Safety information
WARNING
Before using, carefully read these instructions. If the instrument is not used as intended by the manufacturer, the
protection already provided can be influenced.
WARNING
Sources of danger are, for ex ample, mechanical parts, which may 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 personal injury and endanger the function of objects (e.g. damage to
the instrument).
WARNING
Unauthorised modification and / or changes to the i nstrument are not permitted, for reasons of safety and approval
(CE). In order to ensure safe and reliable operation using the instrument, you must always comply with the safety
instructions, warnings and the information contained in the section "Intended use".
WARNING
Comply with the following specifications before using the instrument:
Do not operate the instrument anywhere near electric welding equipment, induction heaters or other electromag-
|
netic fields.
| After abrupt changes in temperature, in order to stabilise the IR sensor, the instrument must be allowed to adjust
to the new ambient temperature for approx . 30 minutes before using it.
| At lower temperatures of less than 5 °C, the readiness of the voltage tester can be impaired. Please provide suf-
ficient power supply by using suitable batteries which are also specified for the appointed temperature range!
Do not ex pose 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 specifications of the accident prevention regula-
tions for electrical systems and equipment as established by the employer's liability insurance association.
Comply with the five safety rules:
1 Disconnect
2 Ensure that the instrument cannot be switched back on again
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
ex isting interference voltage cannot clearly indicate "operating voltage not present".
| If the indication "Voltage present" does not appear, before starting work, it is strongly recommended to insert the
earthing device.
| If the indication "Voltage present" appears for a part that is considered to be separate from the system, it is
strongly recommended to take additional action (e.g.: Use a suitable voltage tester, visual che ck of the separat-
ing 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 that the voltage indicated by the voltage tester is an interference volt-
age.
