૫.૧ ઓસિલોસ્કોપ મોડ

In Oscilloscope mode, the device displays real-time waveforms. Use the following controls:

• CH1/2: Selects the active channel or displays both.
• HOR (Horizontal): Adjusts the time base (horizontal scale) of the waveform.
• Vertical Scale: Use the directional pad (up/down) to adjust the voltage scale for the selected channel.
• Trig/Δ (Trigger): Configures trigger settings (edge, level, mode) to stabilize the waveform display.
• સ્વતઃ Automatically adjusts vertical, horizontal, and trigger settings for a stable waveform display.
• ચલાવો/થોભો: Freezes or resumes the waveform acquisition.

૫.૨ મલ્ટિમીટર મોડ

In Multimeter mode, the device functions as a digital multimeter. Use the directional pad to select the desired measurement function (Voltage, Current, Resistance, etc.). Ensure the test leads are connected to the correct input jacks for the selected measurement type.
