PD Analyzer

Feature:

1. large scale integrated circuit make the tester more stable and accurate..

2. large-screen CRT, the screen area to work effectively 100 × 80mm, can be clearly observed discharge waveform.

3. with A, B, C three-channel test interface, more convenient testing.

4. using double-header shows the amount of discharge, both figures table shows PC value, while another pointer header shows PC value, the pointer table can be divided into linear and logarithmic instructions.

5. Low noise, high detection sensitivity, wide capacitance coverage area

6. Small size and light weight make it easy to carry.
