DC LED Dial Display 50A Current Portable Accurate with Hall r for Vehicles

DC with Hall r LED Dial Display 50A High Accuracy Current for Vehicles

Feature:

1. Easy Calibration: This meter adopts exquisite SMT technology, so it has good consistency. It is equped with current calibration potentiometer and zero adjustment potentiometer. If there is any error, you can calibrate it yours.2. Simple and Safe Operation: The current r adopts a through hole design, and the wire directly paes through the hole. The current measurement can be realized without damage or changing the current circuit.3. Isolated Design: Beca the current r is completely electrically isolated from the measured wire, this meter can measure the current of the positive pole, negative pole of the power supply, a certain line at will. The voltage withstand value between the measured wire is up to 2KV.4. Forward and Re Current: can measure the forward and re current of the line, display the positive current in the forward direction (the decimal point of the is always on or off), and display the negative current in the re direction (the decimal point of the fes slowly).5. Wide Applications: Equped with two wires to facilitate acce to solar energy system, car, battery car and motorcycle lines, timely grasp the charging and discharging status of battery, and can also be d for other purposes.

In order to oain more accurate measurement, it is recommended to preheat for more than 5 minutes before calibration.Current Calibration: Under the condition that there is no current flowing, a slotted screwdriver to adjust the zero potentiometer behind the mutual inductor until the decimal point of the fes quickly as the best point; Constant light or no light indicates that the zero point is positive, and slow fing indicates that the zero point is negative.Then, under the condition of loading half of the actual current value to be measured, adjust the amplitude modulation potentiometer on the side of the nsformer until it is consistent with the standard table.If the test accuracy is very high, the above two steps can be repeated to oain higher accuracy.
