10.1.3 Calibration interval

The calibration evaluation is displayed as a sensor symbol.

The sensor symbol flashes after the adjusted calibration interval has expired. It 
is still possible to measure.

Setting the calibra-

tion interval

The calibration interval is set to 7 days in the factory. 
You can change the interval (1 ... 999 days):

10.1.4 Settings for ORP measurements

The settings for ORP measurements are made in the menu for calibration and 
measurement settings of the pH/ORP measurement. To open the settings, dis-
play the required measured parameter in the measured value display and 
press the 

<ENTER>

key. After completing the settings, switch to the measured 

value display with 

<M>

.

In the following table, only those settings are listed that influence the ORP mea-
surement. 

Default settings are printed in 

bold

.

To ensure the high measuring accuracy of the measuring system, 
calibrate after the calibration interval has expired.
