G Safety Information

To ensure safe operation and service of the meter, follow these

instructions.

Failure to observe warnings can result in severe injury or death.

■ Avoid working alone so assistance can be rendered.

■ Do not use the clamp meter if the instrument looks damaged

■ Do not use the clamp meter if the tester is not operating properly or

if it is wet.

■ Use the clamp meter only as speciﬁed in the instruction card or the

protection provided by the clamp meter may be impaired.

■ Ensure hands are kept behind the barrier / hand guard when making

measurements.

■ Special precautions are necessary when operating in situations where

exposed live parts at dangerous voltages may be encountered.

Personal protective equipment (not supplied with the instrument)

should be used.

■ Use caution with voltages above 30 V AC RMS, or 60 V DC. These

voltages pose a shock hazard.

Auto Hold Enable / Disable

In the AUTOHOLD mode, if the measured value remains within ±10 counts

over 10 measuring cycles the instrument will beep 3 times; the measured

value will be held on the display and “AUTOHOLD” will be displayed.

Subsequently if the measured value changes by ±10 counts, the instrument

will beep; “AUTOHOLD” will disappear and the instrument will revert to

displaying the new readings until the next AUTOHOLD conditions are met.

Note: When the AUTOHOLD activates, the displayed reading will be held for 3

seconds if the clamp jaws are removed from the conductor/s. During this time

the HOLD key may be pressed to hold the reading indeﬁnitely.

Auto Backlight

The Auto backlight on the display activates automatically when the instrument

is used in very poor light locations

G Sicherheitsinformationen

Für eine sichere Bedienung und eine sichere Wartung des Messgeräts bitte

diese Anweisungen beachten.

Eine Nichtbeachtung der Warnhinweise kann zu schweren Verletzungen oder

zum Tod führen.

■ Niemals alleine arbeiten, sodass im Notfall Hilfe geleistet werden

kann.

■ Leckstromzange nicht benutzen, wenn das Gerät beschädigt aussieht

■ Leckstromzange nicht benutzen, wenn das Messgerät nicht

ordnungsgemäß funktioniert oder wenn es nass ist.

■ Leckstromzange nur für die in der Bedienungsanleitung

beschriebenen Arbeiten verwenden, sonst kann der Schutz durch die

Leckstromzange evtl. nicht gewährleistet sein.

■ Sicherstellen, dass die Hände während des Messvorgangs hinter der

Griffbegrenzung / dem Handschutz gehalten werden.

■ Besondere Vorsicht ist erforderlich bei Arbeiten in Bereichen, in

denen frei liegende, spannungsführende Bauteile mit gefährlichen

Spannungen vorhanden sein können. Es muss persönliche

Schutzausrüstung verwendet werden (wird nicht zusammen mit dem

Gerät geliefert).

■ Vorsichtig sein bei Spannungen über 30V AC EFF oder 60V DC. Bei

diesen Spannungen besteht die Gefahr eines Stromschlags.
