Advanced protection and charging management The adjustable signal generator includes short circuit protection for the output, reversed connection protection for the power supply, and overcurrent protection during battery charging and discharging. It also features an automatic charging management system with a power indicator to provide clear feedback on charging status and safety during use. Versatile and precise signal generation This handheld generator delivers precision performance for voltage and current signals, with 0 10V/5V voltage and 0 4 20mA current output options. It offers multiple output ranges, with a factory default of 0 10V/0 20mA, and supports display modes to suit different testing needs. Easy to use and adjustable Voltage and current adjustments can be switched at the touch of a button, and wiring can be configured independently for simultaneous output. It provides coarse/fine 2 mode adjustment, an adjustable rotation number setting. Sturdy, ergonomic construction The Current Voltage Analog Simulator features a slim matte anti slip shell for comfortable handling, an elegant aluminum alloy knob, and electroplated buttons for durable, attractive operation. It is built from sturdy plastic material and measures 100x60 mm. Practical use scenarios 1) Bench testing and calibration of sensors and microcontroller projects: simulate 0 10V or 0 20mA signals to verify input channels and control loops. 2) Battery charging/discharging testing: use built in protections and automatic charging management to safely evaluate charging circuits and power management hardware. 3) Prototyping and debugging analog interfaces: quickly adjust voltage and current with coarse/fine controls to explore response ranges and system behavior.
