2. Saugos informacija

To ensure safe operation and avoid damage to the meter, please read this manual carefully before use. Adhere to all safety warnings and precautions.

• Always ensure the test leads are correctly connected to the appropriate input terminals for the measurement being performed.
• Do not exceed the maximum input limits for any function. The OW18B is rated for 1000V CAT III and 600V CAT IV.
• Būkite ypač atsargūs dirbdami su ttagesant didesnei nei 30 V AC RMS, 42 V pikinei vertei arba 60 V DC įtampai. Šie įtampų lygiaitagtai kelia šoko pavojų.
• Before measuring current, ensure the circuit is de-energized and the meter is connected in series with the load.
• Kai pasirodys išsikrovusio akumuliatoriaus indikatorius, nedelsdami pakeiskite bateriją, kad užtikrintumėte tikslius rodmenis.
• Nenaudokite skaitiklio, jei jis atrodo pažeistas arba jei korpusas yra atidarytas.
• Use only specified replacement parts when servicing the meter.
• Matavimo metu laikykite pirštus už zondo užtvarų.

5.2 tomastagMatavimas (AC/DC)

1. Connect the black lead to the COM jack and the red lead to the VΩHz jack.
2. Rotate the function switch to the V~ (AC Voltage) arba V- (nuolatinė tūriotage) padėtis.
3. Prilieskite bandymo zondus prie grandinės taškų, kuriuose yra įtampatage turi būti išmatuotas.
4. Perskaitykite ttage value on the display. The meter supports True RMS for AC measurements.

5.3 Srovės matavimas (AC/DC)

Atsargiai: Niekada nejunkite skaitiklio lygiagrečiai su įtampos matuokliutage source when measuring current. This can damage the meter and pose a safety risk.
