30-sec insulation resistance
5) Automatic Measurement of Dielectric Absorption Ratio (DAR) and Polarization Index (PI)
When the measurement time reaches the set time of dielectric absorption ratio (DAR), the tester will
automatically calculate and display the DAR value, as shown in Picture 21.
Other time can be set in the "Settings" option to calculate the DAR value.
