4.1 Famoahana sy fisafoana
Upon receiving your UPO1102 oscilloscope, carefully unpack all components and inspect them for any signs of damage. Retain the packaging for future transport or storage.
Fitaovana mahazatra:
- Oscilloscope Probe (UT-P04) x 2
- Tady herinaratra
- USB2.0 Printing Cable
- English Download Guide
- Multi-language Safety Manual
- Calibration Report (COC)
4.2 Fampifandraisana herinaratra
- Ataovy azo antoka fa apetraka amin'ny toerana marin-toerana sy fisaka ary misy rivotra ampy ny oscilloscope.
- Ampifandraiso amin'ny fidirana herinaratra AC eo amin'ny takelaka aorian'ny oscilloscope ny tariby herinaratra omena.
- Ampidiro ao amin'ny fantson-jiro AC izay efa mifandray amin'ny tany ny ilany ilany amin'ny tariby herinaratra.
- Tsindrio ny bokotra herinaratra eo amin'ny tontonana eo anoloana mba hampandehanana ny oscilloscope.
4.3 Fifandraisana sy fanonerana amin'ny Probe
Before taking measurements, it is crucial to compensate the probes to ensure accurate readings.
- Connect a probe to one of the input channels (CH1 or CH2) on the front panel.
- Connect the probe tip to the "Probe Comp" terminal and the ground clip to the ground terminal next to it.
- Tsindrio ny fiara button. The oscilloscope will automatically adjust the settings to display the compensation signal.
- 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.
- Repeat for the second probe if using both channels.

Figure 4.1: Probe Compensation Waveform
A correctly compensated probe displays a clean square wave. Adjust the probe's trimmer if the waveform shows overshoot or undershoot.
