7.5 Protective earth conductor current
measurement
Measuring Range Resolution Accuracy Overload Protection
19.99mA 0.01mA ±5% ±2 digits N/A
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
(from 40Hz)
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).
7.6 RCD test
Test current 30mA r.m.s
Test current accuracy +5%, - 0%
Test duration 500ms maximum if RCD
does not trip
Trip time accuracy 0mS to 40mS, ±2mS
41mS to 500mS, ±5mS
The test is disabled when phase - neutral (PN) or phase
-earth (PE) voltage is not at mains potential or a voltage
of 40 VAC or greater exists between neutral - earth (NE).
7.7 Zs test
Measuring Range Resolution Accuracy Overload Protection
19.9 Ω 0.1 Ω ±10% ±2 digits N/A
199 Ω 1 Ω ±10% ±2 digits N/A
Test current Such that it will not trip a
30mA RCD
Test voltage 230VAC +10%, -15%
The test is disabled when phase-neutral (PN) or phase-
earth (PE) voltage is not at mains potential or a voltage of
40VAC or greater exists between neutral-earth (NE).
