Amp Volt Watt Kwh Meter Tester Panel 4-in-1 Multimeter for 12V DC 6.5-100V 20A

The digital DC ammeter voltmeter is a 4-in-1 multimeter used for measuring the voltage, current, energy, and active power of electrical devices. The measuring range includes a voltage test range of DC 6.5 to 100V, a current test range of 0 to 20A, an active power test range of 0 to 2kW, and an energy test range of 0 to 9999kWh. However, users should be cautious not to exceed the rated parameters, as the 20A rating is only for short loads, not continuous operation. It is recommended to use the 50A version if the continuous output exceeds 15A.

This multimeter offers a variety of functions, including a large LCD display with backlight, a voltage alarm function, an energy reset function, and data storage when the power is off. It also features a built-in shunt, eliminating the need for an external shunt.

The voltage alarm function allows users to set both high and low voltage alarm thresholds, which range from 6.5V to 99.9V. When the voltage exceeds the set threshold, the backlight and voltage display will flash to alert the user.

The energy reset function enables users to clear the energy value. To do so, the user must hold the key for 5 seconds until the number flashes, then release the key. Pressing the key again will clear the energy value and exit the reset flashing state. If the user does not wish to clear the energy value, they can hold the key for 5 seconds again until the number stops flashing, which means the energy value will not be cleared, and the reset state will be exited.

The backlight function allows users to turn the backlight on or off by pressing the corresponding key. The backlight state will be saved when the power is turned off.

This digital DC ammeter voltmeter is suitable for indoor use only and should not be used outdoors. It can be used to monitor the voltage, current, power, and energy usage of various applications, such as batteries, solar systems, and electric bicycle generators. However, the load should not exceed the rated voltage and current.

The package includes the DC multimeter and a user manual in English. It is important to note that the wiring must be connected according to the provided wiring diagram, as improper connection can result in the product burning out or not functioning correctly.

In summary, this 4-in-1 digital DC ammeter voltmeter offers a range of functions, including voltage, current, energy, and active power measurement, as well as voltage alarm, energy reset, and backlight control features. It is suitable for indoor monitoring applications, but users must ensure that the load does not exceed the rated parameters.
