6. Betjeningsvejledning

6.1 Powering On/Off Output

Tryk på ON/OFF button to enable or disable the output power. When the output is off, the display will show 0.00V and 0.000A.

6.2 Indstilling af udgangsvolumentage (CV Mode)

1. Tryk på V-SET knappen. Lydstyrkentage value on the LCD will start blinking.
2. Drej på MENU knap til at justere den ønskede lydstyrketage. Press the knob to confirm the setting.
3. Alternatively, use the directional buttons (M1-M4) to select digits for finer adjustment.

6.3 Setting Output Current Limit (CC Mode)

1. Tryk på I-SET button. The current value on the LCD will start blinking.
2. Drej på MENU knob to adjust the desired current limit. Press the knob to confirm the setting.
3. This sets the maximum current the power supply will deliver. If the load draws more current, the unit will switch to Constant Current (CC) mode and maintain the set current.

6.4 Setting Protection Parameters (OVP/OCP)

The WZ5005 includes Over-Voltage Protection (OVP) and Over-Current Protection (OCP) to safeguard your equipment.

1. Tryk på P-SET button. The OVP value will blink.
2. Drej på MENU knob to set the desired OVP threshold. Press the knob to confirm and move to OCP setting.
3. Drej på MENU knob to set the desired OCP threshold. Press the knob to confirm.
4. Hvis output voltage or current exceeds these set values, the power supply will automatically shut off the output to protect the connected device.

6.5 Tastlåsfunktion

To prevent accidental changes to settings, the WZ5005 features a key lock function.
