1st: Comp Ext/Ice
An external temperature test point acts as a reference, e.g. an
ice bath or another reference thermocouple with a temperature
of 0° C, connected with the closed end to the measuring point,
and the reference put into the ice bath. The closed end of the
thermocouples can be connected with standard measurement
cables to the terminals of the HM8112-3.
2nd: Comp PT-Front
The temperature measured with a platinum sensor is the re-
ference for the measurement used with the thermocouples. If
several thermocouples will be attached to the HM8112-3 via a
scanner, the use of the ice bath would be necessary for each
thermocouple. To overcome this, the ambient temperature or
even a source with a constant temperature is taken as the refe-
rence (e.g. ice bath, heated reference). If "PT-Front" is seleced
the function ϑPT will be activated. Now

temperature is measured with a platinum sensor and assumed

rement the PT-sensor can stay connected to the thermocouple.
For 4-wire measurement it has to be disconnected and replaced
by the connection of the thermocouple.
3rd: Comp 23° C/ °F
A temperature of 23° C is specifi ed as reference. For measure-
ments of high temperatures the resulting measurement error
can be neglected, unless the open end of the thermocouple
is on the level of the ambient temperature. The ambient tem-
perature should be about 23° C.
