When using an ohmmeter between terminals 95 and 96, what reading is expected?

Explanation:
When measuring the resistance between terminals 95 and 96 using an ohmmeter, the expected reading of 0 to 0.2 Ω indicates that these terminals are effectively shorted or have very low resistance. This low resistance reading suggests that these terminals either belong to a component that is functioning properly with minimal resistive loss, or they are part of an electrical circuit where minimal resistance is desired to ensure efficient current flow. In many electrical devices, especially those involving relays or contactors, a reading in this range is typical, as it confirms that there is a conductive path with little to no obstruction. A reading within this range could imply that the device is operational, as high resistance may indicate an open circuit or a malfunctioning component. In contrast, readings like OL (or ∞), which indicate infinite resistance, would suggest an open circuit or a broken connection, which is not expected between these terminals if they are meant to be in a closed circuit. Similarly, readings of 1.8 to 4 K Ω or 40 to 400 Ω would not be appropriate for terminals that are designed to be low-resistance; such readings could indicate issues such as corrosion or damage in the connections if they are not meeting the expected low resistance
