[0016] Among them, the test instrument shell 1 and the microampere ammeter 3 form a complete shell with a cavity inside.
[0017] Among them, the connection between the microampere ammeter 3 and the test instrument shell 1 is sealed inside by wrapping waterproof tape and glue.
[0018] Among them, the test instrument shell 1 and the microampere ammeter 3 are detachably connected.
[0019] Among them, the button of the button charger 2 is arranged on the upper side of the test instrument shell 1.
[0020] The working principle of the utility model is: first, the microampere ammeter 3 is zeroed by using the zero setting knob 4, then the antenna feeder is connected to the antenna feeder water test instrument through the n type interface 5, because two metals with different potentials will produce current when put into electrolyte, when the microampere ammeter 3 pointer produces obvious deflection, it proves that the antenna feeder is waterlogged. When the electrolyte concentration is too low, the current generated is too small to make the microampere ammeter 3 produce deflection, press the button of the button charger 2 for three seconds to charge, make the microampere ammeter 2 pointer produce deflection, then loosen the observation pointer to return to normal, because the pointer return speed is different when the original battery and the capacitor discharge, when the pointer returns to normal, it is the capacitor discharge characteristic, which proves that there is no electrolyte, that is, the antenna feeder is not waterlogged, on the contrary, when the pointer return speed curve changes, it is the battery discharge characteristic, which proves that there is electrolyte, that is, the antenna feeder is waterlogged.
