DC 0-100V LED Dual Voltmeter Ammeter Digital Voltage Current Meter Tester Current DC 10A 20A 50A 100A 200A 300A 500A(Red-Red,DC10A)

AmmetersAttention: 1.Include a current , 2.Please try not to install the meter and current around the high temperature, strong magnetic field and large , otherwise the accuracy will be affected. 3.In order to obtain a higher precision measurement, it is recommended to "preheat for 5 minutes" before adjusting the calibration. 4.Since the 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 recommended that 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 later period. If mixed, you need to recalibrate it. Product Features: The wide power supply range, with reverse polarity protection. Display voltage and current on the screen 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. The tolerance is absolutely exit. CT adopts the design of perforation type wire through the hole, without having to cut wires, without damage, without changing the electric current wire can be achieved current measurements. 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". The positive and backward current can 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, an
