功能描述

An overview of the instrument adopts advanced switching power supply and precision measurement technology, takes the high-speed microcontroller as the core by high speed A / D converter and programmable current source technology, achieves the measurement result is unprecedented and highly automated measuring function, has the advantages of high precision, the instrument adopts advanced switching power supply and precision measurement technology, takes the high-speed microcontroller as the core by high speed A / D converter and programmable current source technology, achieves the measurement result is unprecedented and highly automated measuring function, with high precision, wide measuring range, stable data, good repeatability, strong anti-interference ability, perfect protection function, fast charge and discharge rate characteristics. The instrument has the advantages of small volume, light weight, easy to carry is testing transformer, motor, transformer and so on inductive devices, DC resistance of a new generation of products, to replace the single, double bridge test is power supply unit, transformer manufacturing industry and large and medium-sized with electric transformer DC resistance measurement the ideal product.

儀器特點

1, using high-speed 16 bit A/D converter, measured data stability, good repeatability.

2, automatic test without range selection, automatic programmable current source technology, the current gear stepless can, by the internal micro controller according to the measured resistance automatic control, so as to achieve wide measurement range and the best measurement condition, manual switching current shifting.

3, strong anti-interference ability, perfect protection function, to avoid the reverse voltage to play a bad instrument, with automatic discharge sound indicator function, charge and discharge speed.

4, the test repeatability is good, the instrument internal procedures using anti pulse interference averaging filter method to filter the error data caused by instant interference.

5, fast response, the use of enhanced single chip processor, the speed is 12 times the ordinary microcontroller. 6, can display the measurement of current, resistance, and display the measuring time.

7, the instrument internal clock circuit, easy to record the test time and date.

8, can store 100 measurement data, and can delete, single print, all print, the test data is not lost.

9, the instrument is equipped with a panel type before changing paper high speed thermal printer, can be convenient to test the personnel on the spot to print the test data.

10, humanized Chinese character menu operation is simple, intuitive and convenient.

11, the instrument internal rechargeable battery, the scene without power supply can be tested, intelligent charging without damaging the battery.
