Example a) Insert a suitable thermometer into the bath (long enough and far enough).
b) Remove the external consumers and turn the setting knob of the pump outflows to the
right side.
c) Set the setpoint to a temperature where you use to work (e.g. set the setpoint to 45°C
(
➾
Section 6.3.)
d) Wait until the actual bath temperature has reached the setpoint temperature of 45°C
and until the indication on the reference thermometer does not change any more.
e) Remove the reference thermometer, which shows e.g. 44,8 °C.
f) Select CAL on the display and go forward as mentioned under point 1-7 (see
above).The actual bath temperature switches from 45°C to 44,8°C and the unit starts to
heat up until the actual bath temperature has reached 45°C. (
!
the reference
thermometer should also indicate 45°C).
