Why can't I calibrate my Apera Instruments Test Equipment?
- JJared LopezAug 18, 2025
If your Apera Instruments Test Equipment won't calibrate, it could be due to several reasons. You might be pressing the button too soon; wait for a stable reading (the smiley face should stay on the screen). Ensure you're following the correct calibration order. The calibration solutions could be of poor quality, so use fresh, clean solutions from a reputable manufacturer. A dirty probe or clogged junction can also cause this; clean the probe thoroughly. An aged or dried-out probe may also be the culprit; soak it in Apera 3M KCL soaking solution for at least an hour. Make sure the probe is immersed at least 1 inch deep, and stir the solution to remove air bubbles. Finally, the probe might be broken; inspect it for damage and replace if necessary.
