Switching On
Before switching on the instrument for the first time, ensure that the power requirements
indicated on the rating label correspond to the power supply voltage being used.
Note
No other instruments should be connected to the circuit used for the cryostat, as the compressor needs high
surge currents when started.
Do not use multi-socket power outlets with small wire sizes for the supply of the instrument.
•
Insert the supplied power cord into the power socket and then connect the power cord to the
mains supply.
•
Install the blade holder if necessary.
•
Close the heated window.
•
Turn on the power switch.
Note
The default setting of the blade holder and specimen head temperature are -15°C.
The cooling phase will take approximately 2 to 3.5 hours depending on the set chamber temperature.
