Select “Quick QC Check” by pressing the
Selector
Knob
OR pressing the Next button.
Entering a Temperature to Check
The Pro 200 is now ready to raise the temperature to any
setting you desire and hold the temperature constant for up
to 40 minutes. Select the specific temperature by rotating
the
Selector Knob
clockwise for increased temperature
or counterclockwise for decreased temperature. Once
rotated to the desired temperature press the

inward to got to the newly selected temperature.
Pro Cal Furnace
Change Idle Temp
>Roll Knob 250 C
Press Knob = GoTemp
NOTE: YOU CAN SELECT A NEW STABLE IDLE
TEMPERATURE AT ANY TIME BY PRESSING THE LAST
BUTTON ON THE PRO 200 ROLLING THE SELECTOR KNOB
TO A NEW TEMPERATURE VALUE AND THEN PRESSING THE
SELECTOR KNOB AGAIN. THE PRO 200 WILL TRANSITION TO
THE NEW VALUE. YOU CAN REPEAT THIS AS MANY TIMES
AS YOU WISH. IF YOU ARE DONE WITH THE PRO CAL QUICK
CHECK ACTIVITY YOU CAN PRESS THE MAIN MENU BUTTON
TO EXIT THE PRO CAL MODE AT ANY TIME AND THE PRO 200
WILL AUTOMATICALLY REVERT BACK TO THE PRIMARY IDLE
TEMPERATURE YOU DESIGNATED WHEN YOU ORIGINALLY
SETUP YOUR FURNACE FOR THE FIRST TIME.
The Pro Cal “Idle” temperature is NOT the same as the Idle
Temperature you selected from the Special Functions
Menu. The Pro Cal is a separate operating mode.
Allow Stabilization Time
It is suggested that a period of at least 15 – 20 minutes is
allowed for stabilization time before manually recording
the value on the Instrument box LCD display to insure a
stable reading.
What to do with the Results
It is suggested that you survey three temperatures
(minimum) to look for overall trends, and to help you
decide which type of correction method best fits your
available time and addresses the current situation the best.
The three primary temperatures suggested are:
Celsius Value
Fahrenheit Value
850°C
1562
1000°C
1832
1150°C
2102
These are the temperatures used by the Full Calibration
method.
For example, if you surveyed the three temperatures
above and when the furnace display said 850°C the LCD
display on the Instrument box read 851°C.
AND at 1000°C on the furnace display the Instrument box
read 1002°C.
AND at 1150°C on the furnace display the Instrument box
read 1151°C.
All three being slightly higher on the Instrument box
indicates that the furnace is slightly OVERFIRING across
the board. Since the Over-firing values are not more than
3 degrees C above the nominal target temperatures, a
Full Calibration run IS NOT INDICATED. The fastest and
easiest way to proceed from here is to enter a 1 or 2 degree
OVERFIRE into the
Special Functions
High Fusing Adjust
section of the Pro 200 software.
The procedure for doing so follows in the next section of
this manual.
One thing to remember about using the
Special Functions
Menu selected Fusing Adjustment entry is it affects all
User Program Firings equally, every single one of them.
Conversely, if you had found, in the QC Survey above:
Furnace Display
Instrument Box Display
850°C
850°C
1000°C
1001°C
1150°C
1150°C
Only a single temperature range
is over-firing.
You would
NOT want to use the Special Functions High Fusing
Adjust entry method
to register the Over-firing at the
Quick Check Survey
