Temperature Measurement; Measurement With Thermocouples, Temp Tc - Gossen MetraWatt METRAHIT PM TECH Operating Instructions Manual

7.5 Temperature Measurement

Temperature measurement is performed with a type K
thermocouple (accessory), which is connected to the voltage in-
put. Alternatively, a Pt100 or Pt1000 resistance sensor can be
used with the METRAHIT PM XTRA / PM TUNE / E
PM TECH / E .

The last selected temperature measurement or the last
selected temperature sensor, i.e. type K or Pt100/Pt1000,
remains in memory and is accordingly displayed. Press the

function if required.
➭ The reference temperature is measured at the internal
reference junction (see parameter "1tEMP " in chapter 8.3
regarding querying).

Note
The internal reference temperature (temperature of the inter-
nal reference junction) is measured by a temperature sensor
inside of the instrument. This may deviate from room tem-
perature as a result of internal heat-up, or moving from
warmer to colder surroundings or vice versa.
➭ Connect the sensor to the two accessible jacks. The instru-
ment displays the measured temperature using the selected
unit of measure.
