CALIBRATION INDICATOR
All Ugin’Dentaire furnaces have been subjected to IPTS 68 ( International Practical
Temperatue Scale, 1968 ) temperature testing using a Eurotherm 239-type millivolt
generator.
You can, however, modify the furnace settings by means of digital calibration.
This easy-to-use function applies to all furnace programs.
When programming the final temperature, press the standby key Standby.
The calibration indicator lights up and the parameters display shows the factory preset
calibration number,
5
.
This setting assures satisfactory operation for a new muffle.
If the firing results indicate an overly high baking temperature
- increase the setting :
6
= 1 point, or : -10°c
7
= 2 points, or : -20°c
if the firing results indicate an overly low temperature
- decrease the setting :
4
= 1 point, or : + 10°c
3
= 2 points, or : +20°c
You can check the accuracy of the temperature setting by running a silver test.
