Temperature Unit: selection of temperature unit.

Default Probe Temperature: measurement temperature.

 Rc Reference Temperature: reference temperature to which the measurement result must be
referred.
  T for R/2: estimated  T to obtain an insulation resistance / 2.

Calculate   T from Memory: used to calculate   T from 3 stored measurements made using the

same probe at different temperatures (see § 4.5.3).
Maximum Output Voltage: imposes maximum/locking of test voltage.

 Set Default Parameter: default confi guration: reinitializes the instrument with the default values of
all parameters.
Clear Memory: can be used to partially or completely erase stored data (see § 4.5.2).

 V Disturbance / V Output = dlSt factor (see § 3.2 - Important remark).
Buzzer: enabling / disabling of buzzer (keys, measurements, alarms).
