Calibration procedure:
calibration equipment: calibrator with handpump
For ex: Range of Transmitter is 0-100psi
Step1: connect the calibrator to the transmitter
Step2: connect the multimeter in series with transmitter to
verify the transmitter o/p in mA
step2: Apply the pressure to the transmitter by hand pump
in calibrator
Step3: compare whether both calibrator and the transmitter
showing the same value.if you applied 50 psi throuhg the
calibrator then the transmitter should have to show the
same value.If you find any error.Do the zero/span
Adjustment.by adjusting the zero/span screw
increasing/decreasing
step4: compare the transmitter and calibrator as per follows
calibrator Transmitter Transmitter o/p
in psi in psi in mA
0 0 4
25 25 8
50 50 12
75 75 16
100 100 20

If an instrument operates throughout it's full range
with linearity and porportionality when compared to
an NIST Standard, it is considered in calibration

Answer / sakthisithardhan
Calibration is the process of to set an instrument to show
the reading in between allowable scale....
example 0-10V meter
if ponter shows <0 means v've to calibrate it to show exact
0.

Answer / narenkumar1985
calibration equipment: calibrator with hand-pump
1: connect the calibrator to the transmitter
2: connect the multimeter in series with transmitter to
verify the transmitter o/p in mA
3: Apply the pressure to the transmitter by hand pump
in calibrator
4: compare whether both calibrator and the transmitter
showing the same value.if you applied X psi through the
calibrator then the transmitter should have to show the
same value.If you find any error.Do the zero/span
Adjustment.by adjusting the zero/span screw
increasing/decreasing
5: compare the transmitter and calibrator as per follows
with a desired range of an instrument with o/p 4-20mA

Answer / vivek saini
CALIBRATION of INSTRUMENT IS A TESTING OF ACTUAL VALUE ie:- value which is calculated WITH THE NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY (NSIT) VALUE GENERALLY DONE FOR CHECHING THE ACCURACY OF INSTRUMENT.

Answer / rafiq
calibration is nothing but the "testing" . it compares the
actual value to real value and realise that value takes the
decisions

Hi Frnds , If Suppose 1 Pair cable of 1.5 sq mm is used for Transmitter and instead of 1.5 sq mm if i used 0.5 sq mm cable will the resistance change will occur and does it affect our transmitter reading. plz mail ur answer to ntnkamble@gmail.com plz immediately mail ur reply
