Complete setup options This voltage and current signal generator comes in two variants: Type 1 (excluding battery) and Type 2 (including battery). Both provide essential components for efficient testing. Userfriendly display Features a 4digit definition digital tube with adjustable brightness levels (18), ensuring clear visibility in different lighting conditions. Flexible power options Supports three power sources: external DC 5V, builtin lithium battery, and compatibility with DC 1530V sources for use in diverse environments. Easy parameter saving Save voltage and current values with a simple encoder click, so you do not need to reconfigure settings after restart. Use scenarios Inlab calibration and testing: for setting precise voltage and current targets to calibrate power supplies, regulators, or test rigs without repeated adjustments. Prototype and device testing: Ideal for benchlevel experiments and board validation where stable V/I signals are required to verify circuit behavior. Portable field measurements: Type 2 with battery enables onsite testing where mains power is unavailable, maintaining consistent signal generation during fieldwork.
