Table 14 Input Calibration (DE Transmitters) –
Correct Input (Zero), LRV, URV; Reset Corrects
Input Calibration (DE Transmitters) - Correct Input (Zero), LRV, URV; Reset Corrects
Requirements:
 Input source, with accuracy of at least
0.04%
 resistor, at least 250-ohms
 Voltmeter or Ammeter
 24 Vdc Power Supply (nominal)
 Clean work area with suitable
environmental conditions.
 Pressure Transmitter must be level.
Overview of Procedures:
The Zero-Correct procedure establishes the
correct vertical positioning of the response
profile.
The LRV Correct and URV Correct
procedures establish the correct slope of
the response profile in the process operating
range by rotating the response profile
around the zero-reference point as a pivot.
The Zero-Correct procedure can be done at
any time during the Correct LRV and Correct
URV procedures in the same calibration
session.
The Correct LRV and Correct URV
procedure should never be performed
without first performing the Correct Input
(Zero) procedure in the same calibration
session.
Objective(s):
Using a precision PV input source as a reference, command
the transmitter to write calibration coefficients to Non-
Volatile Memory associated with transmitter input hardware
and software.
 Correct Input (Zero)
 Correct LRV
 Correct URV
