The reading rate for continuity is fixed at 0.01 PLC.
Limits and digital outputs cannot be used when testing continuity with the conti-
nuity (CONT) function. If you need to use these operations, use the Ω 2 function
to test continuity.
When using the front panel inputs, the INPUTS switch must be in the "F" (out)
position. For switching modules, it must be in the "R" (in) position.
