Answer / naren
connect to pressure calibator, apply the low pressure -60
adjust the span into low pressure and then apply the high
pressure then adjust the span screw into high value. it is
calibrated in the range of -60 to -20.
if it is the SMART transmitter its easy, just apply URV and
LRV value through Communicator then connect to the pressure
calibator then check URV, LRV and intermediate value

Answer / ramesh
we can apply the +ve pressure to the lp side that is 60
with zero, then +ve 20 with span with respect hp open to
atmosphere
or apply -ve pressure that is vaccum to the hp side with
respect lp open to atmosphere

Answer / welcome4ujd
make the calibration set up , to get -60 , give 60 in lp
sidethen adjust zero screw, give 20 in lp side toget -20
url , and adjust span screw.

Answer / sn
apply -60 to the transmitter n make the o/p as 3 psi, then
giv -20 as the input n adjust the o/p as 15 psi.

Answer / sandeep patel
connect transmitter in bench setup, left LP side of transmitter open to atmosphere and apply -60 mmwc to HP side and check it s o/p is 4 mA or not and if it is not, then do zero trimming. then apply -20 mmwc to HP side and check o/p is 20 mA or not otherwise fo span trimming.

Urv-LRV÷4=Span
-60=4ma
-50=8ma
-40=12ma
-30=16ma
-20=20ma

Answer / anup ramteke
It depends upon the type of transmitter u are having. If its
HART based transmitter then either u can calibrate it
through HART calibrator. firstly go to basic set-up mode and
feed the URV as well as LRV values. And if u want to
calibrate it at field itself when HART calibrator is not
available then u can set LRV value by entering its value in
mode 2 whereas for URV its mode 3.

Answer / suvendu sekhar giri
You can give positive pressure on low pr side keeping the
high side open to atomosphere for lrv (-60) & urv (-20)or
you can give negative pressure on high pr side for lrv(-60)
& urv(-20) keeping low side open to atomosphere.You can
adjust zero at lrv & span at urv. If it is smart
transmitter then you can zero trimming keeping both the low
& high pressure side open to atmosphere.

Answer / venkat
actually we can calibrate LP side by positive pressure and
Hp side also we can calibrate by negative pressure but LP
side better
