5. Asennus

Follow these steps to set up your Luqeeg MHS5200A:

1. Liitä virta: Plug the DC5V power adapter into the DC5V input port on the rear panel of the device, then plug the adapter into a suitable power outlet.
2. Virta päälle: Flip the ON/OFF switch on the rear panel to the 'ON' position. The LCD display should illuminate.
3. Yhdistä tietokoneeseen (valinnainen): If you plan to control the device via software, connect the USB cable from the device's USB port to your computer. Install any necessary drivers or software from the provided CD or manufacturer's websivusto.
4. Connect Output Cables: Connect BNC cables to the CH1 and/or CH2 output ports as needed for your application. Connect the other end of the cables to your oscilloscope, circuit, or other test equipment.
5. Connect External Input (Optional): If using the frequency counter function, connect the external signal source to the Ext.IN BNC connector.

6. Käyttöohjeet

6.1 Peruskäyttö

1. Valitse kanava: Paina CH1/2 button to select either Channel 1 or Channel 2 for adjustment. The active channel will be indicated on the display.
2. Valitse aaltomuoto: Paina AALTO -painiketta. Käytä SÄÄTÄÄ knob to scroll through available waveform types (Sine, Square, Pulse, etc.). Press OK vahvistaaksesi valintasi.
