Figure 26: Connection of test leads to tested wiring for LOOPL/PE measurement
7) READY message will appear when mains voltage UL/N (LOOP L/N) or UL/PE (LOOP L/PE) within
100 265 V or UL/L (LOOP L/L) within 100 460 V is present. Carry out the measurement by
pressing the START button.
8) Test result (loop impedance) will be displayed in green colour equipped with green symbol and
with beep-beep sound if measured/calculated ISC corresponds to entered limit mode and other
entered parameters. If measured/calculated ISC does not correspond to entered limit mode and
other entered parameters the result will be displayed in red colour equipped with red symbol
and with longer beep sound. See the display outlook with test result on the figure 22.
9) Save the test result by pressing the SAVE hard button twice, for further instructions see the
“MEMORIZING EXAMPLE” section.
10) Press the EXIT hard key to clear displayed result, actual input voltage UL/L or UL/N or UL/PE will
start to be displayed again.
CAUTION
In case voltage UL/N (LOOP L/N measurement) or voltage UL/PE (LOOP L/PE
measurement) within required range 100 265 V is present at L/N/PE test
terminals (also displayed) but there is no READY message displayed, check if
energizing socket is correctly earthed!
In case voltage U
L/L (LOOP L/L measurement) within required range 100 460
V is present at L/N test terminals (also displayed) but there is no READY
message displayed, check if energizing socket is correctly earthed!
If limit mode STD is selected (result is not evaluated), then the result will be
displayed in white colour.
The following specific information can be shown on the display during the measurement:
Information displayed Description
VOLTAGE OUT OF RANGE
Input voltage UL/N or UL/PE out of required range 100
265 V (L/N or L/PE measurement) or out of required range
173 460 V (L/L measurement) after pressing the START
key.
FUSE F3!
Fuse F3 is blown.
HOT!
Internal load is overheated.
Wait to cool it down!
MEASUREMENT FAILED!
Input voltage failed during the measurement (disconnection
of test leads, installation fuse tripped etc.)
