• You can select from two power supply methods : internal battery power or external DC adaptor power. Power supply voltage of the DC adaptor is grid voltage. After connecting to power, start the self calibration process by pressing the [USER] button then [F3]. This will ensure optimal performance. Accessing signals • Press UTILITY but ...

Using the Autoset function • Connect the signal to be measured to the signal input channel. • Press AUTO and the oscilloscope will scan the time base and trigger mode and set the vertical deflection factor. You can manually adjust further after this process to get the optimum display. Vertical control • Pressing the key to a ...

Channel A, Channel B and shifting signals vertically • Each channel has its own menu. Set up each item for each channel individually. Press the [A] or [B] function key and the system will display the operation menu for Channel A or Channel B. Resetting the Instrument • To use factory setup, follow the steps below ...

attenuation factor to keep the reading of the signal being measured correct. Polarity Normal Invert Normal waveform display Waveform is inverted Setting channel coupling • To apply a signal to Channel A. The signal being tested is a sine signal that contains DC quantities. � ...

• Bias voltage is suitable for observing the following signals: • The input signal is made up of relatively high DC quantities and relatively low AC quantities. • The input AC signal is very low in frequency and contains DC quantities. AC mode is unsuitable. • Duty ratio of the signal is too small. Waveform details are hard to ...

• Triggering decides when the oscilloscope collects data and display waveforms. Once the trigger is correctly set up, it can transform unstable displays into meaningful waveforms. • When beginning to acquire data, the digital storage oscilloscope first collects sufficient data required for drawing a waveform on the left side of the ...
