2. Place the magnetic stirrer into the micro bath.
3. Insert the sensor cage.
4. Insert the DUT into the sensor cage, before filling, to account for its volume.
5. Fill the micro bath with calibration liquid.
Note: Observe the maximum fill level and leave sufficient reserve space for an additional
rise in the level.
6. If necessary, remove the DUT.
7. Screw the work cover into place.
8. Insert the DUT through the work cover into the micro bath.
Tub insert filling procedure:
1. Unscrew the transport cover of the tub insert.
2. Insert the tub insert into the micro bath tank using the sleeve exchange tool.
3. Place the magnetic stirrer into the tub insert.
4. Insert the sensor cage.
5. Insert the DUT into the sensor cage, before filling, to account for its volume.

4.3.6 Integrated Measuring Instrument
The following section applies to Liquid PTC 165i and Liquid PTC 255i with the integrated
measuring instrument.
4.3.6.1 Connecting the DUT (Thermocouple)
1. Connect the cable ends to the terminal connectors, or thermocouple adapter, to the
appropriate inputs.
2. Connect the cable screen to the earthing socket if necessary.
4.3.6.2 Connecting the DUT (mA or V)
Connect the temperature sensor to the integrated measuring instrument as follows:
•
Current signal:
1. 3-wire DUT with voltage supply from calibrator:
a. Voltage supply for test specimen: socket “+24 V out”.
b. Signal: “mA in”.
c.
GND: GND
2. 2-wire DUT with voltage supply from calibrator:
a. Voltage supply for test specimen: socket “+24 V out”.
b. Signal: “mA in”.
3. 2-wire DUT with voltage supply from calibrator:
a. Signal: “mA in”.
b. GND: GND
