SAFETY AND WARNINGS
Do not exceed the maximum allowable input range of any function. Insulated
personnel body protective equipment up to 1000V. The unauthorized persons are
not allowed to disassemble the voltage detector.
In order to avoid electrical shock, the valid safety and VDE regulations regarding
excessive contact voltages must receive utmost attention, when working with volt-
ages exceeding 120V (60V) DC or 50V (25V) rms AC. The values in brackets are
valid for limited ranges (as for example medicine and agriculture).
Prior to measurement ensure that the test leads and the test instrument are in
perfect condition. The safety can no longer be insured if the instrument shows ob-
vious demage, does not carry out the desired measurents, has been stored for too
long under unfavorable conditions or has been subjected to mechanical stress
during transport. All relevant statutory regulations must be adhered to when using
this instrument.
When using the instrument, only the handles of the probes may be touched. Do
not touch the probe tips.
This instrument may only be used within the ranges specified and within low volt-
age systems up to 1000V.
Prior to usage ensure perfect instrument function. (e.g. on known voltage source).
The device is not te be used if the battery box is open and have to be kept dry
and clean. Do not use this instrument in damp conditions. Perfect display is oly
guaranteed within a temperaturerange of -10°C up to +55°C, at relative humidity
question <85%.
The voltage rester may no longer be used if one of several functions fail or if no
fucntionality is indicated. If the operator’s safety cannot be guaranteed, the instru-
ment must be removed from service and protected against use.
Please read the complete safety instructions in the booklet delivered with this
device.
SAFETY ADVICES
Depending on the internal impedance of the voltage detector there will be a
different capability of indicating the presence or absence of operating voltage in
case of the presence of interference voltage.
A voltage detector of relatively low impendance, compared to the reference value
of 100kΩ, will not indicate all interference voltages having an original voltage
value above the ELV level. When in contact with the parts to be tested, the voltage
detector may discharge temporarily the interference voltage to a level below the
ELV, but it will be back to the original value when the voltage detector is removed.
When the indication “voltage presenten” does not appeat, it is highly recom-
mended installing earthing equipment before work.
A votage detector of relatively high internal impedance, compared to the refer-
ence value of 100kΩ, may not permit to clearly indicate the absence of operating
voltage in case of presence of interfrence voltage.
When the indication “voltage present” appears on a part that expected to be
disconnected of the installation, it is highly recommended confirming by another
(e.g. use of an adequate voltage detector, visual check of the disconnecting point
of the electric circuit, etc.) that there is no operating voltage on the part to be
tested and to conclude that the voltage indicated by the voltage detector is an
interference voltage
