MEWOI-ZC2876/ZC2877/ZC2878 high frequency LCR digital bridge
Description
Brief introduction
The high-frequency precision bridge is a multi-function component tester for testing various electronic components. It uses the most popular 7-inch 800x480 color TFT LCD display, which enables users to read test results more intuitively and comfortably. It is an impedance measuring instrument with high speed, wide test range and 6-bit test resolution, which can meet the requirements of production line quality assurance, incoming inspection and laboratory measurement. |
