6. 操作手順

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

図6.1: フロントパネルview
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. 電源オン/オフ: 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. キーボードショートカット: Utilize the dedicated shortcut buttons for quick setting of common voltages (110V, 220V) and frequencies (50Hz, 60Hz). These can be self-assembled/configured.
4. メモリ機能（M1-M5）： The unit allows storing up to five sets of frequently used voltage (V) and frequency (F) settings. Refer to the detailed programming manual for saving and recalling these settings with a single key.
5. キーロック機能： To prevent accidental changes to settings, activate the Key LOCK function. This will disable the front panel controls. Refer to the display for 'LocH' status.
6. ソフトスタート機能: The power supply incorporates a soft start function to protect both the unit and the load from sudden current surges upon activation.
7. Measuring Function: The display provides real-time measurements of voltage (Vrms), current (Arms), frequency (Fre), power (Wattage), and power factor (PF).
