Procedural Considerations
The details of procedures vary with device type. This section contains a set of procedures for Honeywell
HART Transmitters, and separate set of procedures for non-Honeywell HART devices.

Input Calibration

Input calibration of transmitters should be done only when necessary, and should be done only under
conditions that will ensure accuracy:
•
The transmitter should be taken out of service, and should be moved to an area with favorable
environmental conditions: clean, dry, and temperature-controlled.
•
The source for the input pressure must be very precise, and must be certified for correct operation.
•
The procedures should be done by qualified personnel.
For Honeywell HART devices, input calibration procedures are given in Table 12 through Table 14, and
for non-Honeywell HART devices, consult the manufacturer's User Manual..
