5.4.4 Adjustable parameters in the program screen
t – Temperature increase rate
The temperature increase rate defines by how many degrees per minute the furnace heats up.
Value range °C: 10 – 140 °C/min; Value range °F: 18 – 252 °F/min
T – Holding temperature
The holding temperature defines the temperature at which the press process is started.
Value range °C: 100 – 1200 °C; Value range °F: 212 – 2192 °F
H – Holding time
The press process starts once the holding time ends.
Value range: 00:00 – 60:00 (mm:ss)
E – Stop speed
This parameter defines the end of the press process.
For the layering technique, Ivoclar Vivadent recommends a stop speed of 300 µm/min and for the staining
technique a stop speed of 150 µm/min.
– Higher values (stop speed of e.g. 300 µm/min) result in the press cycle being stopped sooner.
– Lower values (stop speed of e.g. 100 µm/min) result in the press cycle being stopped later. Consequently,
the press cycle is prolonged.
Value range: 0 - 10,000 (µm/min)
5.4.5 Adjustable parameters in the Options menu
In addition to the parameters shown in the firing curve, several other options are available that can be activated by
pressing the
[Options]
button. Active options are displayed as icons in the grid next to the
[Options]
button.
The following press program options are available:
Program write-protection
If the program write-protection is activated, the program parameters and program options cannot be
changed. This is to prevent accidental changes to the program.
Setting options: On / Off
B
Stand-by temperature
The stand-by temperature is the temperature to which the furnace heats up immediately after switching
on. The temperature is maintained with the furnace head closed and when no firing or press process is
activated.
In the "Pressing" mode, Programat furnaces feature an automatic stand-by temperature of 700 °C as the
factory setting. The temperature can be individually set for each program.
Value range °C: 100 – 700 °C; Value range °F: 212 – 1292 °F
