1. Safety instructions
- During the tests, touch the device at the insulated
test probes 9, and only and do not touch
the bare testing electrodes 8!
- Check the device for correct functioning immediately before and after using it (see section 3)! Do
not use the device, if one or more indications are
not working or if it does not seem to be ready for
operation!
- If it is assumed that safe operation is no longer
possible, the device must be switched off immediately.
- Absolutely prevent the device from getting wet
and avoid any water condensation at the device.
Moreover, the device must be protected against
contamination and damaging!
- The device must be used within the stated nominal voltage range and in electrical installations of
up to 500 V AC only!
- The device must be used only in electric circuits
of overvoltage category CAT III with max. 300 V
for phase-to-earth measurements. For measurements within measuring category III, the protruding conductive part of a testing electrode 8 of the
test probe must not be longer than 4 mm. Before
carrying out measurements within measuring category III, the enclosed attachable protective caps
marked with CAT III must be pushed onto the testing electrodes 8 for user protection purposes.
- Please observe that work on live parts and electrical components of all kinds is dangerous! Even
low voltages of 30 V AC and 60 V DC may be
dangerous to human life!
- Do not operate the device with the battery compartment being open.
- The device is designed for being used by qualified
electricians and under safe working conditions.
- Do not dismantle the device!
Attention!
The device is provided with a high-power LED torch.
Do not look directly or indirectly via reflecting surfaces
into the LED beam. An LED beam might cause irreparable damage to your eyes.

Warning! Potentially dangerous optical
radiation!
Do not look directly into the light beam!
Danger to your retina!
Attention! Magnets might affect the correct functioning of cardiac pacemakers
and implanted defibrillators. As a user of
such medical devices, keep a sufficient
distance to the magnet.

3. Functional test
- Check the device for correct functioning immediately before and after using it!
- Test the correct functioning of the LEDs
and 3 for indicating the external conductors L1,
L2 and L3 as well as the LEDs 4 and 5 of the
phase sequence indication with a familiar voltage
source, e.g. a 400 V CEE socket.
- Do not use the device, if not all functions are
working properly!
- Please replace the batteries as soon as the luminosity of the LED torch 6 decreases.
4. Phase sequence test
- Connect the connecting cables marked with L1,
L2 and L3 to the mains to be tested. For this purpose, use the test probes 9, and or the alligator clip .
- The external conductor voltages are indicated by
means of the red LEDs 1, 2 and 3.
- Depending on the connection, the red LED (4) for
"counter-clockwise phase sequence" or the green
LED 5 for "clockwise phase sequence" will be
activated.
- Interchanging the test probes on two external
conductors must result in a change of the phase
sequence.
- For each test, make sure that all three external
conductor voltages are present. Only then, the
indicated results can be analyzed!

Note:
Phase sequence tests can be carried out even with
the batteries being removed or exhausted.
5. LED torch
Warning!
Potentially dangerous optical radiation!
Do not look directly or indirectly via
reflecting surfaces into the LED beam!
Danger to your retina!
- The device is provided with a high-power LED
torch 6 with can be switched on and off by pressing the push-button 7.
6. Battery replacement
- Do not apply voltage to the device when the battery compartment is open!
- The battery compartment is located on the back of
the device.
- Slightly press down the catch by means of a
screwdriver and push off the battery compartment
cover in downward direction at the same time.
- Replace the exhausted batteries by three new
ones of type AA (LR06). Make sure that the new
batteries are inserted with correct polarity!
- Push the battery compartment cover back onto
the housing until the catch locks into place with
an audible click.
Note:
The battery compartment cover is provided with an
integrated magnet and a belt clip for attachment of the
device.
