Nastavitev

Namestitev baterije

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

1. Poiščite pokrov predalčka za baterije na zadnji strani naprave.
2. Z izvijačem odprite pokrov.
3. Insert the six AA batteries, ensuring correct polarity (+/-).
4. Ponovno namestite pokrov prostora za baterije in ga pritrdite.

Začetni pregled

Pred prvo uporabo preglejte clamp-meter, test leads, and accessories for any signs of damage. Do not use the device if any damage is observed.

Navodila za uporabo

Vklop/izklop

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.

Measuring AC/DC Current (Clamp Funkcija)

1. Turn the rotary switch to the "A AC+DC" position.
2. Pritisnite ročico za sprostitev čeljusti, da odprete zaklepamp čeljusti.
3. Postavite clamp jaws around a single conductor. Ensure the jaws are fully closed.
4. Odčitajte trenutno vrednost na LCD-zaslonu.

Merjenje 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. Merilne sonde priključite na vezje ali komponento, ki jo želite izmeriti.
4. Preberite zvtage vrednost na LCD -prikazovalniku.

Measuring Resistance (Ω)

1. Connect the test leads to the appropriate input jacks (COM and Ω).
2. Obrnite vrtljivo stikalo v položaj "Ω".
3. Pred merjenjem upornosti se prepričajte, da je tokokrog izklopljen.
4. Merilne sonde priključite na komponento, ki jo želite izmeriti.
5. Odčitajte vrednost upora na LCD-prikazovalniku.

Druge funkcije

• OBMOČJE: Manually select the measurement range if auto-ranging is not desired.
• DRŽI: Pritisnite , da zamrznete trenutni odčitek na zaslonu. Ponovno pritisnite , da spustite gumb.
• NUČ: 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 MAX: Toggles through minimum, maximum, and average readings captured during a measurement session.
• FILTER: Activates a low-pass filter to reduce electrical noise for stable readings.

Vzdrževanje

Čiščenje

Očistite merilnik casing z oglasomamp cloth and mild detergent. Do not use abrasives or solvents. Keep the display clean and dry.

Zamenjava baterije

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.

Shranjevanje

Shranite 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.

Odpravljanje težav

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

• Brez zaslona/napajanja: 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.
• Netočni odčitki: Verify that the correct measurement function is selected. Ensure test leads are properly connected and not damaged. For current measurements, ensure the clamp čeljusti so popolnoma zaprte okoli enega samega prevodnika.
• 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.
