4 2 round LEDs (red) for indicating AC/DC/ polarity 5 Triangular LED (red) "Pol-L1" for phase and 6 Accessible electrode "Pol-L1-Sensor" for 7 Solar cell for charging the integrated lithium The PROFISAFE is a two-pole voltage tester in
accordance with EN/IEC 61243-3 (VDE 0682 part
401) with LED display. You can use the
PROFISAFE to measure DC and AC voltages
PROFISAFE400: 12 . 400 V
PROFISAFE690: 24 . 690 V.
Furthermore you can determine polarity, phase
and phase sequence and perform continuity tests
up to 500 k. The energy for the additional func-
tions (continuity/phase sequence/phase) is sup-
plied by an integrated storage lithium battery
which is charged by a high-performance solar cell,
even at a minimum light level. The intrument does
not require any batteries. The proprietary energy
source is not necessary for voltage testing. Thanks
to its high degree of protection (IP 65) the
PROFISAFE may even be used in rain.
You have chosen an instrument which provides
you with a high level of safety. The PROFISAFE
voltage tester has been approved by VDE test
authorities for application of VDE GS marking.
When used for its intended purpose, the safety of
the operator, as well as that of the instrument, is
In order to maintain flawless technical safety conditions,
and to assure safe use, it is imperative that you read
these operating instructions thoroughly and carefully
before placing your instrument into service, and that you
follow all instructions contained therein.
The voltages indicated on the PROFISAFE are
nominal values. The voltage tester may only
be used in systems working with the specified
nominal voltage range.
Faultless indication of display values is only guaranteed between –10 ° and +55 °C.
Hold the instrument by its handles only, to avoid covering the display and touching the test electrodes before and during tests.
Just before they are used, voltage testers need to be checked to ensure they function correctly. Carry out the function test and check the instrument at a familiar voltage source – e.g. a 230 V socket. If the display of one or several systems fails in the course of testing, the instrument may no longer be used.
The PROFISAFE must not be switched on for
more than 30 seconds.
For the determination of phase conductors and phase sequence by means of the acces-sible electrode, the perceptibility of the display may be impaired, e.g. when using protection means against direct contact, in unfavourable locations, for example on wooden ladders or insulating floor coverings, as well as in unfavourable lighting conditions and in an improperly grounded AC voltage system.
The voltage tester may only be dismantled by authorized personnel.
Voltage testers must be clean and dry.
The innovative concept of the PROFISAFE allows
for voltage measurements even with entirely
depleted storage batteries. Thanks to the solar cell
and the permanently integrated lithium storage
battery the PROFISAFE is always ready for conti-
nuity tests without the need for battery replace-
ment. Please proceed as follows to test the
correct functioning of the PROFISAFE:
To test the functions and the proprietary energy source, put the test electrodes together. The rect-angular green LED (continuity test) lights up per-manently. Subsequently, test the instrument at a familiar voltage source, e. g. a 230 V mains outlet.
If one of the LED does not light up, theinstrument may no longer be used.
If the green LCD, after putting the test electrodes together, flickers or does not light up, you have to recharge the storage battery (scontinuity tests. Voltage tests can still be con-ducted without the storage battery. Voltage testing is always active.

Switch-over to continuity test, continuity is indicated by green LED  The maximum allowable on-time for volt-age testing is 30 seconds.
Both lower 12 V/24 V LEDs () light up alterna-tively when an AC voltage within the nominal volt-age range is applied to both test electrodes. The LED chain located above lights up according to the voltage applied.
When a DC voltage within the nominal voltage range is applied to both test electrodes, one of the lower 12 V/24 V LEDs () and the LED chain located above light up according to the voltage applied. Polarity is determined as follows: The "+" 12 V/24 V electrode lights up when the test probe marked "+" is connected to the positive pole. The PROFISAFE is equipped with an accessible
electrode "Pol-L1-Sensor", and a triangular LED
for phase testing and phase sequence indication.
While working with the accessible elec-trode the perceptibility of the display may be impairedfety Pre-cautions).
Tests with the accessible electrode only function in properly grounded AC voltage systems with volt-ages as from approx. 165 V towards earth.
The phase conductor is identified by establishing con-tact between one of the two test probes and the con-ductor, and by simultaneously touching the accessible electrode "Pol-L1-Sensor" with your finger. If the triangle lights up, the conductor is energized.
To determine the phase sequence between two phases in a grounded 230/400 V 3-phase system by applying both test electrodes and touching the accessible electrode, proceed as follows:➭ Search for the phase conductors using one pole (see phase test).
Apply both test electrodes to two phase con-ductors (display value: approximately 400 V).
Touch the accessible electrode with your finger. If phase L1 is applied to the test probe marked + L1 and phase L2 to the other test probe, the trian-gle lights up if rotation is clockwise. If the triangle does not light up, the direction of rotation is counter-clockwise. If 230 V is displayed instead of 400 V, the neutral conductor may have been con-tacted with one of the test probes. Apply the test electrodes to the conductor to be
tested. The rectangular green LED lights up at a
resistance of 0 to about 500 k. The green rectan-
gle lights up if the test probe of the PROFISAFE
marked "+" is applied to the anode of a semicon-
ductor. Otherwise the semiconductor is connected
in the reverse direction.
The instrument is immediately ready for the next test. Voltage readings always take priority (see 9 LEDs for voltage, continuity, phase and phase sequence PROFISAFE400:

Extract from table on the meaning of IP codes Rubber insulated flexible cable H07RN-F, 1m If the green LED does not flash or light up when
putting together the test probes, you have to
recharge the battery. Place the instrument in a light
source (e.g. on a window sill) with the display field
facing upward. Due to the high-performance solar
cell, the PROFISAFE wil be fully functional within a
short period of time (approx. 15 minutes). Perform
the function test before putting the instrument
back into operation (see 3.1).
Please do not use halogen lamps for charging, otherwise the device might be damaged.
The voltage tester should be kept dry and clean. The plastic housing can be cleaned with a cloth dampened with isopropyl alcohol or soapy water.
