• The device tests the leads automatically one by one.

Errorsignal

• Disconnection – if one or more wires are diconnected, the LEDs with same

number do not light on the main unit and on the removable control unit

• Short circuit – If more wires are short-circuited, more LEDs light on the main

unit and on the removable control unit at the same time.

MaintenanCe

• Note that the device is not water-, dust- and shock- resistant.

• Do not use and do not store the device at high temperatures, in places with

way:

• Take the device out of the plastic holder and take o the battery holder cover.

• Take out the battery and replace it to a new one. Use alkaline batteries if

possible.

• Fix the battery holder cover and put the plastic holder back.

Fusereplacement

• Only use the prescribed types of fuses for replacing.

If the device does not operate properly, check the following

BiztOnsági Megjegyzés

A mérőműszer az EN61010-1 szabványoknak megfelel. Használat előtt gyelme-

sen olvassa el a használati utasítást.

• Ne mérjen nagyobb értéket a beállított méréshatárnál.

• Az elektromos áramütés elkerülése miatt ellenőrizze, hogy a műszerzsinórok

sérülés mentesek legyenek.

• Ügyeljen rá, hogy funkcióváltáskor a műszerzsinórok a megfelelő aljzatba

legyenek bedugva.

• Válassza ki a helyes funkciót és méréshatárt, kerülje el a hibás műveleteket.

• Ne használja a mérőműszert, ha az elemtartó fedele és a hátlapja nincs a

helyére rögzítve.

• Ellenállásmérés állásban ne mérjen feszültséget.

• Húzza ki a vezetékeket és kapcsolja ki a műszert, mielőtt kicseréli az elemet

vagy a biztosítékot.
