What is the purpose of a calibration label on an ohmmeter?

The calibration label on an ohmmeter serves the essential function of verifying accuracy and functionality. This label typically indicates that the instrument has been tested and adjusted to ensure that it provides precise measurements within a specified tolerance range. Regular calibration is critical for tools like ohmmeters, especially in aerospace applications where accuracy in measuring electrical resistance is crucial for safety and performance.

By having a calibration label, technicians can quickly ascertain that the tool meets industry standards and regulations, thereby ensuring reliable results when performing electrical checks and tests. This verification helps prevent errors that could lead to significant issues in assembly or maintenance in the aerospace field, where even minor inaccuracies can have severe implications.
