Asennus

Akun asennus

The Fluke 355 requires six 1.5V AA batteries for operation. These are typically included with your purchase.

1. Paikanna laitteen takaosassa oleva paristolokeron kansi.
2. Avaa kansi ruuvimeisselillä.
3. Insert the six AA batteries, ensuring correct polarity (+/-).
4. Aseta paristolokeron kansi takaisin ja kiinnitä se.

Alkutarkastus

Before first use, inspect the clamp-meter, test leads, and accessories for any signs of damage. Do not use the device if any damage is observed.

Käyttöohjeet

Virran kytkeminen päälle/pois

Turn the rotary switch to any measurement function to power on the device. Turn the rotary switch to "OFF" to power off. The device will automatically power off after 20 minutes of inactivity to conserve battery life.

AC/DC-virran mittaaminen (Clamp Toiminto)

1. Turn the rotary switch to the "A AC+DC" position.
2. Avaa leukojen vapautusvipua painamalla.amp leuat.
3. Aseta clamp jaws around a single conductor. Ensure the jaws are fully closed.
4. Lue nykyinen arvo LCD-näytöltä.

Measuring Voltage (AC/DC)

1. Connect the test leads to the appropriate input jacks (COM and V).
2. Turn the rotary switch to the "V AC+DC" position.
3. Kytke mittausjohdot mitattavaan piiriin tai komponenttiin.
4. Lue voltage-arvo LCD-näytössä.

Measuring Resistance (Ω)

1. Connect the test leads to the appropriate input jacks (COM and Ω).
2. Käännä kiertokytkin "Ω"-asentoon.
3. Varmista, että virtapiiri on jännitteetön ennen resistanssin mittaamista.
4. Kytke mittausjohdot mitattavan komponentin päälle.
5. Lue vastusarvo LCD-näytöltä.

Muut toiminnot

• ALUE: Manually select the measurement range if auto-ranging is not desired.
• PITÄÄ: Paina pysäyttääksesi nykyisen lukeman näytölle. Paina uudelleen vapauttaaksesi toiminnon.
• NOLLA: Used to zero out DC current readings or resistance readings for lead compensation.
• Hz: Measures frequency.
• INRUSH: Measures the peak current during motor startup.
• MIN MAKSIMI: Toggles through minimum, maximum, and average readings captured during a measurement session.
• SUODATTAA: Activates a low-pass filter to reduce electrical noise for stable readings.

Huolto

Puhdistus

Puhdista mittari casing mainoksellaamp liinalla ja miedolla pesuaineella. Älä käytä hankaavia aineita tai liuottimia. Pidä näyttö puhtaana ja kuivana.

Akun vaihto

When the low-battery indicator appears on the display, replace all six AA batteries promptly to ensure accurate measurements. Follow the battery installation steps outlined in the Setup section.

Varastointi

Säilytä clamp-meter in its soft carrying case in a dry, dust-free environment when not in use. Remove batteries if storing for extended periods to prevent leakage.

Vianetsintä

If the Fluke 355 Clamp-Meter is not functioning as expected, consider the following:

• Ei näyttöä/virtaa: Check if the batteries are correctly installed and have sufficient charge. Replace batteries if necessary. Ensure the rotary switch is not in the "OFF" position.
• Epätarkkoja lukemia: Verify that the correct measurement function is selected. Ensure test leads are properly connected and not damaged. For current measurements, ensure the clamp leuat ovat täysin kiinni yhden johtimen ympärillä.
• Continuity Buzzer Not Working: Ensure the device is in the continuity measurement mode and the circuit is de-energized.

For persistent issues, refer to the official Fluke support resources or contact customer service.
