CableEye Tester Calibration Verification Board | Cable & Harness Tester

Populated with precision resistors, it allows users to determine empirically whether the tester requires calibration. The CB50 may be used on all CableEye models. The CB50 is intended for periodic verification of tester calibration. To ensure that resistance measurements remain accurate, CAMI recommends yearly calibration. However, depending on environmental conditions and usage, testers may need calibrating more or less frequently. Certain components within models M3U, M3UH, HVX, and HVX-21 (i.e. those capable of measuring resistance) are analog components whose characteristics change slightly over time. This aging is a natural phenomenon common to all electronic components and may cause resistance measurements or gradually deviate from normal. A tester that is out of calibration will give inaccurate results. Some (maybe all) resistance measurements will be incorrect. Consequently, it may Pass what should Fail and, conversely, Fail what should Pass. In other words product yield will be contaminated due to unreliable quality.
