Switching on, cool down and switching off
IMPORTANT!
Follow the instructions and notes of the section (
§ 4.1).
For reasons of safety, upon switching on the calibrator, the fan runs at the fastest speed. As
soon as the internal reference has measured a safe block temperature, the fan speed is
adjusted.
Switching on:
Turn on the main switch.
The controller is initialised.
tESt appears in the upper display.
The version number e.g. rL 2.2 appears on the lower display.
Initialization is completed after approx. 5 seconds and the
calibration mode
(
§ 5.2) is
automatically displayed.
The installed heating elements automatically adjust the metal block from the room
temperature to the set temperature set at the controller.
IMPORTANT! Keep in mind after transport or storage!
After transport, storage or long periods of non-use, moisture can seep into the heating
elements (magnesium oxide).
For drying, the calibrator must be slowly heated up. During this process, the calibrator
has not yet reached the required insulation voltage for protection class I.
For drying the heating elements, heat the calibrator for at least 15 min to 120 °C.
Cool down the calibrator:
CAUTION! Risk of burns!
The calibrator can become very hot when in operation. Touching hot parts can result in
serious injuries.
Never touch the metal block, the tank, the adapter sleeve or the test specimen at
temperatures above 35 °C or below 10 °C.
In order to cool down the metal block / calibration liquid quickly, set the set
temperature to a low temperature, e.g. room temperature.
The installed fan gently and automatically switches to a higher speed for heating
instruments, thus providing more cooling air. The LED OUT 2 indicates the status of the
output for the fan control. If the LED OUT 2 lights up, the fan is running at high speed. If the
LED OUT 2 does not light up, the fan is running at low speed.
The controller switches the active cooling on for heating / cooling instruments. The LED OUT
2 indicates the status of the output for the active cooling. If the LED OUT 2 lights up, the
active cooling is running. If the LED OUT 2 does not light up, the cooling is not active.
