VC64 TWO-PIN VOLTAGE TESTER
ITEM NO. 1313886
INTENDED USE
The two-pole voltage tester can be used to measure and display DC and AC voltages in an electrical
low-voltage circuit. The product also has an acoustic and visual circuit indicator as well as a resistance
measurement and an RCD test function. Power is supplied by two batteries of type
AAA/Micro included in the delivery.
The voltage tester complies with the standard for two-pole voltage testers of 12 - 690 V, CAT III 1000 V,
CAT IV 600 V according to EN 61243-3:2014/EN 60529 as well as protection class IP64 (dust and spray
water). The product is suitable for use in dry or damp conditions. Use during rain or other precipitation is
not permitted. The voltage tester is designed for use by electrically skilled persons using personal protec-
tive equipment.
The measuring instrument must not be operated when the battery compartment is open.
Measuring under adverse ambient conditions such as dust and flammable gases, vapours or solvents is
not permitted.
Always observe the safety instructions and all other information included in these operating instructions.
This product complies with the applicable national and European requirements. All names of companies

SAFETY INSTRUCTIONS
The warranty will expire in case of any damage caused by the failure to follow these
operating instructions! We assume no liability for any resulting consequential damage!
We assume no liability for any damage to property or personal injuries caused by
improper use or non-compliance with the safety instructions! In such cases, the warranty
will be null and void.
• T he unauthorised conversion and/or modification of the product is not permitted for safety and
approval reasons. Do not disassemble the product.
• This product is not a toy. Therefore, be especially careful when children are around.
Use the product where it is out of the reach of children.
• Never use the product immediately after it has been taken from a cold room to a warm one.
The condensation that forms can ruin the product under certain circumstances.
• Avoid the following adverse conditions at the location of installation and during transport:
- Extreme cold or heat, direct sunlight
- Dust or flammable gases, fumes or solvents
- Strong impacts, blows
• Do not leave packaging material carelessly lying around, since it could become a dangerous
plaything for children.
• Handle the product with care, it can be damaged by impacts, blows, or accidental falls, even
from a low height.
• Never touch the measuring tips or a measuring point during the measuring process. There is
a risk of electric shock.
• Never touch areas outside of the marked handling area during a measurement.
• D o not use in the immediate proximity of strong magnetic or electromagnetic fields or trans-
mission aerials. These can affect the measurement.
• Prior to and after each measurement, check your instrument and the measuring leads for
damages. Never take any measurements if the protecting insulation is defective or the
measuring instrument is damaged otherwise.
• Be especially careful when dealing with voltages higher than 50 V/AC or 75 V/DC. Even at
such voltages you can get a life-threatening electric shock if you come into contact with live
electric wires.
• The measuring instrument is suitable for use in dry or damp conditions. Avoid use in a damp
or wet environment.
• Always ensure that the probe tips are perfectly clean. Dirty or even corroded test clips can
lead to an incorrect measurement.
• The test probes must only be touched at the handles provided for this purpose. Otherwise,
there is danger of an electric shock.
VERSION 09/17
• Never exceed the highest permissible voltage values. If the stated values are exceeded, the
product becomes damaged and poses a hazard that can be fatal. (See chapter "Technical
data").
• T he recovery time as specified in "Technical data" must always be adhered to. Otherwise, the
product could be damaged.
• T he voltage values specified are nominal voltages.
• If the neutral wire (N) or the earth wire (PE) is interrupted, no reading is shown.
• The measuring instrument must only be used within the permissible ambient conditions (see
chapter "Technical data").
• Always attach the measuring tip cover if you are no longer using the device.
• Store the measuring instrument in a dry place, protected against dust, if you are no longer
using it.
• When using the voltage tester in the measurement category CAT III and CAT IV, it is recom-
mended to attach the plastic protective covers to the test probes to decrease the length of the
free contact tips. This reduces the risk of a possible short circuit during testing.
• Depending on the internal impedance of the voltage tester, there are different ways of
displaying "operating voltage present" or "operating voltage not present" in the presence of
interference voltage.
• A voltage tester with relatively low internal impedance does not display all interference
voltages with an initial value above ELV, compared to the reference value of 100 kΩ. Upon
contact with the parts to be tested, the voltage tester may temporarily reduce the interference
voltage by discharging to a level below ELV; however, after removing the voltage detector, the
interference voltage will assume its original value again.
• W hen the notification "voltage present" does not appear, it is strongly recommended that you
insert the earthing device before starting work.
• A voltage tester with relatively high internal impedance will not clearly display "operating
voltage present" in the event of existing interference voltage, compared to the reference value
of 100 kΩ.
• When "voltage present" appears on a part which is considered disconnected from the system,
it is strongly recommended to check the state "operating voltage not present" with additional
measures (e.g., using a suitable voltage tester, visual inspection of the disconnection point in
the electrical network, etc.) to make sure the voltage indicated by the voltage tester is not a
fault.
• A voltage tester indicating two values of the internal impedance has passed the design test
for handling interference voltages and is able to differentiate (within technical limits) the
operating voltage from the interference voltage and directly or indirectly display the existing
voltage type.
CAT I Measurement Category I is applicable to measuring circuits of electrical and electronic equip-
ment that is not directly supplied with mains voltage (battery-operated devices, etc.)
CAT II
Measurement Category II is applicable to measuring circuits of electrical and electronic equip-
ment that is directly supplied with the mains voltage via a power plug. This category also
covers all smaller categories (e.g. CAT I for measuring signal and control voltages).
CAT III
Measurement Category III is applicable to measuring circuits of installations in buildings (e.g.
electric sockets or sub-distributions). This category also covers all smaller categories (e.g.
CAT II for measuring electronic devices).
CATIV Measurement Category IV is applicable to measuring at the origin of the low-voltage installa-
tion (e.g. main distribution, electricity provider's transfer points to homes, etc.) and outdoors.
This category also contains all lower categories.
GENERAL BATTERY INSTRUCTIONS
• Batteries should be kept out of the reach of children.
• Do not leave batteries lying around in the open; there is a risk of them being swallowed by children or
pets. If they are swallowed, consult a doctor immediately.
• Leaking or damaged batteries can lead to caustic burning of the skin. Therefore, use suitable protective
gloves.
• B atteries must not be short-circuited, opened or thrown into fire. There is a risk of explosion.
• Make sure that the polarity is correct when inserting the batteries (pay attention to plus/+ and minus/–).
