Isc factor
[0.20 ... 3.00]
Default value: 1.00
Short circuit current Isc in the supply system
is important for selection or verification of
protective circuit breakers (fuses, over-
current breaking devices, RCDs). The value
should be set according to local regulative.
Earthing
system
[TN/TT, IT]
Terminal voltage monitor and measuring
functions are suited to selected earthing
system.
In some measuring functions the results and
parameters are suited to the selected system.

IEC 60364-4-41 TN/IT,
IEC 60364-4-41 TT,
BS 7671,

Length Unit
[m, ft]
Length unit for specific earth resistance
measurement.
Ch1 clamp type
[A 1018, A 1019, A1391]
Model of current clamp adaptor.
Range
A 1018:[20 A]
A1019: [20 A]
A 1391: [40 A, 300 A]
Measuring range of selected current clamp
adaptor.
Measuring range of the instrument must be
considered. Measurement range of current
clamp adaptor can be higher than of the
instrument.
