5.4.4. Oven Zone Calibration
The Control instrument has been factory-tested and calibrated. Under normal operating
conditions, recalibration should not be necessary. However, to recalibrate the Control Instrument
for a specific operating condition, follow the instructions below.
Warning!
Changing program parameters alters the function of the Control.
Proceed carefully and fully understand each parameter before
changing that parameter.
1.
Required Equipment: Temperature measuring device with a compatible temperature sensor.
2.
Verify that
bS
(PV Bias) programmed in the Control instrument is set to 0. For more
information on programming parameters refer to Section 5.4.2.1.
3.
Locate the temperature sensor of the temperature measuring device at the center of the
chamber.
Load the chamber with a standard amount of product to
simulate a specific operation condition.
4.
Operate the oven until it reaches the desired operating temperature and the Control instrument
is regulating.
a.
It will take several minutes for the unit to stabilize at the controlled temperature.
b.
Allow at least 30 minutes of operation at the stabilized temperature before proceeding.
5.
Subtract the average controlled temperature (value appearing on the Control instrument
display) from the actual oven temperature (value appearing on the temperature measuring
device display).
a.
Note that the Control instrument and the temperature sensing device must be in the same
scale (
C or
F).
