Answer / rizwan afzal

Dear
change in pressure can be +2.5kpa/s or -2.5kpa/s. while
sample rate is 0.5 sample per sec and range is 0 to 1500Kpa
so error is

e=0.5s*2.5kpa/s
e=1.25kpa
now to calculate percentage of error

%e=(100*1.25Kpa)/1500kpa
%e= 0.0833%
keep in mind error can be +0.0833% and -0.0833%
