* The polarity of the voltage displayed refers to the instrument
test probe (L2).
Single-pole phase Test
* The single-pole phase test is only possible when batteries are
installed and in good condition.
* The single-pole phase test starts at an AC voltage of approx.
100 V (pole >100 V AC).
* When using single-pole phase tests to determine external
conductors the display function may be impaired under certain
conditions (e. g. for insulating body protective equipment on
insulation locations).
* The single-pole phase testing is not appropriate to determine
whether a line is live or not. For this purpose, the double-pole
voltage test is always required.
* The LED is illuminated in the display.
* Probe "L2" with voltage source connected to the single-pole
phase test LED lights. Using the P 1090 simultaneously the
LCD display lights, but it does not display any voltage value.
So, please perform the two-pole voltage test afterwards.
Continuity Test
* The continuity test is only possible if there are batteries with
sufficient power.
* Continuity test works only on non- active conductors.
* Use both probes to measure the conductor.
* Continuity test will only work with circuit resistances
<200 kΩ (P 1090) / <300 kΩ (P 1095).
* A continuous beep sounds and the corresponding LED lights.
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 3 - phase system. The instrument
indicates the voltage between two external conductors.
