Specification: Product model: 12-60V electricity voltmeter Product material: ABS material Product color: black Product size: 48 x 29 x 22 mm (LWD) Measuring range: 12V-96V Input voltage: 0 (V) Output voltage: 60 (V) Ambient temperature: -10?~65?(?) Voltage measurement error: ±1% 8-stage battery: 10% 25% 40% 50% 60% 75% 90% full Working current: 5--15ma Refresh rate: about 300mS once Display mode: three 0.56 LED digital tube Mounting holes: 46 x 27 mm Feature: 1. Dual display power + voltage at a glance. Display is more intuitive. The upper 8 color bars display (2 red, 6 green) battery power. Downward voltmeter (displaying battery voltage), the decimal point of the voltmeter automatically shifts with higher precision. 2. Wide range of use, lithium batteries, lead-acid batteries, car batteries, electric vehicle batteries, and other types of batteries and electric equipment can be used. The principle of the existing voltage calculation is the same as that of the electric vehicle's power display meter. 3. The meter automatically recognizes the voltage and electricity, and has the function of reverse connection protection (reverse connection will not burn). Instructions for use: The meter head is two-wire system, which can directly test the battery Tips: This scale is suitable for 12V, 24V, 36V, 48V, 60V battery cars, and can also measure lithium batteries, polymer batteries, and nickel-metal hydride batteries. Can also be used for other power/voltage measurement applications.
