Safety information
WARNING
Read this manual carefully before using the instrument. Failure to use the instrument in accordance with the manufac-
turer’s specifications can affect the protection which it provides.
WARNING
Sources of danger include e.g. mechanical parts, which can cause serious injuries. Objects are also at risk (e.g. damage
to the instrument).
WARNING
An electric shock can result in death or serious injury and jeopardise the function of objects (e.g. damage to the instru-
ment).
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
Observe the following information before using the instrument:
| Avoid operating the instrument near to electric welding equipment, induction heaters or other electromagnetic fields.
| To stabilise the instrument after abrupt changes in temperature, it must be allowed to adjust to the new ambient tem-
perature for approx. 30 minutes before use.
| Temperatures below 5 °C can impair the readiness of the voltage tester. Please provide a sufficient power supply by
using suitable batteries as specified for the deployed 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 industrial facilities, comply at all times with the accident prevention regulations for electrical systems
and equipment as established by the employers’ liability insurance association.
Please observe the five safety rules:
1 Disconnect
2 Secure 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
| Compared with 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, dis-
charge can mean that the voltage tester temporarily diminishes the interference voltages to a level under the ELV.
Removing the voltage tester returns the interference voltage to its original value.
| Compared with the reference value of 100 k, a voltage tester with relatively high internal impedance will not clearly
indicate “Operating voltage not present” when an interference voltage exists.
| If the display “Voltage present” does not appear, we strongly recommend that you insert the earthing device before
starting the work.
| If the display “Voltage present” appears for a part that is considered to be separate from the system, we strongly rec-
ommend that you take additional action (e.g.: use a suitable voltage tester, visually check the separating point in the
electrical network, etc.), verify and determine the “Operating voltage not present” state of the part of the system to be
tested and determine that the voltage indicated by the voltage tester is an interference voltage.
