If the selected temperature
corresponds to the actual
temperature
(to within ±2°C),
a small bead of melted silver
will appear at the tip of the
silver wire. In this case, it will
not be necessary to enter a
calibration offset.
If the silver wire has partially or
completely melted to a clump,
this means that the temperature
is
too high
.
If the surface of the silver wire
does
not show any signs of
melting , the temperature is too
low .
In the latter two cases, you will need to enter an
offset va-
lue in the Calibration menu. You may either start from the
existing values and move up or down to the correct firing
temperature or
set the offset to zero and start afresh.

Calibration using a silver wire test
The precision of the
temperature control
has been
precisely calibrated at the factory. Environmental factors,
however,
may cause the selected temperature and the
actual temperature
during the firing process to
drift apart
over time . This can be counteracted by calibrating the
unit and entering a calibration offset. Proceed as follows:
1. Turn on the Multimat
®
Easy (see “Turning on the unit/
Starting a firing program” ).
2. Preheat the firing chamber to a pre-heating temperature
of 650°C over a pre-heating time of 60 minutes.
3. While waiting, insert the silver wire into the wire carrier
(see “Optional accessories” )
4. Open the firing chamber and centre the white carrier on
the firing base.
5. Start the calibration program (see
“Silver wire calibration
program” ) if you already saved it. Allow the program to
run to the end.
