Gauges************************************************************************************************************************************************************************YB27VA DC0-100V 300V LED Digital Voltmeter Ammeter 999mA 10A 20A 50A 100A Amp Volt Voltage Current Meter Tester Dual LED DisplayAttention:1,9.99mA, 99.9mA, 999mA, 2A, 5A, 10A, 20A direct test, the shunt is built in.2,More than 10A(except for 20A direct test) ,you must use a shunt to work,even 0.1A, or it will be burnt.3,More than 10A(except for 20A direct test) ,the shunt is not built in,you need to buy it separately. (1)If you have a shunt , please note your shunt specification (standard is 75mV, if no notes, all according to 75mV delivery) (2)If you don't have a shunt, please order the corresponding shunt, we will not notice at the time of shipment.4,Because the 24V battery charge full of floating voltage may be more than 30V, so "no" recommended direct use 24V battery.5,In the following circumstances, it is strongly recommended to choose: isolation meter (isolated power supply meter):(1) When two or more meters are installed on a device. (2) Can not be isolated power supply.Technical Parameters: Dimension:48*29*21mmSupply voltage:1.Standard:DC3.5 30V(Note:The maximum input voltage can not exceed 30V, or be burnt.)2.Isolation meter:DC8-18V<;20mA; <;200mADisplay mode: 0.28 "LED, single color or double color:(red-red) Both voltage and current are red color(red-blue):Voltage is red,current is blue. Measurement rate: 500mS / timeMeasurement accuracy: 1% ( 2 digits) Mounting dimension: 45.5*26.5 mm
