The IR-500 Calibrator is mainly structured by 58 mm diameter target assembly
and dry-well temperature system controlled by a microcomputer. The external
reference thermometer is a metal cone with good heat-conducting ability, on the
surface of thermometer there is a oxide lm with emissivity 0.95.
The IR-500 Calibrator contains a class-A PT100 sensor with a temperature control
system and wind-cold device. The calibrator has rapid heating and cooling
functions and is switchable between °C/°F, which can be used for different
temperature unit calibrations.
The calibrator operates over a range of 50 °C to 500 °C with a temperature display
resolution of 0.1 °C.

Unpack the calibrator carefully and inspect it for any damage that may
have occurred during shipment. If there is shipping damage notify ETI Ltd
immediately.
Verify that the following components are present:
• Calibrator
• Power Cord
• User Manual
Place the calibrator on a at surface with at least 8 inches of free space around
the instrument. The stand may be swung down to raise the front of the
instrument from a horizontal position. Plug the power cord into a grounded
mains outlet (Note: this calibrator has two power specications of one model
NO:220V/AC and 11OV/AC, please make sure the power value is suitable for the
instrument before operation.)
Turn on the power to the calibrator by toggling the power switch on. The fan
should begin quietly blowing air through the instrument and the controller
display should illuminate after 3 seconds. After a brief self-test the controller
should begin normal operation. If the unit fails to operate please check the
power connection.
The heater will start operating to bring the temperature of the calibrator to
the set-point temperature and the display will begin to show the actual target
temperature.
The unit should be used with a secondary certied reference thermometer
(E.g. ETI Reference Thermometer product code 222-055)
Press "UP" or "DOWN" to change the set-point value.
Then press "SET". The calibrator will automatically control the target assembly
temperature to reach the set temperature in the stated time. The red LED
display will indicate the temperature of the target assembly. When the set-point
temperature is changed the controller switches the well heater on or off to raise
or lower the temperature. The displayed well temperature gradually changes
until it reaches the set-point temperature. The well may require 5 to 10 minutes
to reach the set-point depending on the span. Another 5 to 10 minutes is
required to stabilise within ±0.1 °C of the set-point. Ultimate stability may take 15
to 20 minutes more of stabilisation time.
