Insulation & Continuity Testers
MEGGER
Safety Warnings and Precautions must be read
and understood before the instrument is used. They
must be observed during use.
The circuit under test must be de-energized and
isolated before connections are made except for
voltage measurement (BM400/2, BM401/2 and
BM403/2 only).
Circuit connections must not be touched during a
test.
After insulation tests, capacitive circuits must be
allowed to discharge before disconnecting the test
leads.
The default voltmeter and automatic discharge are
additional safety features and should not be
regarded as a substitute for normal safe working
practice.
Test leads and crocodile clips, must be in good
order, clean, with no broken or cracked insulation.
Replacement fuses must be of the correct type and
rating. See 'Specification'.
U.K. Safety Authorities recommend the use of fused
test leads when measuring voltage on high energy
systems.

CONTINUITY TESTING(Ω) Continuity tests are activated when the probes make contact. The test operates without the need to press the T E S T button.This range is not...

  • Página 4: Battery Check

    Zeroing of Test Lead Resistance The resistance of the test leads can be nulled on the Continuity ranges (up to 9,99 Ω). Select either Continuity range. Short the test leads across a known good conductor. When the reading has stabilized, press the TEST button. A short bleep will sound and will appear.

    Guide de l’utilisateur CONSIGNES DE SECURITE Désexciter et isoler le circuit avant d’effectuer des connexions, pour procéder à des essais, à l’exception des mesures de tensions. (BM400/2, BM401/2 et BM403/2 seulement). Ne pas toucher au circuit pendant un essai d’isolation. Après des essais d’isolation, attendre que les circuits capacitifs se soient déchargés, avant de débrancher les conducteurs d’essai.

  • Página 10: Essais De Continuité

    FONCTIONNEMENT Nous vous signalons que les essais d’isolation ne fonctionnent que tant que la pression sur le bouton d’essai se maintient. L’étiquette grise indique l’emplacement sur lequel il faut appuyer pour obtenir cette pression sur le bouton d’essai. Voir les Avertissement de Sécurité avant d’utiliser l’instrument.

  • Página 11: Sicherheitshinweise

    Betriebsanleitung SICHERHEITSHINWEISE B e v o r die Meßanschlüsse hergestellt werden, ist die Schaltung abzuschalten und zu isolieren. Dies gilt nicht für Spannungsmessungen. Die Schaltung darf nicht berührt werden, wenn Isolationsmessungen vorgenommen werden. Nach Abschluß der Isolationsmessungen sind kapazitive Kreise zu entladen, b e v o r die Meßkabel abgeklemmt werden.

    Guía del Usuario ADVERTENCIAS DE SEGURIDAD Se debe desactivar/desconectar el circuito a n t e s de hacer las conexiones para cualquier tipo de prueba, excepto para medir el voltaje. No tocar ninguna parte del circuito durante la prueba. Después de las pruebas de aislamiento, se debe dejar que los circuitos capacitativos se descarguen a n t e s de desconectar los conductores de prueba.

  • Página 14: Funcionamiento

    FUNCIONAMIENTO Nótese que la pruebas de aislameinto solamente funcionan cuando se pulsa el botón de prueba. Consultar los avisos de seguridad antes de usar el instrumento Prueba de aislamiento Poner el selector en la prueba de voltaje que se desea. Conectar los conductores, primero al instrumento, luego al elemento aislado que se desea probar.
