what are the documentation and instrument identification system used to identify the correct device to be calibrated? name atleast three.
Answer Posted / carl_ellis
- P&ID: tag name/number for the instrument in question,
but not the location
- Loop diagram shows tag name/number, has a location
description (field, panel, I/O rack, control room) and
wiring terminals ID (are wires 1578 and 1579 connected to
the instrument in question?)
- ISA's instrument spec sheet has a section for calibration
with input/output, but more importantly, the following
section has Component Identification by manufacturer and
model number. The serial number isn't there because this
document defines the functionality, not a specific device.
- The company's "Instrument Specification Data Form" should
have a field for a location and instrument serial number
- Calibration data sheet should have a field
for "Location", tag and serial number.
- There should be a stainless tag on a field instrument
- The handheld communicator displays the tag name when
connected. The instrument's tag name should match the work
order's tag.
- The local "Calibration status label" on or inside the
instrument always has a tag ID.
