Compact DC voltage and current source with precise adjustment and portable form factor. Key benefits Precise, adjustable output: DC voltage up to ±10 V with 0.01 V resolution; current output from 0 to 22 mA with 0.01 mA resolution. Both values can be calibrated for accurate results. Simple control: Adjust output using the encoder knob for quick, repeatable setting without complex menus. Clear display options: A small button switches the display between voltage and current. Display modes include 0100 percent or 050 Hz as described in the operating instructions. Portable and compact: Dimensions 3.94' x 2.36' x 0.79' (100 mm x 60 mm x 20 mm) for easy use on a bench or in the field. Specifications at a glance 1.

Function and performance Accurate voltage and current control enables reliable testing of circuits, sensors, and devices. Fine resolution on both voltage and current enhances repeatability in calibration and measurement tasks. Calibration capability ensures long term accuracy and alignment with reference measurements. Use scenarios Electronics prototyping and bench testing: Set precise supply voltages for opamps, microcontrollers, or sensor circuits; monitor current draw for performance analysis. Device calibration and testing: Provide stable bias or drive currents to sensors and actuators while observing realtime voltage or current responses. Education and demonstrations: Show fundamentals of DC regulation, current limits, and voltagecurrent relationships in classroom or workshop settings. Notes on operation Control is via a rear encoder knob for voltage and current adjustments. The display can show either voltage or current, with optional modes for 0100 percent or 050 Hz as described in the instructions. Calibration options are available to maintain accuracy over time.
