If Zmax is turned on, consecutive measurements are compared. The
secondary display shows the maximum Z
L
(or Z
I
if F1 = L-N) value until
Zmax is turned off. The Zmax value is saved when you save the test result.
If you change the location fields a, b, or c before you save, the actual test
result is the new Zmax.
Note
RCDs in the system will trip if you use L-PE.
7. Connect the leads in a single-phase test to the system live and neutral. To
measure line-to-line impedance in a 3-phase system, connect the leads to
two phases.
8. Press and release . If Auto Start (Power-on option: + up ) is
turned on, the test starts automatically as soon as the mains voltage is
detected and the required test leads are connected.
Wait for the test to complete.
• The primary display shows the line impedance.
• The secondary display shows the Prospective Short Circuit Current
(PSC).
9. If Zmax is turned on, press the down to show the Zmax value in the
secondary display.
Use the connection shown in Figure 7 for a 3-phase 500 V system
measurement.
