2. Sikkerhedsoplysninger

Always observe basic safety precautions when using this multimeter to avoid personal injury or damage to the meter or equipment under test. Read the following safety information carefully before use.

• Overskrid ikke den maksimale volumentage rating specified for any function.
• Vær forsigtig, når du arbejder med voltagover 30V AC RMS, 42V peak eller 60V DC. Disse voluminertages udgør en stødfare.
• Frakobl altid testledningerne fra kredsløbet, før du skifter funktioner.
• Sørg for, at måleren er i den korrekte funktion og område til målingen.
• Undersøg testledningerne for beskadiget isolering eller blotlagt metal før brug. Udskift dem, hvis de er beskadigede.
• Brug ikke måleren, hvis den ser beskadiget ud, eller hvis huset er åbent.
• Remove the batteries if the meter is not used for a long period.

5. Opsætning

5.1 Batteriinstallation

The multimeter requires two 1.5V AAA batteries (not included) for operation. To install or replace batteries:

1. Sørg for, at multimeteret er slukket, og frakobl alle testledninger.
2. Find batteridækslet på bagsiden af ​​enheden.
3. Brug en skruetrækker til at åbne batterirummet.
4. Isæt to AAA-batterier, og overhold den korrekte polaritet (+/-) som angivet inde i batterirummet.
5. Sæt batterirummets dæksel på igen og fastgør det med skruen.

5.2 Tilslutning af testledninger

Korrekt tilslutning af testledninger er afgørende for nøjagtige og sikre målinger.

• Sæt den sorte testledning i 'COM' (Common) indgangsstikket.
• Insert the red test lead into the 'VΩHz' input jack for voltage, resistance, frequency, and diode measurements.
• For current measurements (mA/A), insert the red test lead into the 'A mA' input jack. For microampere measurements (uA), insert the red test lead into the 'uA' input jack.
