2- or 3-wire connection
It is also possible to connect a 2- or 3-wire probe to the CTH6200. However, it should be
noted that measured errors occur due to cable and contact resistances, but these can be
compensated for by the zero point correction.
4-pin mini DIN connector
It is also possible to fit a 4-pin mini-DIN connector with interlocking for self-assembly.
4.6.1 Available temperature probes
The hand-held has been designed so that all sensors of the CTH series can be
connected without the need for any readjustment, see chapter 10 “Specifications”.
4.6.2 Connecting/replacing the temperature probe
WARNING!
Risk of burns!
The temperature probes can be extremely hot or cold.

Let the temperature probe cool down sufficiently before replacing it!
Before switching the instrument on, connect the temperature probe,
otherwise it may not be correctly identified by the instrument.

2. Connect the hand-held thermometer and the temperature probe. To do this, connect
the 4-pin mini-DIN connector on the hand-held to CH1 in accordance with the
