4.2.9 Temperature (K thermocouple)
Special reference conditions:
Internal heating can be caused by:
¾ the measurement of a high current over a long period
¾ overload of the + COM input when the switch is set to the T° position or
Ω
.
In this case, a certain waiting time is needed to return to the specified metrological conditions.
The multimeter must be at room temperature. Otherwise it may take up to 2 hours to return to the specified metrological
conditions. If you do not wait, there will be a temperature offset, because the temperature reference of the cold junction is
slightly altered. When in doubt it is possible to check the measurement of a known temperature (e.g. ambient) using the
thermocouple.

The accuracy announced for external temperature measurement does not take into consideration the accuracy of the K
thermocouple.
There is no upper limit to the temperature display other than the display's 6000 D.
