A restart of the display only will then occur.
License activation can be confirmed by observing that the PILD option is enabled using the
local display menu or host interface.
6.1 Recommendations for Transmitter Calibration
The ST 800 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 800 Series HART/DE Option User's Manual, document number 34-ST-25-38,
Section on "Calibration."
6.2.1 Dual/Triple Cal
STA, STD, STG and STF800 models are optionally offered with multiple calibrations. In lieu of a
standard factory calibration, units can be supplied with 1, 2, or 3 customer specified calibrations.
These calibrations are stored in the meter body and provide users with factory calibrated performance
at up to three different calibrated ranges. This increases application flexibility without requiring any
costly recalibration or additional inventory.
