15. Put the ZONE (new) value into the Product through the
n
front panel or RS-232 port. Table 21 is a list of
temperature setpoints and the RS-232 command and

16. Let the Product soak for 60 minutes for the calibration
points of 700 °C, 1000 °C, and 1200 °C. Let the
Product soak for 120 minutes for calibration points of
300 °C after you put in the ZONE value.
17. Do steps 1 through 5 again to make sure axial
uniformity is equal to or less than the specification or
requirement. If the Product does not satisfy the
specification or requirement, do steps 6 through 16
again with the new axial uniformity values.
To complete the calibration of the Product, do a stability
test, axial uniformity test, and accuracy test to make sure
the Product is equal to or less than the specifications for
each setpoint.
