Loop check activity is checking entire loop functionality, from field to DCS or Esd or plc or any logical system. It is necesary to check not only continuity of signal, but also range of calibration, alarms, set points and any signal included in the loop folder. For DCS will be tested with hart comunicator or temperature generator, 4-20mA, depends of witch instrument is involved. For Esd (emergency shut down system) loop check will be done with proper instrumentation tools to produce the specific presure or requaired level... For valves you must check all signals as open, close, hi and low limit switch, reset buttons, hand switches , feedback must be check and a lot of other things must be checked .. Loops are direct, revers, split range .. it is not easy and it is not only the continuity check to do.
