Model 42i Instruction Manual
Send:
set cal perm gas offset temp 34.5
Receive:
set cal perm gas offset temp 34.5 ok
set cal perm oven offset res res
This command calibrates the permeation oven temperature sensor offset
using a calibrating resistor of value res in ohms.
Send:
set cal perm oven offset res 5000
Receive:
set cal perm oven offset res 5000 ok
span dev
This command reports the span deviation (span check offset). The
following example reports that the span deviation is 1 ppb.
Send:
span dev
Receive:
span dev 1.000 E+00
set span dev value
This command sets the span deviation (span check offset) to value, where
value is a floating-point representation of the gas concentration in current
selected units. The following example sets the span deviation to 345 ppb.
Send:
set span dev 345
Receive:
set span dev 345 ok
zero dev
This command reports the zero deviation (maximum zero check offset).
The following example reports that the zero deviation is 10 ppb.
Send:
zero dev
Receive:
zero dev 1.000 E+01
set zero dev value
This command sets the zero deviation (maximum zero check offset) to
value, where value is a floating-point representation of the gas
concentration in current selected units. The following example sets the zero
deviation to 10 ppb.
Send:
set zero dev 1.000 E+01
Receive:
set zero dev 1.000 E+01 ok
span cal reset
This command reports that the span cal reset is on or off. The following
example reports that the span cal reset it on.
Send:
span cal reset
Receive:
span cal reset on
