5. Configuració

5.1 Instal·lació de la bateria

1. Assegureu-vos que el comptador estigui apagat.
2. Localitzeu la tapa del compartiment de la bateria a la part posterior del mesurador.
3. Feu servir un tornavís per afluixar el(s) cargol(s) que fixen la tapa de la bateria.
4. Traieu la tapa de la bateria.
5. Insert three AAA 1.5V batteries, observing the correct polarity (+ and -).
6. Torneu a col·locar la tapa de la bateria i estrenyeu el(s) cargol(s).

Figura 5.1: posterior view del clamp meter, indicating the battery compartment location.

5.2 Connexió dels cables de prova

Per al voltage, resistance, capacitance, frequency, duty cycle, diode, and continuity measurements:

• Insert the red test lead into the "INPUT" terminal.
• Insert the black test lead into the "COM" (common) terminal.

6. Instruccions de funcionament

6.1 Encès/Apagat

Rotate the function dial from the "OFF" position to any desired measurement function to turn the meter ON. To turn OFF, rotate the dial back to the "OFF" position.

6.2 Selecció de la funció

The large rotary dial allows selection of various measurement functions. Some positions on the dial may have multiple functions (e.g., AC voltage i DC voltage). Premeu el botó "SEL" button to cycle through these functions.

6.3 Mesura de corrent AC/DC (Clamp)

1. Rotate the function dial to the "A~" (corrent altern) o "A=" Posició (corrent continu).
2. Premeu el clamp gallet per obrir les mandíbules.
3. Enclose a single conductor (not a power cord with multiple wires) within the clamp mandíbules. Assegureu-vos que les mandíbules estiguin completament tancades.
4. Llegiu el valor actual a la pantalla LCD.
5. For DC current, observe the polarity indicated on the display.

6.4 AC/DC Voltage Mesura

1. Connect the red test lead to the "INPUT" terminal and the black test lead to the "COM" terminal.
2. Rotate the function dial to the "V~" (Volum AC)tage) o "V=" (DC Voltage) position. Use the "SEL" botó si cal.
3. Connecteu els cables de prova en paral·lel al circuit o component que s'està provant.
4. Llegeix el voltagValor a la pantalla LCD.

6.5 Resistance, Capacitance, Frequency, Duty Cycle, Diode, and Continuity

For these measurements, connect the test leads as described in Section 5.2. Rotate the function dial to the appropriate position and use the "SEL" button to select the specific function if multiple are available on one dial position.

• Resistència (Ω): Assegureu-vos que el circuit estigui desenergitzat abans de mesurar la resistència.
• Capacitat (F): Discharge capacitors before measurement.
• Freqüència (Hz) / Duty Cycle (%): Connecteu-vos a través de la font de senyal.
• Prova de díodes (→|): Connect the red lead to the anode and black lead to the cathode.
• Prova de continuïtat ()))): A built-in buzzer will sound if the resistance is below approximately 50Ω.

6.6 Funcions especials

• "HOLD" Button: Press to freeze the current reading on the display. Press again to release.
• "MAX/MIN" Button: Press to enter MAX/MIN recording mode. The meter will display the maximum or minimum value measured since entering the mode. Press again to cycle between MAX, MIN, and current reading. Hold to exit.
• "REL" (Relative) Button: Press to store the current reading as a reference value. Subsequent measurements will be displayed as the difference from this reference. Press again to exit.
• Backlight/Clamp Llum: The backlight and clamp light can be activated for improved visibility in low-light conditions. Refer to the specific button on the meter (often combined with another function or a dedicated light button).

7. Manteniment

7.1 Neteja

Netegeu el cas amb l'anunciamp cloth and mild detergent. Do not use abrasives or solvents. Keep the terminals free of dirt and moisture.
