5.2 Switching on the calibrator / micro calibration bath
Connect the supplied mains plug to a mains outlet.
Actuate the mains switch.
The controller is initialized.
tESt appears on the upper display.
The version number, e.g. rL 2.2, appears on the lower display.
Initialization is completed after approx. 5 sec., the
calibration mode
is then automatically
displayed.
The installed heating and cooling elements automatically adjust the metal block from the
room temperature to the set temperature set at the controller.
5.3 Reference and set temperature display
Upper display (red):
The red, 4-digit, 7-segment display shows the current
temperature of the metal block / liquid bath. When us-
ing the calibrator / micro-calibration bath with more
than one function then the chosen function will be dis-
played in alternation.
Lower display (green):
The green, 4-digit, 7-segment display shows the cur-
rent set temperature of the metal block / liquid bath.
Once the set temperature has been achieved, the radiated heat energy from the metal block /
liquid bath is supplied by short firing pulses, thus ensuring that the temperature inside is kept
constant.
5.4 Stabilizing the reference temperature
The switch on time of the heater is displayed by the red LED OUT 1 an.
During the heating up phase a constantly lit LED dis-
plays the supply of heat energy, a flashing LED indi-
cates that the reference temperature has almost
reached the set temperature and the heat energy is
now being supplied at short intervals.
