1. The instrument is not equipped with a high-energy lithium-ion battery by default, but it can be optionally built-in.
2. 5.7-inch 320×240 LCD display, high-speed thermal printer; graphical display, intuitive interface, convenient for on-site personnel to operate and use.
3. Suitable for use in places such as live arrester testing, power outage testing, or laboratory environments.
4. The current and voltage sensors are completely isolated, safe and reliable. Testing A, B, and C three-phase zinc oxide arresters in three separate tests can be saved as one set of test data.
5. The instrument can perform continuous testing, display voltage and current curves, and quickly print data and curves.
6. Equipped with internal memory, it can store 200 sets of test data even when power is off.
7. Optional RS232 communication interface allows testing via a host computer and exporting test data.
8. Anti-interference calculation can be performed to compensate for the deviation of A and C phase currents caused by B phase.
9. High sampling frequency, advanced digital signal processing technology, strong anti-interference performance, and extremely high measurement accuracy.
10. Optional built-in high-energy lithium-ion battery, especially suitable for places without power supply. The instrument only carries low voltage internally, not exceeding 12V, and can work even while charging.
11. Adopts dustproof, waterproof, and anti-corrosion engineering plastic sealed box, small size, light weight, and easy to carry.
