R-PE(loop) measurement procedure
(For reference measurement procedure see chapter
G.3.3 Fault loop impedance and
prospective fault current
)
Select the
CONTINUITY
function.
Set sub-function
R-PE(loop)
.
Enable and select
Fuse I
(optional).
Select maximum
touch voltage Uc
(optional).
Connect
test cable to the instrument.
Tested installation must be in normal operating condition with mains supply.
Connect
test leads to the tested socket (see
figure
G.6
).
Press the
TEST
key for measurement.
After the measurement is finished
store
the result (optional).
