Not trying to be funny, but make sure the leads on your multimeter are in the correct place for measuring current.

Also, some multimeters will be able to power the instrument and simulate a loop, this can be interesting to ensure the instrument is good and not being brought down by the wire.

What PLC card are we talking about? I seem to remember that Siemens, for example, sent out their cards with a default to measure voltage instead of current. This caught a couple of people where I worked previously.
