The model CEP3000 oers 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 dierent

measurement types.
