Sperry instruments 3021 Owner's manual

  • Hello! I'm your chat assistant, and I've just reviewed the user manual for the A.W. Sperry Insulation Tester, model 3021. This device offers four ranges for testing insulation resistance, along with continuity testing features. It also includes some useful functions such as auto-discharge, data memory and a backlight for easier work in dim conditions. I'm ready to answer any questions you might have about its operation or features.
  • What is the maximum voltage that can be measured?
    Does this tester have an auto-discharge function?
    How many data points can this device save?
    What happens if I exceed the pre-set insulation resistance value?
