4. Käyttöohjeet

4.1. Oskilloskooppitila

Oskilloskooppitoiminto mahdollistaa sähköisten signaalien visualisoinnin ja analysoinnin ajan kuluessa.

1. Oskilloskooppitilaan siirtyminen: The device typically defaults to oscilloscope mode upon startup. If not, navigate to it via the MENU button.
2. Antureiden kytkeminen: Connect the oscilloscope probes to the CH1 and/or CH2 BNC connectors. Connect the ground clip of the probe to the circuit's ground.
3. Adjusting Vertical Scale (Volts/Div): Use the navigation buttons to adjust the vertical sensitivity (V/div) for each channel (CH1, CH2) to fit the signal on the screen.
4. Adjusting Horizontal Scale (Time/Div): Adjust the horizontal time base (s/div) to view the desired number of signal cycles.
5. Laukaisu:
   • Paina LAUKAISTA -painiketta päästäksesi liipaisimen asetuksiin.
   • Select trigger mode (Auto, Normal, Single) and trigger type (rising edge, falling edge).
   • Adjust the trigger level to stabilize the waveform.
6. Automaattinen asetus: Paina AUTO button for automatic scaling and triggering of the input signal.
7. Mitat: Käytä PRM (Parameter) button to display automatic measurements (e.g., Vpp, Vrms, Frequency).
8. Aaltomuotojen tallentaminen: Paina TALLENTAA button to capture the current waveform as a screenshot.

4.2. Yleismittaritila

The multimeter function allows for precise measurement of various electrical parameters.

1. Entering Multimeter Mode: Navigate to multimeter mode via the MENU button.
2. Mittausjohtojen kytkeminen:
   • Voltage, resistance, frequency, diode, and continuity: Connect the red lead to the VΩ-Hz jack and the black lead to the COM Jack.
   • For current (mA): Connect the red lead to the mA jack and the black lead to the COM Jack.
   • For high current (10A): Connect the red lead to the 10A jack and the black lead to the COM Jack.
3. Mittaustoiminnon valitseminen: Use the navigation buttons to select the desired measurement function (e.g., DC Voltage, AC Voitage, Resistance, Capacitance, Diode Test, Continuity Test, Temperature).
4. Mittojen ottaminen: Apply the test leads to the circuit or component under test. The measurement will be displayed on the screen.

4.3. Signal Generator Mode

The signal generator function allows for the output of various waveforms for testing purposes.

1. Entering Signal Generator Mode: Navigate to signal generator mode via the MENU button.
2. Lähdön kytkentä: Connect a test lead from the signal generator output (often shared with a multimeter input, refer to specific port markings on the device) to the circuit requiring the signal.
3. Aaltomuodon valinta: Choose the desired waveform type (e.g., Sine, Square, Triangle, Pulse, Arbitrary) using the navigation buttons.
4. Parametrien säätäminen: Aseta taajuus, amplitude, and offset of the generated signal as required.
