5.6 Rotary Field Indication
• The voltage testers are equipped with a double-pole rotary field indicator.
• The rotary phase indication is always active. The symbols "R"or " I.:' are
always displayed. However, the rotary direction can only be determined
within a three-phase system. Here, the instrument indicates the voltage
between two external conductors.
• Connect the instrument test probe with the supposed phase L2 and the
handle test probe with the supposed phase L1.
The voltage and the rotary field direction are displayed. "R" signifies that
the supposed phase L1 is the actual phase L1 and the supposed phase
L2 is the actual phase L2.
"L" signifies that the supposed phase L1 is the actual phase L2 and the
supposed phase L2 is the actual phase L1.
When re-testing with exchanged test probes the opposite symbol has to
be illuminated.
