1. Introdução
The Generic VC6243A is a portable digital LCR meter designed for measuring inductance (L), capacitance (C), and resistance (R). It features a liquid crystal display (LCD) with a 3 1/2 digit readout, double integral A/D conversion, and large-scale integrated circuits for accurate and reliable measurements. This manual provides detailed instructions for the safe and effective use of your VC6243A meter.
2. Informações de segurança
- Certifique-se sempre de que o medidor esteja em boas condições de funcionamento antes de usá-lo.
- Do not attempt to measure circuits with voltages exceeding the meter's maximum input ratings (MAX 36V LCR).
- Avoid using the meter in wet environments or near flammable gases.
- Substitua a bateria imediatamente quando o indicador de bateria fraca aparecer para garantir leituras precisas.
- Do not operate the meter with the back cover removed.
- Use only the specified 9V battery (6F22 type).

- Input Terminals (LCR MAX 36V): Connect the test leads (crocodile clips) here for measurements.
4. Configuração
4.1 Instalação da bateria
The VC6243A meter requires one 9V laminated battery (6F22 type) for operation. The battery is not included with the device.
- Certifique-se de que o medidor esteja DESLIGADO.
- Localize o compartimento da bateria na parte traseira do medidor.
- Use uma chave de fenda para abrir a tampa do compartimento da bateria.
- Insira uma nova bateria de 9V, observando a polaridade correta (+ e -).
- Recoloque a tampa do compartimento da bateria e prenda-a com o parafuso.

5. Instruções de operação
5.1 Ligar/Desligar
Pressione o Interruptor de energia button located on the top right of the meter to turn it ON or OFF.
5.2 Selecting Measurement Function and Range
Rotate the central Botão de alcance to select the desired measurement function (Inductance 'L', Capacitance 'C', or Resistance 'R') and the appropriate range. The meter offers multiple ranges for each function to ensure accurate readings for various component values.
5.3 Zero Adjustment (ZERO ADJ)
Before measuring small inductance or capacitance values, it is recommended to perform a zero adjustment to compensate for residual values in the test leads or meter itself.
- Ensure the test leads are not connected to any component.
- Select the desired L or C range.
- Ajuste o AJUSTE ZERO knob until the display reads as close to zero as possible.
5.4 Realização de Medições
After selecting the function and range, connect the component to be measured to the crocodile clips. The reading will appear on the LCD.
- For Inductance (L): Select an 'L' range (e.g., 200uH, 2mH, 20mH, 200mH, 2H, 20H). Connect the inductor to the test leads.
- For Capacitance (C): Select a 'C' range (e.g., 200pF, 2nF, 20nF, 200nF, 2uF, 20uF, 200uF, 2000uF). Connect the capacitor to the test leads. Ensure the capacitor is discharged before connecting.
- For Resistance (R): Select an 'R' range (e.g., 200Ω, 2kΩ, 20kΩ, 200kΩ, 2MΩ, 20MΩ). Connect the resistor to the test leads.
5.5 Função de retenção de dados
Pressione o DH (Data Hold) button to freeze the current reading on the LCD. Press it again to release the hold and resume live measurements.
5.6 desligamento automático
The meter is equipped with an auto power-off function to conserve battery life. If no operation is performed for a certain period, the meter will automatically shut down. Press the power switch to turn it back on.
