6. Iziqondiso Zokusebenza

This section details the basic operation of the MATRIX APS-4000B.

Umfanekiso 6.1: Iphaneli Yangaphambili Ngaphezuluview
The front panel features a multi-window digital display for voltage, current, power, and frequency. It includes control knobs for adjustment, various function buttons for settings and shortcuts, and the main power switch.

1. Vula/Vala: Press the main POWER switch on the front panel to turn the unit on or off.
2. Setting Output Parameters:
   • Use the push-down infinite coding knob switch to navigate through the display parameters (Voltage, Current, Frequency).
   • Press the knob to select a parameter, then rotate it to adjust the value. Press again to confirm or move to the next digit.
   • The 4-window 5-digit display shows the set and measured values.
3. Izinqamuleli zekhibhodi: Utilize the dedicated shortcut buttons for quick setting of common voltages (110V, 220V) and frequencies (50Hz, 60Hz). These can be self-assembled/configured.
