6 Calibration

6.1 Recommendations for Transmitter Calibration

The ST 700 Pressure Transmitter does not require periodic calibration to maintain accuracy.
Typically, calibration of a process-connected Transmitter will degrade, rather than augment the
capability of a smart Transmitter. For this reason, it is recommended that a Transmitter be removed
from service before calibration. Moreover, calibration will be accomplished in a controlled,
laboratory-type environment, using certified precision equipment.

6.2 Calibration Procedures

For a Transmitter operating in analog mode, you must calibrate its output signal measurement range
using any compatible hand-held communicator or a local display.
One calibration option is to use the Honeywell Smart Field Communicator (SFC). Refer to the Smart
Field Communicator Operating Guide, 34-ST-11-14 for calibration procedures.
Calibration information and procedures for a Transmitter operating in the HART/DE mode are
provided in the ST 700 Series HART/DE Option User's Manual, document number 34-25-25-47,
Section on "Calibration."
