After transporting, wait at least 4 hours before turning the instrument on. This waiting
period is necessary to allow the compressor oil, which may have been displaced during
transport, to return to its original position. Failure to comply with this may cause dam-
age to the instrument.
• Switch the instrument on at the circuit breaker. The instrument is now initialized.
• The instrument is factory-configured as follows:
Time: 00:00
Defrost time: 23:45
Chamber cooling: On
(Indication of the temperature)
Peltier element: Off
(Display "PE")
• Program the desired values as described under 6.2.1 to 6.2.3.
In normal operation, a pressure compensation shortly before the compressor starts up
might lead to a hissing sound.
The software version "0.40" (shown here only as an example) is displayed
in the 4-digit display for the time. This display disappears after 2 seconds
and switches to the display of the instrument type "1860". The standard
time is then displayed.
