---------------------------------------------------------------------- 【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.

【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary.

【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product.

【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. ---------------------------------------------------------------------- 6-in-1 Digital Multimeter Voltmeter. Active power is calculated as follows: P = U/I cos, where cos is the power factor. For purely resistive loads (such as incandescent lamps and heaters), the power factor is usually close to 1. Test inductive or capacitive loads (such as refrigerators, washing machines, TVs, and computers). P = U/I less than U. Main Features: Electrical parameter measurement (voltage, current, active power, and power). Overload alarm (backlight and power flicker). Manually set power alarm threshold preset. Power button clear function. Power-down data storage function. Large LCD full display (displays voltage, current, active power, and power). Backlight. Display interface: Voltage, current, power, and energy parameters are all displayed simultaneously. Specifications: Size: 90 x 54.5 x 28 mm Weight: 20A DC voltmeter 78g, 100A DC voltmeter 114g Applicable to power grid voltage range: 110 - 220 V Operating voltage: 85 - 250 VAC Test voltage: 85 - 250 VAC
