4. Configuració

Follow these steps to set up your Irfora Bench Digital LCR Meter for first use.

1. Desembalatge: Carefully remove the LCR meter and all accessories from the packaging. Verify that all items listed in the package list are present: Bench Digital LCR Meter, Kelvin Alligator Clip, 2 Fuses, Power Cord, User Manual (English).
2. Connexió d'alimentació:
   • Assegureu-vos que el voltage selector (2 on Figure 3.3) on the rear panel is set to the correct voltage for your region (AC 200-240V).
   • Connect the provided power cord to the power supply plug base (1 on Figure 3.3) on the rear panel of the meter.
   • Connecteu l'altre extrem del cable d'alimentació a una presa de corrent amb connexió a terra.
3. Encesa inicial: Press the power switch (1 on Figure 3.2) located on the front panel to turn on the device. The LCD screen (2 on Figure 3.2) will illuminate and display the startup sequence.
4. Connexió dels cables de prova: Connect the Kelvin Alligator Clip to the grounding and test terminals (3 on Figure 3.2) on the front panel. Ensure a secure connection for accurate measurements.

5. Instruccions de funcionament

This section details the basic operation and advanced functions of the LCR meter.

5.1 Mesura bàsica

1. Encès: Turn on the LCR meter using the power switch.
2. Component de connexió: Connect the component to be measured to the Kelvin Alligator Clip.
3. Select Measurement Function: Use the function keys (4 on Figure 3.2) to select the desired measurement parameter (L/C/R/Z). The primary and secondary parameters (X/D/Q/θ/ESR) will be displayed automatically.
4. Ajust de freqüència: Premeu el botó FREQ button to cycle through available test frequencies (100Hz, 120Hz, 200Hz, 400Hz, 800Hz, 1KHz, 2KHz, 4KHz, 8KHz, 10KHz, 15KHz, 20KHz, 40KHz, 50KHz, 80KHz, 100KHz).
5. Adjust Test Level: Premeu el botó NIVELL button to select the desired test signal level (100mV, 300mV, 600mV, 1000mV, 1500mV, 2000mV).
6. Llegir mesura: The measurement results will be displayed on the 3.5-inch LCD screen.

5.2 Funcions de correcció

The meter supports Open Circuit Correction and Short Circuit Correction to improve measurement accuracy, especially for low-value components or long test leads.

• Open Circuit Correction: Sense cap component connectat als terminals de prova, premeu el botó CAL button and follow the on-screen prompts for open circuit correction.
• Short Circuit Correction: Short the test terminals together (e.g., using a shorting bar or by touching the alligator clips together), then press the CAL button and follow the on-screen prompts for short circuit correction.

5.3 Screening and Comparator Functions

The screening function allows setting tolerance levels for component sorting, while the comparator function enables automatic sorting into qualified and failed bins.

• Tolerance Setting: Utilitza el TOL% button to set tolerance levels from -100% to 100%, with fixed points at 10%, 25%, and 50%.
• Comparator Sorting: The comparator function offers 5 gear sorting, including 3 qualified gears, 1 failed gear, and 1 ancillary gear. This is particularly useful when using the Handler interface for automated testing.

5.4 Interfícies de comunicació

The meter is equipped with USB, RS232, and Handler interfaces for remote control and data acquisition.

• Interfície USB: Connect the meter to a computer via the USB port (4 on Figure 3.3) for data logging and remote control using compatible software.
• Interfície RS232: The RS232 port (3 on Figure 3.3) allows for serial communication with external systems.
• Handler Interface: The Handler interface (5 on Figure 3.3) is designed for integration into automated test systems, facilitating rapid component sorting based on set criteria.

6. Manteniment

Proper maintenance ensures the longevity and accuracy of your LCR meter.
