JS-VISG-M-S is a handheld Voltage and Current Signal Generator
used primarily for debugging industrial automation equipment like PLCs, inverters, and servo motors. Below is a structured write-up based on its technical manual and operational specifications. Product Overview JS-VISG-M-S
(often branded under manufacturers like Brightwin) is designed as a portable tool for simulating analog signals (
). It is powered by a micro-USB interface or an internal battery, featuring a digital display for real-time monitoring. Key Features Dual Mode Output: Capable of generating both active current ( ) and voltage ( ) signals. Multiple Power Options: Supports Micro-USB power or internal lithium battery charging. Precise Adjustment: js-visg-m-s manual
Features a high-precision encoder knob with "Fine" and "Rough" adjustment modes. Customizable Display:
Users can toggle between actual values (Voltage/Current), percentage ( ), or frequency ( Operational Settings (Quick Reference)
The device uses a menu system (F-codes) to define its behavior: F001 (Adjustment Mode): Toggle between Rough ( ) and Fine ( ) adjustment. F002 (Output Range): Sets the voltage range (e.g., F003 (Display Mode): Switches display between value, percentage, or Hz. Password Protection: JS-VISG-M-S is a handheld Voltage and Current Signal
To enter certain advanced parameter settings, users must rotate the knob to enter the password sequence: Wiring & Troubleshooting Connection Type Instruction Active Current Output to the signal input ( Voltage Output to the signal input ( Verification Test resistor to the output. The generator is working if Safety & Maintenance Lethal Voltage Warning:
Never open the instrument while connected to a primary power source to avoid electrical shock. Port Protection:
Do not connect the output terminals to energized external circuits. Chapter 2: Installation Methods The js-visg-m-s library can

The js-visg-m-s library can be integrated via three primary methods. Choose the one that aligns with your build pipeline.
js-visg-m-s is a lightweight, modular JavaScript library designed for creating interactive visualizations from multiple data sources (APIs, static files, streaming data). It supports:
Use cases: dashboards, monitoring tools, research data comparison.
