4. Preparation for measuring operating
* Test the voltage tester on a known source.
The " " LED will light on when there is a voltage over 50 V,
*
even if the battery is low or if the battery has been removed.
* Warning: To avoid electric shock, disconnect the test leads
from any source of voltage before turn on the self-check test
function.

* Hold together the two probes L1 + L2 and short them. The
display will illuminate, the audible signal sounds and the LED
for the continuity test lights on. The LEDs for the low
impedance test and the single-pole phase test are off.

* Caution: To avoid electric shock, disconnect the probes from
the power source before you run the auto-test function.
When press "Auto-Test"- button, all voltage LEDs must be on,
*
also the continuity test's LED and the buzzer sound. This
shows the self-test was done.
4.1. Operation
Voltage Test
* Connect both test probes with power source.
* As from a voltage of >6 V (P 1090) resp. >12 V (P 1095) the
voltage tester switches on automatically.
* The voltage is displayed via LCD-display (P 1090) resp. LEDs
(P 1095).
For AC voltages the "AC"-symbol is displayed in the LCD-
*
display (P 1090) resp. the AC-LED is illuminated (P 1095).
For DC voltages the "DC"-symbol is displayed in the LCD-
*
display (P 1090) resp. the "-DC or +DC" LED is illuminated
(P 1095).
* The voltage measurement value is displayed numerically on
the LCD display (P 1090) or over seven LEDs (12 ~ 690 V)
(P 1095) and shows the applied voltage.
