• Note: If default language is CN, please long press the “Down” key to enter menu mode, then press “down” key again to choose “setup”; press the knob to enter the setup menu > sys-setup, where you can set the language to EN.
• ALL IN ONE SIGNAL SIMULATOR: Signal Generator generates precise DC voltage (±12V), current (0-24mA), and PWM pulse signals (1-150kHz frequency, 0-100% duty cycle), perfect for simulating sensor outputs, calibrating transmitters, controlling valves, and testing PLC/DCS systems
• TRIPLE POWER SUPPLY & PORTABLE DESIGN: Signal Generator runs on its built-in 1500mAh rechargeable lithium battery (1-5 hours of use), via a standard USB-C connection (use while charging), or with an external 24V DC power source, of compact and lightweight design, ideal tool for both benchtop and field work
• HIGH PRECISION & ROBUST PROTECTION: Calibrated for high accuracy (0.03V for voltage, 0.05mA for current), Signal Generator ensures reliable and repeatable results, equipped with short-circuit, reverse polarity, and overcharge protections to keep both the generator and your connected devices safe during operation
• INTUITIVE HD COLOR DISPLAY & EASY CONTROL: Signal Generator features a 2.0" TFT color screen that displays real-time voltage, current, and PWM values at a glance, also allowing you to adjust settings with precision using the premium digital encoder knob and responsive plated buttons
• CUSTOMIZABLE OUTPUTS & SMART MEMORY: Easily set common industrial ranges like 4-20mA, 0-10V, or 0-5V - Analog Signal Simulator can also display corresponding engineering values (e.g., pressure, temperature) and automatically saves your last output setting upon power-off, streamlining your workflow
• Important Note: The PWM output high level is fixed at 5V, NOT suitable for directly driving systems that require 12V or 24V PWM signals, as 5V would be interpreted as a low level in those applications
