TEL-TRU THERMOMETER CALIBRATOR CARE AND USE INSTRUCTIONS
Your Tel-Tru Thermometer Calibrator has been designed to provide many years of trouble-free service. You can help
ensure that your calibrator will provide you with this trouble-free service through careful use and basic maintenance
tasks. Set-up of all Tel-Tru Thermometer Calibrators should be done on a at, clean, dry surface, in a well ventilated
area. Set-up of the “cold” and “multi-temperature” Tel-Tru Thermometer Calibrators should be done in a manner that
provides maximum air circulation around the unit.
• Ideal ambient operating temperature should range
between 65°F and 85°F.
• Avoid setting the unit on surfaces that may restrict
air ow, such as carpet and towels.
• Allow clearance around the unit. It is better if the
unit is not “stacked” with other equipment.
• The fan vent at the rear, and the exhaust vent
on the side of the unit must be kept clear.
• The air lter for the fan vent should be cleaned
regularly (DO NOT remove lter screws, the lter
guard can be “popped out” with your ngers).
• The tilt stand may be used to improve air circulation.
PROBE IMMERSION REQUIREMENTS
For best results, the sensing area of the probe must be
inserted completely into the Temperature Control Zone.
The minimum immersion depth is dependent on the
thermometer type. Check the manufacturer’s user
manual of your thermometer for the correct immersion
length.
