Service Hint - Ivoclar Vivadent Programat CS4 Operating Instructions Manual

3. Press START. The furnace head is automatically closed and the
calibration program started.
4. After the end of the program, carefully remove the temperature
control ring and allow it to cool to room temperature on the
cooling tray.
5. Place the temperature control
ring on an even surface and
determine the exact diameter
using the slide gauge.
Make sure that the temperature
control ring is flush with the
two arms of the slide gauge.
Conduct the measurement in
the area where the diameter is
the smallest.
6. Find the measured diameter in the conversion table and read off
the corresponding temperature. Only if the deviation is more than
10 °C must the furnace be readjusted.
7. If the temperature difference is higher than 10 °C the correction
value can be transferred to the furnace with the help of the
-/+ keys. Each keystroke changes the furnace temperature by 1 °C.
The correction value must be added to the current temperature of
the furnace. Once the desired correction value has been entered,
the program can be closed by pressing the ESC key (71).
Calibration is now complete. Close the furnace head or select a
program.
Make sure that the temperature control ring with the
stamp "MTH" is used. The use of an incorrect
temperature control ring may damage the sinter tray.
7.7 Service hints
When the Service Hint appears for the first time (Hint 1700),
2 years have passed or the heating elements have been in use for
more than 1200 firing hours. For this reason, Ivoclar Vivadent
recommends a maintenance and service procedure. After the
acknowledgement of the Service Hint, Hint 1700 will appear again
after 12 months. The message can be turned off under Settings
(see 5.6.1).
