For device with external temperature probes, it is advisable to place only an
external probe into the calibration chamber generating the relevant quantity.
If the calibration is carried out at different temperature than ambient
temperature, a sufficient part of the cable with the probe must be inserted
into calibration chamber. This can prevent heat transfer between the
chamber and the environment through the cable.
The measurement standard (temperature, relative humidity, pressure, and
CO
2
) is also placed in the calibration chamber.
During adjustment proceed
in the same way as described above for calibration
.
Close and run the calibration chamber. Set to calibration chamber to a
first
adjustment point
value.
Wait for the device to stabilisation.
The device stabilization time can be
counted from the moment when the controlled quantity has stabilized in the
calibration chamber. When device is stabilised note value of the standard
and value of device.
Repeat this procedure for the
second adjustment point
(if necessary).
Save new adjustment constants
).
After the adjustment procedure it is necessary to make device calibration
procedure.
