In order to guarantee excellent temperature sta-
bility, the cycle time of the controller is set to low
and the control output is addressed on a regular
basis.

Testing temperature sensors
A separate temperature measuring instrument connected to the test specimen is required to
test the temperature sensors. By comparing the temperature displayed at the external meas-
uring instrument with the reference temperature it is possible to assess the status of the test
specimen. Remember that the test specimen requires a short period of time until it absorbs
the temperature of the metal block or liquid bath.
The internal references are set to normal when operating the multifunction calibrator, the mi-
cro-bath, the dry block and the infrared function; the selector switch should be turned to int.
Ref.
If operated as a surface temperature calibrator then an external reference is used. Please
connect this to the mini-DIN socket and turn the selector switch to ext. Reference.
CAUTION! Incorrect results!
It is not possible to calibrate earthed thermal elements, because the heating block is
earthed and any measurement would produce incorrect results.
Control occurs via PID algorithm
