MEWOI-ZC71 series programmable withstand voltage/insulation resistance tester
Description
Brief introduction
| ZC71 series program-controlled AC and DC withstand voltage/insulation testers are the company's safety products. The instrument uses linear amplification technology to produce a low-distortion sine wave output, making the test more accurate. The use of a 16×2 large-character LCD display screen and a user-friendly interactive operation mode make it clearer and easier for users to understand. The test results and test conditions are displayed at the same time, which makes users feel at ease about the test conclusions. The instrument can be widely used in fields that require safety testing. |
