Sensor DC 20A DC Voltage Current Meter 0-100V 300V 600V LED Digital Voltmeter Ammeter Voltage Tester Meter(DC100V)

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 recommendedthat it 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..Product Features:The wide power supply range, with reverse polarity protection.Display voltage and current on thescreen at the same time.Use the SMT technology, so consistency is very good.With a voltage calibration potentiometer, current calibration potentiometer, you can calibrate by yourself.Thetolerance is absolutely exit.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.Since CT and measured wire is isolated completely, this meter can be measuredthe current of the power positive,negative and any devices, don't need toworry about the ammeter "common ground".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 bright), and the "negative" current is shown in the reverse direction (the decimal point flashes slowly.It can be tested two "completely isolated" devices. The voltage of A device, and the current of the B device
