The main functions and features:

1, Three measuring loop synchronous measurement, display and automatic computing imbalance rate at the same time.
2, Functional configuration is highly flexible, three-phase, two-phase, single-phase measurement, the output current can be arbitrary combination, in regard to the tester 3 *10A type, can be combined into 10A + 10A + 10A way, 10A + 10A way, 20A way, 10A way, is extremely easy to use
3,Automatic programmable current source technology, previously mentioned various current combinations, are from the minimum value of 0 starts, a total of 1000 current gear, either manually select the typical output current, or by the internal micro controller automatically controls the output current, so as to achieve a relatively wide range and thebestmeasurementcondition.  
4, The measuring speed is quick, for on-load voltage regulating transformer high voltage side of star can not star power, need not fall line, a power can finish all take-off point three phase resistance value. Low pressure side can use 20A high current mode, can shorten the measurement time, and improve work efficiency.

5, Can be equipped with magnetic box, for large transformers, using magnetic survey to help, can greatly shorten the measurement time.
6, Highly intelligent design, function setting has advanced, can automatically judge the test line failure of virtual connection and disconnection.
7, Perfect protection function, can be reliably protected the back EMF shock to the instrument, with functions of automatic discharge instructions.                        
8, Can be stored (75 times) or print all measurement results, the instrument was built-in do not power-fail memory, can be stored for a long time measurement data and can print and refer at any time.

The main technical indicators:

1, Resistance measurement range: 100 μ ω ~20 ω

2, Resolution: 1 μ ω

3, Resistance measurement accuracy: plus or minus 2 0.2%

4, Current source output range: 3x (0~10A)

5, Volume: 420*260*210mm

6, Weight: 13kg
