True or False: You will need to personally calibrate the ohmmeter each time before testing resistance on a ground stud installation.

The statement is false because you do not need to personally calibrate the ohmmeter each time before testing resistance on a ground stud installation. Typically, ohmmeters are designed to maintain their calibration over a series of measurements unless they have been subjected to conditions that would cause them to go out of calibration, such as extreme temperatures, physical impacts, or electrical overload.

Most modern ohmmeters come with a self-test function or a reference standard that checks their accuracy before use, allowing the user to rely on the device without needing to recalibrate it for every single test. If the ohmmeter is functioning correctly and has not been damaged or misused, it should provide accurate readings without the need for frequent recalibration.

In professional practice, calibration of measuring instruments like ohmmeters is generally performed at regular intervals or when specific criteria indicate that recalibration is necessary, rather than on a case-by-case basis before each use. This streamlines the process and ensures efficiency in tasks such as grounding installations.
