2. Informació de seguretat
Per garantir un funcionament segur, seguiu sempre les precaucions de seguretat següents:
- Read and understand all instructions before using the meter.
- Observe all safety warnings and instructions marked on the meter.
- This meter is rated for CAT III 600V. Do not exceed the maximum input values specified for each function.
- Do not use the meter if it appears damaged or if the flexible inductor is compromised.
- Desconnecteu sempre els cables de prova del circuit abans de canviar les funcions.
- Extremeu les precaucions quan treballeu amb circuits en tensió. Alt volumtagi pot provocar una descàrrega elèctrica.
- Mantingueu els dits darrere dels protectors per als dits dels cables de prova durant les mesures.
- Canvieu les piles immediatament quan aparegui l'indicador de bateria baixa per garantir lectures precises.

4. Configuració
4.1 Instal·lació de la bateria
The PM2019A/PM2019S is powered by batteries. To install or replace batteries:
- Assegureu-vos que el mesurador estigui apagat.
- Localitzeu la tapa del compartiment de la bateria a la part posterior del mesurador.
- Utilitzeu un tornavís per obrir el compartiment de la bateria.
- Insert new batteries, observing correct polarity (+ and -). (Typically 2x AAA batteries, refer to the compartment for exact type).
- Tanqueu de manera segura la tapa del compartiment de la bateria.
5. Instruccions de funcionament
5.1 Engegada/apagada
- Per engegar el mesurador, premeu el botó Botó de canvi (red circle button).
- The meter features an auto power-off function to conserve battery life. It will automatically shut down after a period of inactivity.
- Per apagar manualment, premeu i manteniu premut el botó Botó de canvi.
5.2 Mode de mesura automàtic
The meter can automatically identify measured signals and display results. When powered on, it typically defaults to an auto-ranging mode.

Figure 4: The LCD screen displays 'AUTO' indicating automatic measurement mode and 'TRUE RMS' for accurate AC measurements.
5.3 Mesura de corrent altern
Per mesurar el corrent alterna:
- Enceneu el comptador.
- Press the 'Open' button to open the flexible inductor.
- Wrap the flexible inductor around a single conductor of the circuit where current needs to be measured. Ensure the inductor is fully closed around the conductor.
- Read the AC current value displayed on the LCD screen.

5.4 AC/DC Voltage, Resistance, and Frequency Measurement
Per al voltage, resistance, and frequency measurements, connect the test leads (not explicitly shown but implied by 'Port' and 'Multimeter' function) to the appropriate ports and the circuit under test. The meter will automatically detect the measurement type and display the result.
5.5 Funció de retenció de dades
- Premeu el botó Botó HOLD to freeze the current reading on the display.
- Premeu el botó Botó HOLD de nou per alliberar la retenció de dades i reprendre les lectures en directe.
5.6 Retroiluminació i llanterna
- Premeu el botó Botó de retroil·luminació (sun icon) to turn on the display backlight for improved visibility in dim conditions. Press again to turn off.
- Premeu el botó Botó d'il·luminació (light bulb icon) to activate the built-in flashlight. Press again to turn off.

6. Manteniment
6.1 Neteja
Wipe the meter with a dry, soft cloth. Do not use abrasives or solvents. Ensure the meter is powered off and disconnected from any circuits before cleaning.
6.2 Emmagatzematge
When not in use for extended periods, remove the batteries to prevent leakage. Store the meter in a cool, dry place, away from direct sunlight and extreme temperatures.
7. Solució De Problemes
If you encounter issues with your meter, refer to the following common problems and solutions:
- Sense pantalla: Comproveu la instal·lació de les piles i assegureu-vos que no estiguin esgotades. Substituïu-les si cal.
- Lectures inexactes: Ensure the flexible inductor is properly closed around a single conductor for current measurements. Verify correct function selection for other measurements. Check battery level.
- Apagat automàtic: This is a normal function to save battery. Press the Switch Button to turn the meter back on.
