1, Easy Calibration: This meter adopts exquisite SMT technology, so it has good consistency. It is equipped with current calibration potentiometer and zero adjustment potentiometer. If there is any error, you can calibrate it yourself. 2, Simple and Safe Operation: The current sensor adopts a through-hole design, and the wire passes directly through the hole. Current measurement can be performed without damaging or changing the original current circuit. 3, Isolated Design: Since the current sensor is completely electrically isolated from the measured wire, this meter can measure the current on the positive pole, negative pole of the power supply, a certain line at will. The voltage resistance value between the measured wire is up to 2KV. 4, Forward and Reverse Current: Ammeter can measure the line's forward and reverse current, display the positive current in the forward direction (the ammeter's decimal point is always on or off), and display the negative current in the reverse direction (the ammeter's decimal point flashes slowly). 5, Wide Applications: Equipped with two wires to facilitate access to solar energy systems, automotive, battery and motorcycle lines, find out the battery's charging and discharging status, and can also be used for other purposes.

Calibration Method: The relative error between the instrument and the instrument, or the error caused by component aging or environmental temperature changes after long-term use, can be calibrated by the following methods. To obtain a more accurate measurement, it is recommended to preheat for more than 5 minutes before calibration.
Current Calibration: Under the condition that no current flows, use a slotted screwdriver to adjust the zero potentiometer behind the common inductor until the decimal point of the ammeter flashes quickly as the best point; Constant light or no light indicates that the zero point is positive, and slow flashing indicates that the zero point is negative.
Then insert the amplitude modulation potentiometer under the condition of charging half of the actual current value to be measured. the side of the transformer until it is consistent with the standard table.
If the test accuracy is very high, the above two steps can be repeated to obtain higher accuracy.
