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 ° F and should be regularly calibrated
by a third party. Never use alcohol or mercury-based thermometers!
Cascade Sciences CVO ovens do not normally require
calibration. Should your SOP or quality program require
calibrations, follow this guideline.
Temperature calibrations match the temperature display to
the actual shelving temperature inside the oven chamber.
The actual shelving temperature is supplied by a reference
sensor device. Always calibrate to the industry or regulatory
standards required for your application.
Suggested Temperature Calibration Set Up
Continued on 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 end must be in direct
contact with the shelving . Place the probe on the
shelving as close as possible to the geometric
center of the chamber.
•
The probe may be taped to the shelves
using heat-resistant non-stick tape. Use
the tape to secure any loose wiring.
4.
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.
