Measuring Range Resolution Accuracy Overload Protection
2M Ω 0.01M Ω ±2% ±2 digits 300 V AC/DC
20M Ω 0.1M Ω ±5% ±2 digits 300 V AC/DC
200M Ω 1M Ω ±10% ±2 digits 300 V AC/DC
Test voltage 500VDC at 1mA,
<750VDC for o/c
Test voltage accuracy +20%, -0%
Test current <2mA for s/c
The maximum number of insulation tests, with a duty
cycle specified by BS EN 61557-2 Section 6.7, is 2000
repetitions.
7.3 IEC lead test
The IEC lead test is a sequence of earth continuity
measurement (section 7.1) - insulation resistance
measurement (section 7.2) - Live/Neutral checks for o/c,
s/c and crossed conductors in the IEC lead.
Test voltage 9 VDC
Test duration 10 seconds
7.4 Touch current measurement
Measuring Range Resolution Accuracy Overload Protection
3.5mA 0.01mA ±10% ±2 digits (5° - 40°) N/A
±15% ±2 digits (0° - 5°)
Test voltage mains supply @ 230V -
15%/+10% @ 10A max
Frequency 50Hz ±1%
Test duration 2 seconds minimum
Frequency response IEC 61010-1 Annex A.1
The test is disabled when phase-neutral (PN) or phase-
earth (PE) voltage is not at mains potential or a voltage of
40 V AC or greater exists between neutral-earth (NE).
