4.3 ການເຊື່ອມຕໍ່ Probe ແລະການຊົດເຊີຍ

Before taking measurements, it is crucial to compensate the probes to ensure accurate readings.

1. Connect a probe to one of the input channels (CH1 or CH2) on the front panel.
2. Connect the probe tip to the "Probe Comp" terminal and the ground clip to the ground terminal next to it.
3. ກົດ ອັດຕະໂນມັດ button. The oscilloscope will automatically adjust the settings to display the compensation signal.
4. Observe the square wave displayed on the screen. If the waveform is not a perfect square (over-compensated or under-compensated), adjust the trimmer on the probe body using a non-metallic tool until a flat-top square wave is achieved.
5. Repeat for the second probe if using both channels.
