FAQs
How often do I need to calibrate my gauge?
There is no fixed time, calibration frequency is based on how often the gauge is used and the conditions that the gauge is exposed to. Frequent use and abrasive materials will require more frequent calibration, low use in a clean environment will allow less frequent calibration. Usually the user determines the calibration frequency.
Can the Nogo gauge enter the part?
Generally no, but a limited entry is permissible in some cases, see download sheet for details.
