Two Wires DC Digital Voltmeter Ammeter Sensor 500A DC Voltage Current Meter DC 5-100V Amp Volt Panel Meter Volt Tester(Black Cover)

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. Technical Parameters: <;30mA Test voltage:DC5-100V Test current:DC0-500A Display type:0.39'' LED with red and green fonts Measurement rate: 500mS / time Measurement accuracy:1% (± 2 digits) CT wire length:150mm Terminal wire length:150mm Dimension:70*40*30mm Mounting hole:68*38mm Features: 1. The wide power supply range, with reverse polarity protection. 2.Display voltage and current on the screen at the same time. 3.Use the SMT technology,so consistency is very good. 4.With a voltage calibration potentiometer, current calibration potentiometer, you can calibrate by yourself. The tolarance is absolutely exit. 5.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. 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
