4.6. 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

"L" are always displayed, however the rotary direction can only

be determined within a thee-phase system, here the instrument

indicates the voltage between two external conductors.

• Connect the instrument Red Test Lead (L2+) with the supposed

phase L2 and the Black test lead (L1-) 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.

• The test result table is as follows:

• Effective for voltages greater

than 80Vrms.

• The Tester measures low ohm resistances between 1 and 1999

at a resolution of 1 . Ω

• When you do a Resistance test make sure the UUT (Unit under

test) is not live.

• When you do a continuity test make sure the UUT (Unit under

test) is not live.

• The continuity test is only possible when batteries are installed

and in good condition, a signal sound is audible for continuity and

the LED for continuity LED is illuminated.
