All testo Saveris probes are adjusted in the factory, which is
confirmed by the corresponding adjustment report. Calibration
certificates can be ordered separately, see
Accessories and
spare parts
page 173.
For consistently reliable data, we recommend carrying out probe
calibration and any necessary adjustment at regular intervals, e.g.
every year. This can be implemented on or off site.
7.3.1.
On-site calibration and adjustment
The Saveris adjustment software (article no. 0572 0183) is required
for this.
Advantages: calibration while the system is running and simple
documentation by adding an annotation, plus the importing of
adjustment data
Disadvantages: accuracy or comparability of the reference system
measurement data.
After successful adjustment, the current adjustment data is stored
in the probe. At the same time, the adjustment software generates
an adjustment file that can be imported into the Saveris software,
see
Settings for the radio probe
page 123 and
Ethernet probes
page 125.
Ensure that an external humidity probe always remains
attached to the radio or Ethernet probe with which it
was adjusted.
7.3.2.
External calibration and adjustment
Advantages: accuracy, via separate measurement as per a suitable
calibration standard, e.g. in an air-conditioning cabinet.
Disadvantages: probe must be removed from running system.
Two different procedures may be used to carry out external
calibration and adjustment.
Procedure 1
Here the probe removed from the system is not replaced, no
measurement data is recorded during the calibration and
adjustment.
1. Press the connect key on the probe once to enforce one last
data transmission.
2. Send the probe to the calibration laboratory, without removing it
as a component in the startup wizard.
3. When the system alarm “Missing probe connection” appears,
acknowledge this once.
