Page 10: Operation
Auto-calibration prevents the reduction in accuracy when measuring very low currents. It compensates the effects caused by ageing, temperature and humidity changes etc. A new auto-calibration is recommended when the temperature changes by more than 5 °C.

Page 13: Dc Vs. Ac Testing Voltage
DC vs. AC testing voltage Testing with a DC voltage is widely accepted as being useful as testing with AC and / or pulsed voltages. DC voltages can be used for breakdown tests especially where high capacitive leakage currents interfere with measurements using AC or pulsed voltages. DC is mostly used for insulation resistance measurement tests. -

Page 15: Polarisation Index
POLARISATION INDEX The purpose of this diagnostic test is to evaluate the influence of the polarization part of insulation (Rpi, Cpi). After applying a high voltage to an insulator the electric dipoles distributed in the insulator align themselves with the applied electrical field. This phenomenon is called polarization. As the molecules polarize, a polarization (absorption) current lowers the overall insulation resistance of the material. -
Page 16: Withstanding Voltage Test
Withstanding voltage test Some standards allow the use of a DC voltage as an alternative to AC withstanding voltage testing. For this purpose the test voltage has to be present across the insulation under test for a specific time. The insulation material only passes if there is no breakdown or flash over. Standards recommend that the test starts with a low voltage and reaches the final test voltage with a slope that keeps the charging current under the limit of the current threshold. -
