The numerical values behind σ and σ
can be set as conductivity values of the high-value calibration
H L
block and of the low-value calibration block at a temperature of 20 °C and are used for calibration.
To select a unit, read chapter 5.4.7.
The values of a and a can be set as temperature coefficients of the respective block. These
H L
positions are factory-set.
When you see the screen shown in image 9, you can move the cursor up and down by means of
the arrow keys to select the value you would like to adjust. After confirming your selection with "OK",
you can change a value by using the arrow keys again. When you have entered the desired value,

back to the settings screen, press "OK". To change the values more quickly, press and hold the
arrow keys.
The possible values for σ and σ
range from 4.50 to 64.0 MS/m and 7.70 to 111.0 %IACS.
H H
The value σ must be higher than the value σ
. For a and a values from 0.0000 to 0.0300 can be
H T H L,
selected.
Note:
To open this setting, press the "SAVE" key four times. When you confirm with the "OK" key, the
