As the previous section showed, achieving the best performance from load cells requires attention to connectors. This is particularly true with connectors made of nylon (listed as polyamide, PA66, etc.). Nylon is frequently used in low cost connectors because it is cheap and flexible. However, nylon easily absorbs moisture so humidity can easily lower the insulation resistance. Special attention is required when nylon connectors are used in humid environments and areas where condensation can occur. A fall in the insulation resistance of connectors may cause drift* in the indicator values. If unexplained drift occurs, consider the resistance of the connector.

A&D’s connector-type weighing indicators are equipped with high quality metal connectors as standard. *Drift: A condition in which the indicator value does not stabilize and gradually shifts or changes sporadically.
