Functional details and operating modes

• Three regulated sources: a low‑voltage source covering the 0–6 V range and two higher‑voltage sources covering ±25 V ranges; the ±25 V sources can operate in fixed tracking (mirrored rails) or variable tracking ratio modes for asymmetric rails.
• Current limiting operation: Each source supports current limiting; the manual describes procedures for using current limiting both in constant‑voltage and tracking modes.
• Calibration and adjustments: The manual includes step‑by‑step calibration procedures for meter zero, voltmeter, and ammeter adjustments.

Controls and connectors

• Front panel: Voltage and current knobs (coarse/fine style on some models), selector switches for ranges and tracking mode, and panel meters for readout.
• Output terminals: Standard bench supply terminals; the manual lists safe connection practices and terminal ratings.
