6.2.4 Measuring resistance and temperature with a resistance thermometer

The model CEP3000 offers three possibilities for measuring the resistance (Ω) and the
temperature with a resistance thermometer: 2-, 3- and 4-wire measurement. The highest
accuracy is obtained with a 4-wire connection.
Figures 4 - 6 show the connection of the model CEP3000 for the three different
measurement types.
1. In order to select the RTD mode, press the RTD key. Then, select the desired resist-
ance thermometer type with the RTD key.
2. The model CEP3000 must be operating in the input mode.
Select the desired connection configuration (2-wire, 3-wire or 4-wire) by using the up
and down arrow key.
