mercury thermometer in the center of the oven.
B. Turn the oven control dial to 400°F (202°C) to allow the
oven temperature to stabilize. Allow the oven to cycle
twice before taking a test reading.
C. Check the temperature reading when the control cuts
down to bypass. If the temperature does not read within
15°F (5°C) of the dial setting recalibrate as follows.
D. Remove the control dial, making sure not to disturb the
setting.
E. Hold the calibration plate and loosen the two calibration
lock screws until the plate can be rotated independently
of the control.
F. Turn the calibration plate until the temperature indicated
on the plate corresponds with the reading of a test
instrument. Hold the plate and tighten the screws fi rmly.
G. Repeat the temperature reading check when the control
cuts down to bypass to make sure the correct adjustment
has been made.
