Mini SWR 0-100W 1.8M-30M HF Short Wave Standing Wave Meter SWR Power Meter + OLED + Battery

Description The product performs 1024 point interpolation algorithm correction on the nonlinearity of the diode on the software and can simultaneously display the standing wave peak forward power peak reverse power average forward power and average reverse power Usage method The left m base of the standing wave meter is the input terminal connected to the radio station and the right m base is the output terminal connected to the antenna Turn the power switch on the right side of the standing wave meter When the standing wave meter starts up first display the world map then display the version number and the percentage value of battery voltage and then enter the main measurement interface At this time if there is a signal the standing wave and corresponding power value will be displayed The charging LED indicates that it is always on during charging and goes out after charging In case of input overvoltage output undervoltage and overvoltage output short circuit and timeout of charging time it flashes at the frequency of 1 6hz Do not charge your wife after the battery port is exhausted If the battery is exhausted and the standing wave meter cannot be started for charging the red LED indicator in the charging port will be dark At this time do not unplug the charging plug After a few minutes plug and unplug the charging plug several times When the charging light is normal brightness it will enter the normal charging state Specification Frequency ra
