Safety notes
WARNING
An additional source of danger is posed my mechani-
cal parts which can cause severe personal injury.
Objects can also be damaged (e.g., the instrument it-
self can be damaged).
WARNING
An electric shock can result in death or severe injury.
It can also lead to property damage and damage to
this instrument.
WARNING
Never point the laser beam directly or indirectly (on re-
flective surfaces) towards the eyes. Laser radiation
can cause irreparable damage to the eyes. You must
first deactivate the laser beam when measuring close
to people.

General safety notes
WARNING
Unauthorized changes or modifications of the instru-
ment are forbidden – such changes put the approval
(CE) and safety of the instrument at risk. In order to
operate the instrument safely, you must always ob-
serve the safety instructions, warnings and the infor-
mation in the "Proper and Intended Use" Chapter.
WARNING
Please observe the following information before using
the instrument:
| Do not operate the instrument in the proximity of
electrical welders, induction heaters and other elec-
tromagnetic fields.
| After an abrupt temperature fluctuation, the instru-
ment should be allowed to adjust to the new tem-
perature for about 30 minutes before using it. This
helps to stabilize the IR sensor.
| Do not expose the instrument to high temperatures
for a long period of time.
| Avoid dusty and humid surroundings.
| Measurement instruments and their accessories are
not toys. Children should never be allowed access
to them!
| In industrial institutions, you must follow the acci-
dent prevention regulations for electrical facilities
and equipment, as established by your employer's
liability insurance organization.

ENGLISH
Please observe the following five safety rules:
1 Disconnect.
2 Ensure that the instrument cannot be turned back
on again.
3 Ensure isolation from the main supply voltage
(check that there is no voltage on both poles).
4 Earth and short-circuit.
5 Cover neighbouring parts that are under live elec-
trical load.
Proper and intended use
This instrument is intended for use in applications described in
the operation manual only. Any other usage is considered im-
proper and non-approved us-age and can result in accidents or
the destruction of the instrument. Any misuse will result in the
expiry of all guarantee and warranty claims on the part of the
operator against the manufacturer.

in such cases. An exclamation mark in a triangle indi-
cates safety notices in the operating instructions. Read
the instructions completely before beginning the initial
commissioning. This instrument is CE approved and
thus fulfils the required guidelines.

Disposal
For Testboy customers: Purchasing our product gives you the
opportunity to return the instrument to collection points for
waste electrical equipment at the end of its lifespan.
The EU Directive 2002/96/EC (WEEE) regulates the
return and recycling of waste electrical and electron-
ics equipment. As of 13/08/2005, manufacturers of
electrical and electronics equipment are obliged to
take back and recycle any electrical devices sold af-
ter this date for no charge. After that date, electrical
de-vices must not be disposed of through the "nor-
mal" waste disposal channels. Electrical devices
must be disposed of and recycled separately. All de-
vices that fall under this directive must feature this
logo.
Disposing of used batteries
As an end user, you are legally obliged (by the rele-
vant laws concerning battery disposal) to return
all used batteries. Disposal with normal house-
hold waste is prohibited!
Contaminant-laden batteries are labelled with the
adjacent symbol which indicates the prohibition of
disposal with normal household waste.
The abbreviations used for heavy metals are:
Cd = Cadmium, Hg = mercury, Pb = lead.
You can return your used batteries for no charge to
collection points in your community or everywhere
where batteries are sold!

Operation
Thank you for choosing the Testboy®20 Plus. The Testboy®20
Plus represents the latest advancement in the popular Testboy®
2 series. It features six professional functions for working with
electrical cables and wires:
| Low-ohm, optical continuity testing
| High-ohm, acoustic continuity testing
| High-power LED flashlight
| Non-contact voltage testing
| Single-pole phase searching
| Protection from external voltages of up to 300 V
Optical continuity testing
Insert the test leads (as shown
in Figure 1a).
The large LED display will illu-
minate between 0 to 20 Ω. The
intensity of the light decreases
proportionally after 10 Ω.
If an unexpected voltage is ap-
plied to the object being meas-
ured, the light will illuminate.
If a phase is active on one of
the wires being tested, the red
V~ LED will illuminate!
Figure 1a

Operation
22 Testboy® 20 Plus
Acoustic continuity testing
Insert the test leads (as shown
in Figure 1b).
An acoustic signal can be
heard between 0 – 250 Ω. The
green LED illuminates at
the same time.
If an unexpected voltage is ap-
plied to the object being meas-
ured, the light will illuminate
and the buzzer will issue a
warning tone!
If a phase is active on one of
the wires being tested, the red
V~ LED will illuminate!
The Testboy®20 Plus is pro-
tected against external volt-
ages of up to 300 V~ (for max.
30 seconds)!
You can carry out a continuity
test while the flashlight is on!

ENGLISH
Non-contact voltage test
No test leads need to be attached (as
show in Figure 2)!
The circuitry located in the back of the
Testboy®20 Plus can detect live-
voltage wires with voltages greater
than >110 V AC.
A flowing current is not required! The
metal clip acts here as an extended
sensor.
It is not dangerous to touch this metal
clip!
Figure 2
Single-pole phase searching
Plug a test lead in the COM port (as
shown in Figure 3).
Then touch the probe tip to the wire.
Be sure not to touch the clip attached
to the back side (move to up position).
If a phase is active, the rote V~ LED
will illuminate!
The sensitivity of the electronics in-
creases if the metal clip is contacted
during the measurement. This means
that AC voltage fields can be detected
even at distances of several millime-
tres!
It is not dangerous to touch this metal
clip!

Changing the batteries
Use a screwdriver to leverage the up-
per housing section upwards and to-
wards the front, between the protrud-
ing knobs and the middle socket (refer
to Figure 4). To remove the lid, un-
hook downwards. Make sure you in-
sert the new batteries with the polarity
properly aligned!
Do not dispose of batteries in
normal household rubbish!
Use an authorised local col-
lection point!
Figure 4
WARNING! DANGER OF DEATH!
All test leads should be removed before opening up
the continuity tester!
Flashlight
Slide the switch on the side of the tester downwards. The high-
performance LED can illuminate for up to 80 hours! The lifespan
of the LED is over 100,000 hours.
