ALIBRATE THE
T
EMPERATURE DISPLAY
Note:
A calibration reference device must be purchased separately. For best results, use a digital device
with thermocouple probes. The device must be accurate to at least 0.1
°
C and should be regularly calibrated
by a third party.
Never use alcohol or mercury based thermometers.
Temperature calibrations match the temperature display to the actual
shelving temperature in the oven chamber. The actual shelving
temperature is supplied by a reference sensor device. Calibrations
compensate for drifts in the controller as well as those caused by the
natural material evolution of the sensor probe in the heated oven
chamber. Calibrate as often as required by your laboratory or
production protocol, or regulatory compliance schedule. Always
calibrate using industry or field standards.
The manufacturer recommends calibrating at the constant set point
temperature of your application or at the median of your multi-step
set heating profile.
Suggested Temperature Calibration Set Up
Continued next page
1.
Introduce a thermocouple probe from a reference
device into the oven chamber using a feedthrough
secured to the KF-25 port on the back of the oven.
•
Place at least 12 inches (305 mm) of
thermocouple wire in the chamber to prevent
heat sinking outside temperatures.
2.
Use the KF-25 clamp included with the oven to secure
the feedthrough and probe, sealing the port.
3.
The thermocouple probe ends must be in direct
contact with the shelving.
•
The probe may be taped to the shelves using
heat-resistant non-stick tape. Use the tape to
secure any loose wiring.
4.
VACUUM GAUGE
Evacuate the chamber to the vacuum level of your
application or baking process.
•
The chamber must be under vacuum in order
to perform an accurate temperature
calibration.
