Specification: Allowable power supply voltage range: 10-15VDC Maximum current consumption: 400 mA Maximum working power: 100W Maximum possible measured power: 150W Minimum power required to start tuning: 5W Minimum possible measured power: 0.1W Measurement resolution of power up to 10W: 0.1W Measurement resolution with power greater than 10W: 1W Power measurement accuracy error: ± 10% Maximum installed inductance: 8.53H inductance Minimum installation step: 0.05H Maximum installed capacity: 1869 pF Minimum capacitance installation steps: 10 pF Typical consumption：100-200 mA Note: In order to protect the environment and save energy, the screen will enter the sleep mode after 10 seconds of inactivity and no emission. At present, the optional functions include 1-5w startup, 10-second screen self-extinguishment/constant light, full automatic/manual mode, etc. This product is started tuning by 1w by default, the screen is always on, and the manual/automatic mode is switched. Manual and automatic mode operation method: Manual mode, that is, press and hold the RESET/TUNE key before the relay can be adjusted. Full-automatic mode, that is, without pressing the key, the system automatically starts to adjust when it detects that the standing wave ratio is greater than 1.3:1 (this value can be adjusted). The parameters used by the product are the main parameters tested by the developer during the software development process, ensuring the reliability of the equipment operation and use in the basic version. Many parameters can be changed by themselves, but they need to be changed carefully to prevent the equipment from being unavailable.
