What to do if measured value is not correct on Peak Atlas LCR45?
- S

  If the measured value doesn't appear correct on your Peak LCR45 Measuring Instruments, ensure the probes are well-connected to the component under test for a few seconds, allowing the readings to stabilize. Verify that nothing else is connected to the component and avoid touching the connections during measurement. If the issue persists, the LCR45 may have selected a non-optimal mode; try a manual mode. Also, the component value may be outside the supported measurement range, or the component’s design frequency may not correspond to the test frequencies used by the LCR45.

Why does my Peak Measuring Instruments show that the calibration date is approaching or has passed?
- G
  Gerald FryeAug 3, 2025
  Your Peak LCR45 Measuring Instruments will continue to function normally even after the calibration due date has passed. The calibration date is simply a recommendation.

Why do measured values vary between readings on Peak Measuring Instruments?
- J
  jeffrey20Aug 9, 2025
  The displayed resolution on your Peak Measuring Instruments is intentionally set higher than the internal measurement resolution to minimize rounding errors. Therefore, variations within the specified measurement resolutions are normal.

How to fix resistance or inductance measurements not close to zero on Peak Atlas LCR45?
- A
  Adrienne WalshAug 15, 2025
  If the resistance and/or inductance measured on your Peak Measuring Instruments is not close to zero when the probes are short-circuited, perform a probe compensation.

What to do if capacitance measured is not near zero on Peak Atlas LCR45 Measuring Instruments?
- T
  Travis BoydAug 21, 2025
  If the capacitance measured on your Peak Measuring Instruments when the probes are open circuit is not close to zero (±1.0pF), perform a probe compensation.
