Main performance features

Acquisition and control using high-speed, highly integrated microprocessor.
Communication USB interface used between a laptop and instrument.
The communication between the laptop and the instrument can use wireless Bluetooth interface or wireless WIFI interface (optional)
The wireless WIFI interface can be conveniently used on tablet computers and smart phones.
Hardware adopts dedicated DDS digital high-speed scanning technology (USA), which can accurately diagnose the faults like winding distorted, bulged, shift, tilt, inter-turn short-circuit deformation and inter-phase contact short-circuit.
High-speed dual-channel 16-bit A/D sampling (in field test, move tap changer, and the wave curve shows obvious change) .
The signal output amplitude is adjusted by software, the maximum amplitude peak value is ±10V.
The computer will automatically analyze the test results and generate electronic documents (Word)
The instrument has dual measurement features: linear frequency scanning measurement and segment frequency scanning measurement, compatible with measurement mode of two technical groups in China
The amplitude-frequency characteristics are in line with the national technical specifications on amplitude-frequency characteristics tester. X-coordinate (frequency) has linear indexing and logarithmic indexing, so you can print out the curve with linear indexing and logarithmic indexing. The user can choose either according to actual needs.
Automatic test data analysis system,
