Answer Posted / kaja farkhan
Calibration is nothing but comparisonof an unknown standard
with an known standard or in other words it is known as
checking the output is proportional to the input or not.
Loop checking is nothing but the instrument installed in
the field must give the signal to the control room without
any break. First in this the continuity of the cable will
be checked from inst to JB in field side and from the JB to
control room.
