4. Operating the Calibrator
4.7 Recalibration and Adjustment
The temperature calibrators of the CTD 9300 series have been
calibrated and tested ex works according to accepted standards.
Recalibration and adjustment of the device, however, is recommend
if used periodically.
There are no compulsory regulations for recalibration intervals of
temperature calibrators since these depend on the conditions of
application and are thus in the responsibility of the user.
Independent of this fact, we recommend annual recalibration at our
DKD calibration laboratory. Any recalibration performed by WIKA
additionally includes free checking of the functions and internal
system parameters. During this process, any errors of measurement
are reduced to a minimum within the scope of measurement
uncertainty by proper adjustment. Firmware updates can also be
performed.
The DKD calibration certificate also gives you the certainty that
your calibration results are based on national standards and the
errors of measurement do not exceed the error limits specified.
Calibration is a matter of trust. For this reason, entrust only
competent DKD calibration laboratories that has been certified in
compliance with the standard DIN EN ISO/IEC 17025 with the
calibration of your valuable devices.
Package the devices you are shipping for recalibration with great
care and use the original packaging, if possible.
To guarantee that the calibration process is performed as fast as
possible, we recommend contacting our calibration workshop by
phone in advance to make an appointment.
