To calibrate an mA output, proceed as follows:
1. Enter the PIN (see chapter "12.2 PIN Entry").
2. Tap and hold the
3. The display shows the code entry.
The cooler should then be in a steady state at 5 °C [41 °F] (absolute value control) and provide one of
the following values:
• 8 mA (in case of 4 - 20 mA)
• 5 mA (in case of 0 - 20 mA)
The cable length is not limited and the cable does not need to be shielded.

If a calibration error occurs and the mA output has been calibrated, the
limiting values also change!
-key for a short moment.
Enter the code "310" for the calibration of the lower value of the mA
output.
Now connect a current meter to the connector of the mA output. This
current meter should measure a value close to 1 mA. You can now
adjust this value in 0.0054 mA steps with the up and down arrow keys.
After the adjustment, the current meter should display 1 mA as
accurately as possible. Accept the value with the
Enter the code "C311" for the calibration of the upper value of the mA
output.
Now connect a current meter to the connector of the mA output. This
current meter should be used to measure a value close to 20 mA. You
can now adjust this value in 0.0054 mA steps with the up and down
arrow keys until the current meter displays 20 mA as accurately as
possible. Accept the value with the
