Opsætning

Installation af batteri

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

1. Find batteridækslet på bagsiden af ​​enheden.
2. Brug en skruetrækker til at åbne låget.
3. Insert the six AA batteries, ensuring correct polarity (+/-).
4. Sæt batterirummets dæksel på igen og fastgør det.

Indledende inspektion

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.

Betjeningsvejledning

Tænd/sluk

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 Fungere)

1. Turn the rotary switch to the "A AC+DC" position.
2. Tryk på kæbeudløserhåndtaget for at åbne kæbenamp kæber.
3. Placer clamp jaws around a single conductor. Ensure the jaws are fully closed.
4. Læs den aktuelle værdi på LCD-skærmen.

Måling 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. Tilslut testproberne på tværs af det kredsløb eller den komponent, der skal måles.
4. Læs bindtage-værdi på LCD-skærmen.

Measuring Resistance (Ω)

1. Connect the test leads to the appropriate input jacks (COM and Ω).
2. Turn the rotary switch to the "Ω" position.
3. Sørg for, at kredsløbet er spændingsløst, før du måler modstanden.
4. Tilslut testproberne på tværs af den komponent, der skal måles.
5. Read the resistance value on the LCD.

Andre funktioner

• RÆKKEVIDDE: Manually select the measurement range if auto-ranging is not desired.
• HOLDE: Tryk for at fryse den aktuelle aflæsning på displayet. Tryk igen for at slippe.
• NUL: 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.

Opretholdelse

Rensning

Rengør måleren casing med annonceamp cloth and mild detergent. Do not use abrasives or solvents. Keep the display clean and dry.

Udskiftning af batteri

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.

Opbevaring

Opbevar klamp-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.

Fejlfinding

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

• Ingen skærm/strøm: 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.
• Upræcise læsninger: Verify that the correct measurement function is selected. Ensure test leads are properly connected and not damaged. For current measurements, ensure the clamp kæberne er helt lukket omkring en enkelt leder.
• 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.
