Display and Control
Connection:
§ Power Supply: DC 8V-10V, recommend DC 9V, no more than 10V
§ Probe: connect the probe to BNC
Operation:
Button Functions:
【V/DIV】: Selection for Sensitivity and Vertical position
【SEC/DIV】: Selection for time base and horizontal position,
【TRIGGER】: Selection for Trigger mode, Trigger Level or Trigger Edge
【OK】: Press once to entert HOLD function, second press to exit HOLD function
【ADJ】: Arrow key, turn left and right to select parameters Selected parameter will be highlighted
【COUPLING SWITHC】: Coupling can be switched to DC, AC or GND. When it is switched to GND, the oscilloscope’s input is disconnected from external input and is connected to the ground, aka input is 0 V
Additional Functions:
Vertical position alignment Switch to GND:press【V/DIV】for 3 secondsParameter bar turn on/off:Press【OK】for 3 seconds to turn on/off the parameter bar.Save waveform:Press 【OK】and 【TRIGGER 】at the same time, current waveform will be saved in EEPROM; the original data will be replaced.Read waveform:Press【OK】and【SEC/DIV】at the same time, it can read the waveform saved in EEPROM; it is showed in HOLD mode.Reset to default setting:Press【SEC/DIV】and【TRIGGER】for 3 secondsHorizontal position centered:Press【SEC/DIV】for 3 seconds, horizontal position will be in the center of waveform bufferTrigger level centered:Press【TRIGGER】for 3 seconds, Trigger level will be in the center of Signal amplitude.Probe-compensated adjustment:Adjust trimmer capacitor C3 and C5:a) Connect the probe’s RED clip to signal output terminal, black clip not connectedb) Power on the oscilloscope to start, press【ADJ】knob for 3 seconds. Tthe bottom of the screen shows the output of the test signal amplitude, and then press【ADJ】 to adjust amplitude to 0.1V.c) Set sensitivity to 50mV, adjust trigger level to make the waveform stable.d) Adjust C3 to make the waveform right-angled. C3 adjustment is finished.e) Press【ADJ】to adjust amplitude to 3.3V, and set sensitivity to 1V, adjust C5 to make the waveform right-angled.Package included:1*DSO328 2.4" TFT LCD Digital Oscilloscope Test 1Msps 200KHz Bandwidth
