S/N | Function |
1 | Built handle, that is, does not occupy space and convenient for users to carry instruments. |
2 | 10.4-inch LCD touch color screen, multi-power intuitive display, full touch screen operation, more convenient operation. |
3 | The folding foot can raise the instrument by about 15° for optimal operation and reading view. |
☆ W ide R ange of C urrent M easurement |
Each phase is equipped with a pair of fast terminals and wires, and the ac current of 0.2 mA ~120 A can be measured by direct connection, simplifying the wiring operation.
Fully automatic switching range, the transformer does not shift at one time, no matter in which range suddenly into the large current will not lead to damage or measurement accuracy reduction. The minimum measurement is limited to 0.2 mA, which can assess the accuracy and stability of the power / electric power of the R46 electric power device and its standard meter at the minimum starting current of 0.3 mA. |
☆ High R eliability of the I nstrument |
There is complete electrical isolation between the voltage and current measurement circuits; in the limit state (500 V, 100 A), it will not damage the instrument, and can ensure the accurate value.
|
☆ Easy to U se O n-site |
The main weight of the instrument is 9.9 kg and equipped with a special pull rod instrument box, which can put the host, test wire and laptop computer in it, and the transportation is very convenient. The notebook is equipped with special software meeting the requirements of JJG 597, which can automatically complete the error analysis, data recording, export or printing certificate of the device on site. |
