Voltage and current signal generator with two flexible configurations: Type 1 (battery not included) and Type 2 (battery included) to fit your testing environment. Key benefits - Clear, reliable readouts: 4-digit high-definition digital tube with brightness adjustable from 1 to 8 for easy visibility in any lighting. - Versatile power options: external DC5V supply, built-in lithium battery, or DC 15-30V input, enabling use on the bench, in the lab, or in the field. - Quick value retention: saving voltage and current values is as simple as one encoder click, so you don’t have to re-tune after restarting. What it supports - Functions as a precise voltage and current signal generator for setup, calibration, and testing tasks. - Compatible with multiple environments thanks to three power methods and the option to choose battery-powered Type 2 or non-battery Type 1. Use scenarios - Bench calibration: set exact voltage/current targets for power rails on development boards and verify responses. - Electronics testing: simulate load conditions and verify regulator behavior during prototyping. - Field verification: use the battery-equipped Type 2 or DC5V/15-30V options to test equipment outside the lab, ensuring stable performance in real-world conditions.
