Three Wires LED Digital Voltmeter Ammeter DC 0-300V with Sensor 10A Ampere Meter Volt Amp Panel Meter Voltage Tester 0.39''

AmmetersAttention:1.Include a current 2.Please try not to install the meter and current around the high temperature, strong magnetic fieldand large , otherwise the accuracy will be affected.3.In order to obtain a higher precision measurement, it is recommended to "preheat for 5 minutes" beforeadjusting the calibration.4.Sincethe 24V battery charge full of floating voltage may be over 30V, so "no" recommended direct use it.5.When you select range, not the larger the better. the larger the range, the larger the error, it is recommendedthatit is 1.5 or 2 times as large as the actual test value.6.This meter and CT have been calibrated by the "one to one". Please don't mix it up when you use it in the laterperiod. If mixed, you need to recalibrate it.Technical Parameters:Supply voltage:DC4-30V(Note:The maximum input voltage can not exceed 30V, or be burnt.)<;30mATest voltage:DC0-300VTest current:DC0-10ADisplay type:0.39'' LED with red and greenfonts Measurement rate: 500mS / timeMeasurement accuracy:1% (± 2 digits)CT wire length:150mmTerminal wire length:150mmDimension:70*40*30mmMounting hole:68*38mm.Features:1.The wide power supply range, with reverse polarity protection.2.Display voltage and current on thescreen at the same time.5.CT adopts the design of perforation type wire through the hole,without having to cut wires, without damage,withoutchanging the electric current wire can be achieved current measurements.6.Since CT and measured wire is isolated completely, this meter can be measured the current of the power positive,negative and any devices, don't need to worry about the ammeter "common ground".7.The positive and backward currentcan be measured,and the "positive" current is shown in the positive direction(the decimal point is always bright or not
