4.4.2 Temperature compensation
NOTE: Temperature compensation is only available in IR sub-mode. Temperature compensation is off by default.
Before an insulation resistance test can be carried out with
temperature compensation enabled, the temperature of the unit
under test must be established.
For this procedure Refer to 14.1.4 Temperature compensation on
page 72
If a temperature measurement hasn’t been made, the left of the
secondary field will show -- °C.
If a test is attempted the unit will display Temperature missing.
