3.5 Test programs
3.5.1 Test program DeTrey / Ceramco / External
These test programs will give you a first impression of all program functions the
Multimat
®
Touch can offer. Please also see section 6. Choose one of the programs that you
think you might most likely work with (DeTrey for Europe, Ceramco for USA, External for
competitor’s porcelain).
3.5.2 Start a test program
1. Open the muffle (lift) with the arrow up “$” button on the numeric key pad.
2. Touch sensor button "start/stop".
The firing chamber will be open while this sequence is in progress.
When the low temperature is reached, the program sequence starts with the first program
stage.
Drying
During this stage the muffle (firing chamber) will move downward in a step by step fashion,
and the program curve will be generated on screen in relation to time. Underneath this
program section, the respective time period will be visibly counted down to zero.
The vertical lift of the firing chamber is 150 mm in the normal case and during pressing 158
mm. The firing chamber is closed at 0 mm. The firing chamber is in its upper end position at
150 mm (pressing: 158 mm). The standard drying position is at 80 mm. The firing chamber
moves during drying in 9 uniform steps from its upper end position into the standard drying
position. The standard drying position 80 mm and the 9 steps are values preset in the
factory. The end position and the steps can be changed within these values (cf. 6.13 Change
standard drying position and steps). We recommend retaining these settings if there are no
urgent reasons to do otherwise.
Preheating
The firing chamber will move from its last drying position into the preheating position, and the
preheating time period will be visibly counted down to zero.
Vacuum time controlled (Dentsply DeTrey firing method)
When the preheating time period has expired, the firing chamber will close, the vacuum
pump will be activated and evacuate the firing chamber until the preset vacuum pressure is
reached.
After starting, the furnace will switch
over automatically to the program
sequence screen.
The status line above the
temperature/time graphic is showing
the actual program status and the
complete remaining time.
The program starts by initiating a
heating sequence from the preset
basic/idle temperature to the required
low temperature.
