9.7.4. Example: 3-point calibration for internal control
In the temperature range from 80 °C to 160 °C the calibration curve of the
temperature sensor (TT) is to be adjusted to the actual temperatures at
measuring point (CT).

1. Set circulator to internal control:
 The type of control can be set only in the –OFF- mode.
80.00 °C
120.00 °C
160.00 °C
2. Set working temperature setpoint
See standard display line 1
• Example 80.00 °C
Press the keys
and and confirm by pressing .
• The bath is heated up.
Wait for approx. 5 minutes until the temperature is constant.
3. Reading of temperature measuring device
Read the value of measuring point CT on the device and enter under menu
item > CalValue X< by using the keypad.
