I. Working principle

A sensitive sampling resistor is used to collect the current flowing through the current sensor, convert the current signal into a voltage signal, and then amplify and output a standard signal.

5. The sensor terminal has a built-in removable batterywith a capacityof 1800mAh.
6. The sensor terminal is designed with a hidden buckle sensor interface to support combined experiments with other sensors.
7. The sensor terminal has designed a fixation spot to get itfixed on the iron frameconveniently and combined with traditional lab equipment for experiments.
8. The sensor terminal supports the latest operating systems,such as iOS, Android, windows operating systems, etc.
9. Software with permanent use in digital laboratories in Kazakh and Russian languages. Designed for practical and laboratory work in the physics module of the school curriculum.

IV.Typical applications

This current sensor is used to measure the current at any point in the circuit. Its typical applications are: the properties of series and parallel circuits, measuring the electromotive force and internal resistance of batteries, the volt-ampere characteristics of small light bulbs, Ohm’s law, etc.

V.Caution

This product is suitable for educational use only and is not suitable for industrial, medical, research, or commercial applications.

VI.Usage Tips

1. The usage method is similar to the ammeter. When using it, the current sensor must be connected in series in the circuit. If the current to be measured flows in from the red wire of the current sensor and flows out from the black wire, the displayed value is a positive number; if the connection is reversed, the displayed value is a negative number.
2. The current to be measured cannot exceed the range of the current sensor, otherwise the sensor will be easily damaged!
