What to do if Apera Instruments Test Equipment calibration is successful, but reading is not accurate?
- TTerry BentleySep 13, 2025
If your Apera Instruments Test Equipment calibrates successfully but the reading remains inaccurate, consider these possibilities: the probe may be aged and needs replacement. Air bubbles around the sensor can interfere with readings, so stir the solution to remove them. A clogged junction can also cause inaccuracies; clean the probe and soak it in 3M KCL soaking solution overnight. When comparing with other testers, calibrate all testers using the same standards and test a third point to determine the most accurate one.
