(-0 % / +15 %) of reading
The accuracy is valid if mains voltage is stabile during the measurement and PE
terminal is free of interfering voltages.
Trip-out measurement is not available for I

Specified accuracy is valid for complete operating range.
9.4 Fault loop impedance and prospective fault current
9.4.1 No disconnecting device or FUSE selected
Fault loop impedance
Measuring range according to EN61557 is 0.25 9.99k.
(5 % of reading + 5 digits)
Prospective fault current (calculated value)
Consider accuracy of fault
loop resistance
measurement
The accuracy is valid if mains voltage is stabile during the measurement.
