5.5 Temperature Measurement
Temperature measurement is performed with a type K
thermocouple (accessory, not included), which is connected to
the voltage input. Alternatively, a Pt100 or Pt1000 resistance
thermometer can be used with the METRAHIT⏐X-TRA⏐OUTDOOR .

Note
METRAHIT⏐X-TRA⏐OUTDOOR only:
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 if required.
➭ The reference temperature is measured at the internal
reference junction (see parameter “1tEMP ” in chapter 6.3
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 be somewhat above room
temperature 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.
