Calibration range at which the
instrument calibrated
instrument range:maximum range of
instrument at which we can calibrate
instrument for example if we have a
pressure tx instrument range 0~10bar
we can calibrate it at any position
between 0~10bar suppose we calibrate
it at 0~4bar its mean its calibration range
is
0~4bar and instrument range 0~10bar

Answer / raja

CAlibration range is the range upto which we have marked
readings on a guage ( for e.g) .
Instrument range is the range upto which instrument can
detect measurand .

calibration range is always less than Instrument range.

Dead zone and hysteresis may take position between the
difference in instrument and calibration ranges
