Configurar

Instalação da bateria

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

1. Localize a tampa do compartimento da bateria na parte traseira do dispositivo.
2. Use uma chave de fenda para abrir a tampa.
3. Insert the six AA batteries, ensuring correct polarity (+/-).
4. Recoloque a tampa do compartimento da bateria e fixe-a.

Inspeção Inicial

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.

Instruções de operação

Ligar/desligar

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 Função)

1. Turn the rotary switch to the "A AC+DC" position.
2. Press the jaw release lever to open the clamp mandíbulas.
3. Posicione o clamp jaws around a single conductor. Ensure the jaws are fully closed.
4. Leia o valor atual no LCD.

Vol de mediçãotage (CA/CC)

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. Conecte as pontas de prova ao circuito ou componente a ser medido.
4. Leia o vol.tage valor no LCD.

Medição de resistência (Ω)

1. Connect the test leads to the appropriate input jacks (COM and Ω).
2. Gire a chave rotativa para a posição "Ω".
3. Certifique-se de que o circuito esteja desenergizado antes de medir a resistência.
4. Conecte as pontas de prova ao componente que deseja medir.
5. Leia o valor da resistência no visor LCD.

Outras funções

• ALCANCE: Manually select the measurement range if auto-ranging is not desired.
• ESPERA: Pressione para congelar a leitura atual no visor. Pressione novamente para liberar.
• ZERO: Used to zero out DC current readings or resistance readings for lead compensation.
• Hz: Measures frequency.
• INVOCAÇÃO: Measures the peak current during motor startup.
• MIN MAX: Toggles through minimum, maximum, and average readings captured during a measurement session.
• FILTRO: Activates a low-pass filter to reduce electrical noise for stable readings.

Manutenção

Limpeza

Limpe o medidor casing com anúncioamp cloth and mild detergent. Do not use abrasives or solvents. Keep the display clean and dry.

Substituição da bateria

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.

Armazenar

Armazene o 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.

Solução de problemas

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

• Sem tela/energia: 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.
• Leituras imprecisas: Verify that the correct measurement function is selected. Ensure test leads are properly connected and not damaged. For current measurements, ensure the clamp jaws are fully closed around a single conductor.
• 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.
