_x000D_ _x000D_ 1. Two-way detection of current, it is convenient for users to detect charging and discharging to detect bidirectional current without changing the wiring direction. 2. power-off memory function, after power-off can remember the number of AH and WH before power-off, convenient observation and measurement. 3. time and AH number clear function, does not affect the next measurement. 4. AH number can be filled up, does not affect direct discharge measurement. 5. voltage, current, charging capacity AH number, WH number, time, power display at the same time, the display information is comprehensive and clear. 6. with output shutdown function button, flexible to open or shut down the output. 7. with overvoltage, overcurrent, over temperature and other protection functions. 8. online calibration, to facilitate customers to correct errors in a timely manner. 9. Turn off the LCD display when necessary to reduce product power consumption. The VA75010s is a multi-function meter that can display various physical parameters such as voltage, current, power, capacity, energy, temperature and running time in real time. Over-voltage, under-voltage and over-current can be realized through the reserved relay interface. Temperature protection.Moreover, the meter uses a 1.8-inch color liquid crystal as a display, and the display data is more comprehensive, clear, and easy to observe.This instrument is perfect for applications that require monitoring of output voltage and current, as well as charging and discharging the battery. Colour: Black Material: ABS Package Contents: 1 x Voltage and current meter 2 x Single head line Only the above package content, other products are not included. Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm. _x000D_
