What to do if measured value doesn’t appear to be correct on Peak Measuring Instruments?
- K
  Kathryn CooperJul 28, 2025
  If the measured value on your Peak Measuring Instruments doesn't seem right, ensure the probes are securely connected to the component throughout the test. Also, verify that the component under test isn't connected to anything else and that you're not touching the connections. The component value might be outside the measurable range, or its design frequency may not match the test frequencies of the Atlas LCR.
