VAT1200 100V 200A Wireless Ammeter Voltmeter Battery Capacity Monitoring Coulomb Counter 12V 24V 48V Color Screen Meter ,Easy to Install

The display module shell adopts sandblasting oxidation technology, which is beautiful and elegant. The buttons use touch buttons with features of high sensitivity and long service life. The measurement module needs to be connected in series to the circuit under test, and the measured data is sent to the display module for display. The data between them can be transmitted via USB cable (1 meter long), it can also be wirelessly transmitted through the built-in wireless module. The wireless transmission distance is up to 10 meters. The measuring module can detect the current in both directions. It is not necessary to change the wiring mode during the charge and discharge of the battery, and the wiring is convenient.(In battery charging mode, the current value is preceded by a "-" as a marker to distinguish it from the battery discharge mode). The instrument adds self-calibration function to solve the problem of zero drift in old products. After a long time of work, the current and capacity can still maintain a good accuracy. The display has three display interfaces. The default display is the large font mode, which displays the main parameters of voltage, current, capacity, temperature, etc. Press any key to switch to the full-function display mode. Under the full-function interface, you can set the required parameters, and you can also set a black display on white mode, and the display can be seen under sunlight.
