Safety information
WARNING
Read this manual carefully before using the instrument. Failure to use the instrument as intended by the
manufacturer can affect the protection which it provides.
WARNING
Sources of danger include for example, mechanical parts with the potential to cause serious personal injury.
Objects are also at risk (e.g. damage to the instrument).
WARNING
An electric shock can result in death or serious human injury and endanger the function of objects (e.g. damage to
the instrument).
WARNING
Unauthorised modification and / or changes to the instrument are not permitted, for reasons of safety and approval
(CE). In order to ensure safe and reliable operation of the instrument, you must always comply with the safety
information, warnings and the information contained in the section “Intended use”.
WARNING
Comply with the following specifications before using the instrument:
| The instrument may only be used in low voltage ranges up to max. 690 V.
| Avoid operating the instrument near to electric welding equipment, induction heaters or other electromagnetic fields.
| To stabilise the instrument after abrupt changes in temperature, the instrument must be allowed to adjust to the
new ambient temperature for approx. 30 minutes before using it.
| Temperatures below 5 °C can impair the readiness of the voltage tester. Please provide sufficient power supply
by using suitable batteries which are also specified for the appointed temperature range!
| Do not expose the instrument to high temperatures for a long period of time.
|
Avoid dusty and humid environments.
|
The voltage tester and accessories are not toys, and must be kept out of the reach of children!
|
When working in commercial facilities, comply at all times with the specifications of the accident prevention
regulations for electrical systems and equipment as established by the employer's liability insurance association.
Comply with the five safety rules:
1
Disconnect
2 Secure the instrument against reactivation
3 Ensure isolation from the power supply (check that there is no voltage on both poles)
4 Earth and short-circuit
5 Cover adjacent live parts
WARNING
| In comparison to the reference value of 100 k

, a voltage tester with relatively low impedance does not indicate
all interference voltages with an original value above the ELV. On contact with the parts of the system to be
tested, due to discharge, the voltage tester can temporarily diminish the interference voltages up to a level less
than the ELV; however, after removing the voltage tester, the interference voltage returns to its original value.
| In comparison to the reference value of 100 k

, a voltage tester with relatively high internal impedance at the
existing interference voltage cannot clearly indicate "operating voltage not present".
|
If the indication “Voltage present” does not appear, before starting work, we strongly recommend that you insert
the earthing device.
|
If the indication “Voltage present” appears for a part that is considered to be separate from the system, we
strongly recommend that you take additional action (e.g.: use a suitable voltage tester, visual check of the
separating point in the electrical circuit etc.) to verify and determine the condition of the “Operating voltage not
present” of the part of the system to be tested and determine that the voltage indicated by the voltage tester is
an interference voltage.
