11.1 Calibration interval (C.Int)
You can input the interval after which the device reminds you to recalibrate.
The interval times should be chosen according to the application and the stability of the electrode. “CAL”
flashes on the display as soon as the interval has expired.
11.2 Calibration memory (rEAd CAL)
The last calibration is stored with results and date and can be read out.
Display calibration data:
Historical calibration data can be comfortably read out via PC software GMHKonfig or displayed directly at
the device:
Press for 2 seconds:
The display will show:
(configuration level)
Press several times until this is
displayed:
read cal. = “read calibration data”
Press shortly:
switch between:
-
CELL = cell constant
-
C.rEF = reference value, at which cell constant has been adjusted
-
Display of date + time of data set
Quit calibration data set display
12 Accuracy Check / Adjustment Service
You can send the device to the manufacturer for adjustment and inspection.
Calibration certificate - DKD certificate - official certifications:
If the measuring instrument is supposed to receive a calibration certificate, it has to be sent to the
manufacturer (declare test points).
If the device is certificated together with a suitable sensor very high overall accuracies are possible.
Basic settings can only be checked and
– if necessary – corrected by the manufacturer.
A calibration protocol is enclosed to the device ex works. This documents the precision reached by the
production process.
