Temperature Measurement; Measurement With Thermocouples, Temp Tc - Gossen MetraWatt METRAHIT ENERGY TRMS System Multimeter Operating Instructions Manual

5.5 Temperature Measurement

Temperature measurement is performed with a type K thermo-
couple or a type Pt100 or Pt1000 resistance sensor (accessory,
not included) which is connected to the voltage input.
Refer to section 6.4 regarding selection of the temperature unit of
measure.

Ð Set the rotary switch to "Temp
Note
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
FUNC | ENTER key in order to change to the other measuring
function.
Ð Either the internal reference junction or an external reference
temperature can be specified as the reference temperature
(see section 6.4.3). Type ("I." for internal or "E." for external) and
temperature of the selected reference junction appear at the
right-hand auxiliary display during measurement.
Note
The internal reference temperature (temperature of the
internal reference junction) is measured by a temperature
sensor inside of the instrument. This may deviate somewhat
from room temperature as a result of internal heat-up, or
moving from warmer to colder surroundings or vice versa.

Note
After previously performing a 10 A current measurement,
the measuring instrument should be allowed to cool down
for 30 minutes before performing measurements with ther-
mocouples, in order to assure that the specified accuracy
levels are achieved.
