"Color will be sent randomly and hope can understanding, if need Black or White color, please contact us, Thanks ^^
Attention:
1.Include a current transformer, no need to buy it separately.
2.Please try not to install the meter and current transformer around the high temperature, strong magnetic field and large transformer, 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 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 dont mix it up when you use it in the later period. If mixed, you need to recalibrate it.
Parameters:
Supply voltage:DC4-30V（Note:The maximum input voltage can not exceed 30V, or be burnt.）
Operating current:<30mA
Test voltage:DC0-100V/300V/600V
Test current:DC0-10A/20A/50A/100A/200A/300A/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
Size: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, dont need to worry about the ammeter ""common ground"".
7.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.
8.It can be tested two ""completely isolated"" devices. The voltage of A device, and the current of the B device. Or the voltage of device B, the current of A device.
9.The withstand voltage value up to 2KV between the tested conductor
10.High reliability, high resistance to current shock, no current impact damage ammeter.
11.With three wires,connection is convenient,easy connect to solar system/car/electric vehicle/motorcycle interior wires. It is used to monitor the battery voltage and can be also used for other products."
