Hundred test brand transformer DC resistance fast speed measurement using high-frequency modulation high-power power supply, high-speed A / D converter and programmable current source technology, to achieve up to 20A of current output, to achieve an unprecedented rapid measurement and highly automated measurement capabilities, The instrument has the characteristics of high precision, stable data, good repeatability, strong anti-interference ability, perfect protection function, and fast charging and discharging speed. The instrument has the characteristics of small size, light weight, easy to carry, etc. It is the latest generation of rapid test of DC resistance of transformers.
Features:
1, using high-speed 16-bit A / D converter, measuring data stability, good repeatability.
2. Automatic program-controlled current source technology, which can not only select the typical value output current manually, but also can automatically control the output current by the internal microcontroller. There are a total of 2,000 current levels in the current source. In the automatic state, the internal microcontroller is used by the internal microcontroller. The resistance is automatically controlled to achieve a wide measurement range and the best measurement conditions.
3, real-time dynamic display, fast response, in the measurement state can be directly converted tap switch, the instrument will automatically prompt, the new resistance value will be displayed soon, no need to restart.
4. Highly intelligent design, clever and advanced function setting, can automatically determine faults such as virtual connection and disconnection of the test line.
5, perfect protection function, can reliably protect the impact of the back-EMF on the instrument, with automatic discharge indication function.
6. It can display measuring current and measuring time.
7. Intelligent power management technology can effectively reduce the internal heating of the instrument.
8, can store 250 measurement data, power loss is not lost.
9, all Chinese menu and operating tips, intuitive and convenient.
10, built-in micro-printer, can print measurement results and memory records.
11, no power off calendar, clock function.
