mA Output for the Temperature Measurement inside the Cooling Block

The mA outputs built-in by M&C are factory calibrated and set to the range "4-20 mA". Later purchased
mA outputs must be calibrated.
14.1

mA Output Range Selection

The optional mA output can be changed from 4-20 mA to 0-20 mA. To select the mA range, 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.
14.2 mA Output Calibration for the Temperature Measurement inside the Cooling
Block
The mA output built-in by M&C are factory calibrated. If required, the basic accuracy of the mA output
can be optimized by recalibration.
A later installed mA output must be calibrated. The mA output is suitable for a maximum load of 500 Ω
only.
During calibration, first the lower and then the upper value of the mA output will be calibrated.

Current limitation:
The current output limits in the case of 4 - 20 mA in the lower range to 3.8 mA and in the upper range
to 20.5 mA.
In the case of 0 - 20 mA, it limits the upper range to 20.5 mA.

Enter the code "015". Confirm the code with the
display of the preset range appears.
The default value "4-20", which stands for 4 to 20 mA, appears on the
display. The whole display is blinking here. Use the
to switch between "4-20" and "0-20".
Press to confirm your change or
making any changes. After changing or aborting the display shows the
cooler temperature again.
If the mA output is ordered when ordering the instrument, the mA
output is calibrated at the factory. If a mA output is purchased by the
customer and retrofitted by the customer, the calibration must be
carried out by the customer.
Optionally, the device can be sent to M&C for retrofitting.
The mA output is set to 4 - 20 mA as standard, but can be changed to
0 - 20 mA on the instrument. In both cases the mA range corresponds
to the temperature range -10 °C to +50 °C [14 to 122 °F].
