Insulation Measurement
1
TRMS interference voltage measurement (V
AC+DC
) with 1 M input resistance,
frequency response width: > 65 ... 500 Hz, accuracy: 3% + 30 digits
Short-Circuited Coil Test (only with optional COIL adapter)

TRMS interference voltage measurement (V
AC+DC
) with 1 M input resistance,
frequency response width: > 65 ... 500 Hz, accuracy: 3% + 30 digits
2)
The time value may vary for differnt COIL adapters by up to 10 %. This has no influence whatsoever
if you perform the measurements with the same COIL adapter and compare them with each other.
Inductance measuring ranges of optional COIL adapters:
• COIL adapter XTRA (Z270M): 10 µH up to 5 H
• COIL adapter 50mH (Z270F): 10 µH up to 50 mH
