5 Operation

5.1 Switching on

The device automatically switches on if it detects continuity, an AC

or DC voltage above approx. 6 V, or a live phase on L2.

Alternatively, it can be switched on with the function button.

5.2 Switching off

The device is automatically powered off after 30 s if there is no

signal contacted to the probes.

The torch light switches off after approx. 30 s.

5.3 Self-test

Do not use the device during the self-test.

The self-tests starts if the device is off and both probes L1 – and L2

+ are shorted.

The self-test will start automatically when replacing batteries.

Expected result: All LEDs, all symbols on the display,thebuzzer,

and the vibration switch on for 2 s.

If (some of) the LEDs, or display symbols,orthebuzzer,or

the torch light do not switch on, the device is not safe for use.

Restart the self-test again. If the result is not the expected

result (see above), the device must be removed permanently

from operation and has to be secured against inadvertent use.

If the battery symbol is displayed continuously on the display,

the batteries are empty and must be replaced. See chapter

„Exchange of batteries“.

5.4 Torch light

Pressing the function button will turn on the torch light and after

approx. 30 s it will turn itself off.

When torch light is on, pressing the function button about 6 s will

turn it off.

5.5 Data hold mode

When the data hold mode is active, only the last saved meas-

ured voltage value is shown in the display.

The display will not be updated, even if the voltage under test

changes!

The LED voltage indicators always show the actual voltage

of under test.

After pressing the function button for more than 2 s, the data hold

mode is activated and the display shows the last measured value. A

shortsoundalsoconrmstheactivation.

If data hold mode is active, the screen shows the symbol “H”.

Thedataholdmodecanbedeactivatedbybrieypressingthefunc-

tionbuttonagain.Ashortsoundconrmsthedeactivation.

6 Conducting measurements/tests

6.1 General information

Before and after use, always conduct the self-test and check

that the tester is in perfect working order (e.g. on a known

voltage source).

Measurement category with screwed-on safety cap:

CAT IV 600 V, CAT III 1000 V

Measurement category without screwed-on safety cap: CAT II 1000

V

For tests/measurements of Schuko sockets, the 4 mm test tip adapt-

ers (round pins) are to be screwed onto the test tips.

Put the test tip cover on if you do not work with the device to

prevent injuries and damage to the test tips.

6.2 Voltage test (TRMS) with polarity indication

To determine the absence of voltage, 2 results must be

achieved: No voltage and no indication of polarity.

The voltage indication is battery independent. However,

without batteries the device only has a limited functionality:

If the batteries are empty or if there are no batteries inserted

into the device, only the LED for dangerous voltage lights

up if a voltage of 50 V

AC

/ 120 V

DC

is present.

Therefore, if possible, operate the device with batteries. See

chapter „Exchange of batteries“.

The voltage indication (steps) via LED must not be used as

measurement. It is only an indication of voltage range.

Depending on the internal impedance (internal resistance)

of the voltage detector there will be a different capability of

indicating the presence or absence of operating voltage in

case of the presence of interference voltage.

•Low impedance voltage detectors:

A voltage detector of relatively low internal impedance,

comparedtothereferencevalueof100kΩ,willnot

indicate all interference voltages having an original

voltage value above the ELV level. When in contact

with the parts to be tested, the voltage detector may

discharge temporarily the interference voltage to a level

below the ELV, but it will be back to the original value

when the voltage detector is removed.

When the indication “voltage present” does not appear,

it is highly recommended installing earthing equipment

before work.

•High-impedance voltage detectors:

A voltage detector of relatively high internal impedance,

comparedtothereferencevalueof100kΩ,maynotper-

mit to clearly indicate the absence of operating voltage in

case of presence of interference voltage.

When the indication “voltage present” appears on a part

that is expected to be disconnected of the installation, it is

highlyrecommendedconrmingbyanothermeans(e.g.

use of an adequate voltage detector, visual check of the

disconnecting point of the electric circuit, etc.) that there is

no operating voltage on the part to be tested and to con-

clude that the voltage indicated by the voltage detector is

an interference voltage.

•Voltage detectors with load connection:

A voltage detector declaring two values of internal im-

pedance has passed a performance test of managing

interference voltages and is (within technical limits) able

to distinguish operating voltage from interference voltage

and has a means to directly or indirectly indicate which

type of voltage is present.

•Switchtothevoltagemode:Pressthefunctionbuttonbriey

and repeatedly until „– – –

V

“ is shown on the display.

The voltage mode is the one which the device is set to after

it is turned on. Thus you only have to switch to voltage mode, if

you have conducted other work before.

•Connect both test tips to the object under test.

•Optional: By pressing both the load connection buttons simulta-

neously, an internal load will be connected, i.e. the impedance

is lowered, so that inductively/capacitively induced interference

voltagesaresuppressedanddonotinuencetheresult.

•Result:

If a life endangering threshold voltage 50 V

AC

or approx.

120 V

DC

is exceeded, the LED for dangerous voltage lights

up and the device warns acoustically and vibrates.

•The voltage is indicated by the LEDs and on the display.

• The polarity is indicated in following manner:

12 V + – LEDs light up = alternating current

12 V + LED lights up = positive direct current

12 V – LED lights up, display shows „–“ = negative direct

current

• When the L2 test tip is connected with a positive (negative)

potential, the LED 12 + (–) lights up.

During the voltage test, the L or R LED may light up. This

is due to technical reasons and does not signify anything.

6.3 Low voltage test –

0.5 V

AC

… 1000 V

AC

/ 0.5 V

AC

… 1500 V

DC

with polarity indication

The voltage indication (steps) via LED must not be used as

measurement. It is only an indication of voltage range.

In low voltage mode it is possible to measure alternating and direct

voltages from 0.5 V.

Continuity mode is disabled in low voltage mode.

• Switch to the low voltage mode: Press the function button brief-

ly and repeatedly until the display shows “LO

V

”.

• Connect both test tips to the object under test.

• Result:

The results are indicated as described in chapter 6.2 „Voltage

test (TRMS) with polarity indication“.

6.4 Single-pole phase test

The single-pole phase test must not be used to determine the

absence of voltage.

Proper function of this test is not be fully achieved if the

grounding conditions aren’t good enough. Insulating proper-

ties can adversely affect the test.

•Connect the L2 test tip to the object under test.

• Result:

ThesinglepoletestLEDlightsupandthebuzzersoundsifa

voltageof≥100V

AC

exists in the object under test.

6.5 Rotary eld test

Measurement principle: The device detects the phase rising order

regarding the user as earth.

Correct results can be obtained only on properly grounded

three-phase 4-wire systems.

Proper function of this test is not be fully achieved if the

grounding conditions aren’t good enough. Insulating proper-

ties can adversely affect the test.

Conduct a counter test, to verify the result. To do so, switch

the test tips around; the expected result is swapped display of

the result.

•Connect both test tips to the object under the test.

•Results:

• Phase-to-phase voltage is indicated with true value on the

display and via the voltage indication LEDs.

•TheRLEDlightsupforrightrotaryeld.

•TheLLEDlightsupforleftrotaryeld.

6.6 RCD trip test

For voltage tests in systems with RCDs (residual-current device,

also ground fault circuit interrupter – GFCI), an RCD can be tripped

with a 10 m A or 30 mA nominal leakage current in a single phase

AC 230 V power system.

•Connect the two test tips L and PE.

•Push both RCD trip buttons simultaneously.

• Expected result: The RCD trips.

If the RCD doesn’t trip, the system must be checked.

6.7 Continuity test (Rx)

Conrmthattestcircuit/objectisvoltagefreewitha2-pole

voltage tester. See voltage tests.

•Turn the device on. See chapter 5.1 „Switching on“.

• Connect both test tips to the test object.

•Result:

•Forcontinuity(uptoapprox.500kΩ)thecontinuitytestLED

andthedeviceisbuzzing.

• If no continuity is detected, the device off after approx. 30 s.

6.8 Diode test

Make sure the object under test voltage free. See voltage

tests.

•Switchtodiodemode:Pressthefunctionbuttonbrieyand

repeatedly until a small diode icon and „– d –“ are shown on

the display.

•Connect both test probes to the diode under test.

•Result:

•ThecontinuityLEDlightsup,thebuzzersoundscontinuous-

ly and forward voltage is shown the display, if the L1 – test

tip is connected to the anode of diode and L2 + test tip to

the cathode.

• Continuity LED will be off if the L1 – test tip is connected to

the cathode of the diode and L2 + tip to the anode.

If a voltage of > 6 V or a single pole voltage is detected, the de-

vice switches automatically to the voltage measurement (see

chapter 6.2 „Voltage test (TRMS) with polarity indication“).

6.9 Resistance measurement
