Product Specifications
Tester Z10 is a device for a wide variety of measurements of both DC and AC voltage in the low voltage range.
Before you begin using the tester, please read this manual and follow the safety instructions.

Safety Instructions:

• The voltage tester may only be used in accordance with
standards DIN VDE 0105 section 100 and EN 50110-1.
Perform an operation test before using the device to
test voltage.
• The tester may only be used in voltage range of
12 V – 400 V AC/DC.
• The indication for exceeding the upper limit for ELV value
serves only as a warning.
• When measuring, hold the tester by the insulated parts, i.e.
the body and the grip of the tester tip, except when using
the tester with the tester tip grip inserted in the clamp.
• Voltage is tested exclusively using the metal tester tips.
• The volume level of the audio signalisation is set for
standard conditions only.
• The LED indication signalises 85 % of the value of indi-
cated voltage.
• The operating temperature of the tester is between
-15 °C to +60 °C.
• The operating humidity of the environment for using the
tester is between 20–98 %.
• The tester meets the enclosure requirements of IEC 605 29,
DIN 400 50 IP 64.
• The tester is tested in the production plant and sealed
against unauthorised intervention.
• Store the tester in a dry environment protected against
rain and weather conditions.
Attention: The tester can be at full load for an unlimited amount of
time. Upon disconnection, the tester tips retain no residual charge!
Operating Instructions:
Voltage tester Z10 is made of a material with high rigidity and
toughness, resistance to mineral oils, propellants, chlorinated
carbohydrates, common solvents and alkalis. It is resistant to
water and stable when exposed to mild acids. Tester Z10 uses an
optoelectronic version of signalisation based on a voltage divider.
Displaying is done via audio signalisation and HV discharge-based
glow lamp – indication and sequence of phases with LEDs – indica-
tion of AC or DC voltage levels in range of 12 V – 400 V. The tester
consists of a body, tester tip and connecting lead protected against
pulling out or twisting off. Voltage measurement is performed
exclusively using the metal tester tips by gripping the tester body
with one hand and the tester tip grip with the other. Measurement
can also be done with the mobile tester tip inserted into the clamp
using spacing appropriate for the socket.
Operating Modes
Operation Test
The tester may be used in voltage range of 12 V – 400 V AC/DC.
To perform the test, you need a source of ELV (extra low voltage
of up to 50 V) and LV (low voltage between 50 to 1,000 V) with
known parameters. If the optoelectronic or audio-signalisation
does not work, the tester may not be used any further.
Voltage Testing, Determining Polarity
1. Grip the tester body with one hand and the grip of the
mobile tester tip with the other, or insert the tester tip into
the clamp on the tester body (use spacing appropriate
for the socket).
2. Place the metal tester tips onto the points with electric po-
tential. When measuring ELV of up to 24 V, the plus (+) (on
the tester body tip) and minus (-) (on the mobile tester tip)
LEDs will light up, with their colour indicating the polarity
on the tips. For higher, LV voltage, the size of the impressed
voltage is indicated by LEDs lighting up up to the level corre-
sponding to the impressed voltage value. Audio signalisation
will sound at the same time. Its intensity is stable and is not
dependent on the impressed voltage value.
Phase Testing
The tester cannot be used in this mode on insulated pads,
structures and flooring materials or in grids with insulated
earth connection. Its use is possible only in favourable con-
ditions in relation to the earth connection.
Procedure:
1. Grip the body of the tester with the palm or the fingers
of the hand touching the metal electrode at the bottom
of the tester body.
2. Place the metal tester tip located on the body or the tester
tip located on the grip (does not matter which) onto the
measured point or conductor with AC HV (high voltage
of 1,000 V to 52 kV). The glow lamp glowing in orange
indicates phase point or conductor. Measurement can
also be done with the tester tip inserted into the clamp
with appropriate spacing.
Determining Phase Sequence
1. Grip the body of the tester with the palm or the fingers
of the hand touching the metal electrode at the bottom
of the tester body.
2. Place the metal tester tip on the tester body onto one
phase conductor while simultaneously placing the tester
tip on the grip onto a second phase conductor.
If a preceding phase is located on the tester body tip, the
glow lamp glows in orange and indicates the phase sequence.
Otherwise, the glow lamp is off.
Attention: Placing either the tester tip on the body or the tester tip on
the grip onto a measured point or conductor with AC voltage ensures
that the testing tips which are not used for measurement are not sup-
plied with voltage and do not retain any residual voltage or charge!
