Caution…
Do not use the instrument if the internal fan is out of
order.
The well must be clean before use.
Ensure a free supply of air to the internal fan located at the
bottom of the instrument.
The area around the calibrator should be free of draught, dirt,
flammable substances, etc.
Check the voltage of the power control switch (on/off switch
(230V/115V)). If the voltage of the power control switch
differs from the line voltage, you must adjust the setting of
the power control switch as follows (see fig. 1b):
A. Open the fuse box lid using a screwdriver.
B. Take out the fuse box.
C. Remove both fuses and insert two new fuses.
These must be identical and should correspond to the
line voltage. See chapter 9.0.
B. Turn the fuse box 180° and slide it into place.
Check that the earth connection for the instrument is present
and attach the cable.
Place the parts from the liquid bath kit in the well in the
following order:
Stirring magnet – It is very important that the stirring
magnet is in place and spinning before any calibration is
attempted. The stirring magnet ensures minimum
temperature gradient in the fluid. The magnets teflon
cover will over time be worn down, leaving the magnet
flat on one side. This will reduce the spinning ability. A
magnet with a flat side must therefore be replaced.
Sensor basket – It is very important to place the sensor
basket in the well, as it ensures that the sensors
encounter maximum temperature stability and ensures
that the stirring magnet is not blocked.
