Features:1. The transmitter integrates the function of AC and DC voltmeter, which can linearly measure AC and DC voltages from 12 to 400V.2. The transmitter screen can display the preset transmission power, transmission code - own battery power - detected mains voltage - detected AC and DC mains voltage - and the warning symbol of mains voltage.3. The transmitter has a self-checking function to detect its own working conditions and display it on the LCD screen for user reference.4. The receiver sensitivity can be adjusted manually or automatically, and the receiver can automatically scan the frequency.5. Both transmitter and receiver can work in silent mode.6. Additional transmitters can be used to expand or differentiate multiple signals.7. Automatic shutdown within 10 minutes; flashlight function; backlight function; mute function.Description:1.
