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.

Performance characteristics

  • 16×2 large character LCD display
  • Linear, low distortion sine wave output
  • 5 groups of program setting and memory function
  • Voltage ramp setting function
  • Unique arc detection function, defect identification is more accurate
  • ZC7110 has AC withstand voltage test function
  • ZC7120 has AC and DC withstand voltage test function
  • ZC7112 has AC withstand voltage/insulation test function
  • ZC7122 has AC and DC withstand voltage/insulation test function
