5. Nastavení

5.1 Počáteční zapnutí

1. Connect the power cord to the oscilloscope and a suitable power outlet.
2. Stisknutím tlačítka napájení zapněte zařízení.
3. The 7-inch TFT-LCD display will illuminate, showing the OWON logo and then the main waveform interface.

5.2 Kalibrace sondy

Before taking measurements, it is crucial to calibrate the oscilloscope probes for accurate readings. This process compensates for any slight variations in the probes as supplied.

1. Connect a probe to one of the BNC input connectors (e.g., CH1).
2. Ensure the probe's attenuation switch (usually on the probe body) is set to 10x.
3. Connect the probe tip to the test point, which is a small metal loop located on the bottom right of the oscilloscope's front panel.
4. Attach the black grounding alligator clip of the probe to the lower metal loop, which serves as the ground test point.
5. Stiskněte tlačítko Automatické nastavení button on the oscilloscope. The device will automatically adjust settings to display the test signal. The test point outputs a 1 kHz, 5V square wave.
6. Observe the waveform on the screen. If it does not appear as a perfect square wave (e.g., rounded corners or overshoot), use the supplied probe adjustment tool (small screwdriver).
7. Carefully insert the screwdriver into the compensation screw on the BNC connector of the probe and adjust it until the displayed square wave is clean and flat on top and bottom, with sharp corners. A slight turn (approximately 1/8th) may be sufficient.
8. Repeat this process for all probes you intend to use.
