Complete setup for efficient testing. This voltage and current signal generator is offered in Type 1 (battery not included) and Type 2 (includes battery), providing a versatile kit for varied testing needs. Userfriendly display. Features a 4digit definition digital tube with brightness adjustable from 1 to 8, ensuring clear visibility in different lighting conditions. Convenient power options. Three power supply methods are supported: external DC 5V, builtin lithium battery, and compatibility with DC 15–30V sources, allowing use in a range of environments. Easy parameter saving. Save voltage and current values with a single encoder click, so you do not need to retune settings after restart. Use scenarios Lab bench testing: quickly set and save stable voltage and current references for electronics projects, motor controllers, or power supply testing. Onsite field service: rely on the Type 2 model with its builtin battery for portable operation without frequent recharging. Prototyping and calibration: repeatably reproduce target voltage/current profiles to validate device behavior and performance during development.
