5. Operation:
5.1 Preparing the test
1
Prior to every test, please ensure that the instrument is in perfect condition:
2
• For example, keep an eye out for a broken housing or leaking batteries.
• Always carry out a function test before using the voltage tester, see below.
3
• Check that the instrument is functioning properly(for example at a known voltage
4
5
source)before and after every test.
6
• If the safety of the user can not be guaranteed, switch off the instrument and
7
secure it to prevent unintentional usage.
8
Carrying out a function test
9
Connect the voltage tester probe tips for 4 to10 seconds and then disconnect.
10
With the exception of the LED for low impedance test, all LEDs should light up.
11
12
All segments are illuminated on the LCD display.
The functioning of the voltage detector is to be checked shortly before andafter
13
use by using the testing element. If the indication "not ready"appears or if
theindication of one or more steps fails, or if no functioning is indicated, the
14
voltage detectoris no longer to be used.

5.2 Voltage Test
16
• Connect both test probes with power source.
• As from a voltage of >6V the voltage tester switches on automatically.
• The voltage is displayed via LEDs.
17
The different indicating signals of
the voltage detector (including the
ELV limit indication)are not to be used
for measuring purposes.
• The voltage is also shown on the
LCD display.
• For AC voltage, the "AC" is illuminated;
For positive voltage, the "+" is illuminated;
For negative voltage, the "-" is illuminated.
• In the case of DC voltage,the polarity of the indicated voltage relates to the
voltage tester probe tip
• Once the safety extra-low voltage (50V AC /120V DC)is reached or exceeded,
the "
" is illuminated, in the event of no battery power or main circuit failure,
and an acoustic signal is emitted.
