Other items:
Result converted to insulation resistance at reference
temperature. 10 different temperature compensation
tables can be selected, according to insulation material
of measurement object. Reference temperature: 20¢ªC
or 40¢ªC by default, setting can be changed.
PI: Polarization Index
DAR: Dielectric Absorption Ratio
After insulation resistance measurement has started,
calculation is performed using two resistance values
obtained at prescribed time intervals.
Measurement of insulation resistance while raising
voltage at specific intervals. Two voltage step patterns
can be selected.
STEP 2.5kV : 500V¨1kV¨1.5kV¨2kV¨2.5kV
STEP 5kV : 1kV¨2kV¨3kV¨4kV¨5kV
Voltage application time for each step: 30 s./1/2/5 m.
Manual recording: store up to 100 data , Data type:
standard measurement data/ temperature compensation
data/step voltage test data, Data logging: store
measurement value at preset intervals, available for
insulation resistance measurement only, Number of
data: 10, Number of logging instances: 360 times per
data, Recording interval: 15/30 s /1/2/5m, Data content:
date, time, measurement interval, temperature, set
voltage, actual output voltage × times, resistance ×
times, Additional functions: write mode, read mode, all
