set avg time selection
set high avg time selection
set low avg time selection
These commands set the averaging time, high and low averaging times,
according to
Table B-2 . The example that follows sets the low range
averaging time to 120 seconds.
Send: set low avg time 5
Receive: set low avg time 5 ok
bench temp
This reports the current bench temperature. The first temperature 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 0
°
C is used as the
default temperature even though the actual bench temperature is 32.3
°
C.
The example that follows shows that temperature compensation is on and
that the bench temperature is 32.3
°
C.
Send: bench temp
Receive: bench temp 032.3 deg C, actual 032.3
o3
high o3
low o3
These commands report the measured O
3
concentrations when operating
in single range, or high and low O
3
when operating in dual or auto range
mode. The example that follows shows that the O
3
concentration is 67.2
ppb.
