Application Example: Deviation Limit for Pass/Fail Testing
A deviation limit (50 mohm in this example) is set up
around both sides of a setpoint. The relay closes (or
opens) when the reading falls within the deviation band,
and opens (or closes) when the reading falls outside of
this band. This mode sets up a passband around the
setpoint and can be used for contact resistance testing.
