5. Configuração

5.1 Conexão de Energia

1. Certifique-se de que a chave de alimentação do osciloscópio esteja na posição DESLIGADO.
2. Conecte o cabo de alimentação fornecido à entrada de alimentação CA no painel traseiro do osciloscópio.
3. Conecte a outra extremidade do cabo de alimentação a uma tomada elétrica CA aterrada.

5.2 Conexão e Compensação da Sonda

Oscilloscope probes are crucial for accurate measurements. Proper connection and compensation are necessary.

1. Connect the BNC end of the probe to either the CH1 or CH2 input connector on the front panel.
2. Attach the probe ground clip to the oscilloscope's ground terminal or a known ground point in your circuit.
3. Compensação da sonda: Most probes have a compensation adjustment. To compensate a probe:
   • Connect the probe tip to the probe compensation test point (usually a square wave output on the front panel).
   • Adjust the compensation trimmer on the probe until the square wave displayed on the screen has flat tops and bottoms, without overshoot or undershoot.

6. Instruções de operação

6.1 Ligar/Desligar

Press the power button on the front panel to turn the oscilloscope ON or OFF.

6.2 Basic Waveform Display

1. Connect a compensated probe to CH1.
2. Connect the probe tip to the signal you wish to measure.
3. Pressione o AJUSTE AUTOMÁTICO button. The oscilloscope will automatically adjust vertical, horizontal, and trigger settings to display a stable waveform.
4. Alternatively, manually adjust the VOLTS / DIV knob for vertical scaling, SEG/DIV knob for horizontal scaling, and the TRIGGER LEVEL knob for trigger point adjustment.
