VI-12V1A Portable High Performance Ammeter Accuracy Agility Instrument with Anti-Interference Function

VI-12V1A Portable High Performance Ammeter Accuracy Agility Instrument with Anti-Interference Function

Description:
- VI voltage and current meter: It is a portable instrument that can actively generate the required DC voltage and measure the current size using high-performance processor. Small size, light weight, with the ability to measure small current. The product display screen interface and buttons are clear and simple, and can be set in Chinese or English. It is convenient to use and easy to operate. This voltage-current meter generates a constant voltage output DC voltage and tests the current flowing through it, so that the power and resistance of the parts to be measured can be calculated. The resolution is high, and the measurement result is 6 significant digits. Strong resistance to 50Hz and 60Hz power frequency interference, and digital indication of interference degree.

Note:
- To ensure the accuracy of measurement and calibration, please preheat the product for at least 5 minutes before measurement.
- Disadvantages: the measurement time of large current should not be too long: >0.5A, the continuous duration should be less than 30s (the switch IC may be used for improvement in the future)
- The interface is BNC female. Since the strength of copper is relatively lower than that of other metals, please protect it carefully to avoid falling and bumping damage.
- In the case of strong interference, unconventional operation, and unknown software bug, the numerical display may be abnormal or even crash. At this time, please restart the instrument directly or press "RESET" to reset the product.
- The tested parts cannot be electrified, especially the energy storage devices (such as electrolytic capacitors), which need to be discharged before testing, otherwise the instrument may be damaged.
- During calibration, try to keep away from the electromagnetic interference of the surrounding environment, preferably from the mains, such as wires, sockets, etc.
