is on, then both temperature readings are the
same. If temperature compensation is off, a temperature of 30 °C is used as
the default temperature even though the actual internal temperature is 27.2
°C. The example below shows that temperature compensation is on and
that the internal temperature is 27.2 °C.
Send: internal temp
Receive: internal temp 027.2 deg C, actual 027.2
perm gas temp
This command reports the current permeation gas temperature. The
example below reports that the permeation gas temperature is 45 °C.
Send: perm gas temp
Receive: perm gas temp 45 deg C
