  THE FOLLOWING PROCEDURE IS TO BE               
PERFORMED BY QUALIFIED PERSONNEL ONLY
 
 
1.  With the oven empty, clamp the thermocouple sensor in the center

door gasket and close the door. 
 
b.  Plug the sensor into the Pyrometer. 
 
2.  Turn the OVEN POWER (V.01) switch to ON.  Turn the FAN 
 switch 
(V.02)

HI
 
a.  Rotate the TIME control (V.06) until the time digits (V.05B) on 
 
 
the display read "60:00".

temperature display reads between 370º and 380º, the calibration 
 
is satisfactory.  Otherwise:

  display 
read 
"00:00". 
 
b.  Rotate the TEMP control until the temp digits (V.05A) display 
 
 
between 400º and 500º.
