Single Pole Phase Test
• When carrying out single-pole phase test, touch the contact electrode (6) and
connect the inst test probe to the unknown source.
Note: gloves or other protective clothing may impair this function by preventing
connection to the contact electrode.
• An audible tone is generated to indicate the phase.
• Single pole phase test starts at 100V AC.
Note:
The single pole phase test is not appropriate to determine whether a line is live
or not. Use the double pole voltage test for this requirement.
Continuity Test
Note: Ensure the circuit to be tested is not live and all capacitors have been
discharged. Perform a double pole voltage test to check before continuing.
• Connect both test probes across the item under test.
• An audible tone is generated and the Rx/Ω LED is illuminated to indicate
continuity.
Rotary Field Indication
• The rotary phase indication is always active. The symbols ◄L R► are always
displayed, however the rotary direction can only be determined within a three-
phase system.
• Connect the inst test probe with the phase L2 and the ground test probe
with the phase L1 for example.
• The instrument indicates the voltage between two external conductors.
• Touch the contact electrode (6) and the voltage and the rotary field are displayed.
• R► signifies that the assumed phase L1 is actually L1 and that assumed phase L2
is actually L2 - right rotary field.
• ◄L signifies that the assumed phase L1 is actually L2 and that assumed phase L2
is actually L1 - left rotary field.
• When re-testing with exchanged test probes, the opposite symbol will be
illuminated.
