3 Operation of the calibrator
The test instrument TP 18 200 E is a portable unit for service purposes, as well as for operating and laboratory
tasks.
3.1 Adjustment of the handle
The handle can be adjusted into any required position from vertical to horizontal by pressing the lateral stop
buttons.
3.2 Operating position
To guarantee an optimal temperature distribution in the heating block, the normal operating position for the
instrument is the upright position
3.3 Adapter sleeves
It has to be made sure that the heat transmission resistance between the heating block and the test piece
(thermometer, temperature sensor, temperature switch) is as low as possible. Therefore it is necessary to use
exactly adapted pockets. The right bore is the outer dameter of the device under test + 0.5 mm.
3.4 Control of temperature sensors
For the test of temperature sensors a separate temperature measuring unit is required for the connection of the
test piece. By comparing the temperature of the external measuring unit with the block temperature you get an
information about the status of the test piece. Please note that it takes a short time until the test piece has
accepted the temperature of the block.
