2.2.1 Sub-menu Measurement Settings
The option of Measurement settings consists of:
mains rated voltage,
network frequency,
manner of presentation of short-circuit loop result,
type of mains for the tested object,
system of units,
memory settings (auto-incrementing memory cells).
Before the measurements select the type of mains from which the tested object is powered.
Then select the mains rated voltage U
n
(110/190 V, 115/200 V, 127/220 V, 220/380 V, 230/400 V or
240/415 V). This voltage value is used for calculating the values of prospective short-circuit current.
Determination of network frequency that is the source of potential interferences is necessary in
order to select a proper measuring signal frequency in resistance-to-earth measurements. This selec-
tion ensures optimum interference filtering. The meter is designed for filtration of interferences gener-
ated by 50 Hz and 60 Hz networks.
