Friends, plz understand the question first. The
interviewers has mentioned "how to calibrate a NEW i/p
converter?"
Why the new i/p needs calibration?
Your answer must be like this..
"Sir, the new i/p would be factory calibrated with high
accuracy master instruments, so before we commission it in
the plant we have can check its output by applying proper
signal, unless we have good accuracy masters we no need to
disturb the calibration. If yes, we can do the calibration
using the 30psi regulated supply, 4-20 mA source, and
receiver gauge."
