  • Display Limitations: The MM600’s display, while large and equipped with an auto-ranging backlight, only offers a 4000 count. This count is standard in its price range but may not provide the reliability of slightly more expensive models, especially for those needing warnings for potential fatal shock hazards​.
  • Not a True-RMS Meter: It’s important to note that the Klein MM600 is not a True-RMS meter. This means it can only be used accurately for sine waves, limiting its utility in certain electrical measurements​.
  • Loose Test Leads Over Time: Users have reported that the test leads may start to feel loose in the meter jacks after some use. Although this does not impact the readings themselves, it might be a concern for those looking for a highly durable design​.
