sp conc
high sp conc
low sp conc
These commands report span concentration in single range mode, or the
high and low span concentrations in dual or auto range mode. If the mode
is incorrect, the instrument responds with “can’t, wrong settings”. The
example that follows reports the span gas concentration in single range
mode.

Receive:
sp conc 1000
set sp conc
value
set high sp conc
value
set low sp conc
value
These commands set the span concentrations to user-defined values to
value
, where
value
is a floating-point representation of the span
concentration in current selected units. The example that follows sets the
span concentration to 80 ppm in the single range mode.
Send:
set sp conc 80000
Receive:
set sp conc 80000 ok
pres cal
This command reports the pressure recorded at the time of calibration. The
example that follows shows that the pressure at calibration is 85.5 mmHg.
Send:
pres
cal
Receive:
pres cal 85.5 mmHg
set pres cal
This command automatically sets the current pressure as the calibration
pressure. The example that follows successfully sets the calibration pressure
to 120.5 mmHg.
Send:
