Only if Methods > Measure > Interval reading is active, you can tap to
switch between these 2 modes.
Displays the temperature.
Tap to perform a temperature check while the meter is in idle state.
: gets the temperature value from the sample automatically.
: taps to change the temperature value used for the current
measurement only.
Displays the information of the endpoint type.
If a user belonging to the Administrator user group is logged in, you can tap
