Measurement of leakage current
Display range
0...ILmax

ILmax – maximum current at short circuit of leads,

resolution and units result from the measurement range of individual insulation resistance.
Low-voltage measurement of continuity of circuit and resistance
Measurement of continuity of protective conductors and equipotential bondings with 200 mA
current
Measuring range according to IEC 61557-4: 0.10 ...999 
Display range
0.00 ...19.99
20.0 ...199.9
200 ...999

Voltage at open terminals: 4 V...24 V

Output current at R < 2: I

Compensation of test leads resistance

Measurements for both current polarizations.

When the range is exceeded, the device displays "> 999 Ω" message
