Procedure for field calibration of Honeywell compound characterized SmartLine Wireless
Transmitters
This procedure applies to the following Honeywell SmartLine Wireless Transmitters
Honeywell SmartLine Wireless Transmitters are fully characterized at the factory and have an
applied factory calibration over the range of the transmitter (URL). Field calibration is provided
to allow up to 5% adjustment over a reduced operating range providing accuracy within .075% of
the reduce range or ±0.025 + 0.05 20 psi span psi or ±0.025 + 0.05 (1.4 bar) span bar in % span.
Compound characterized pressure transmitters allow calibration at both positive and negative
relative pressure calibration points within the characterized range of the transmitters meter body.

Upper and Lower Calibration:
The SmartLine Wireless Transmitters provide calibration for upper and lower calibration points
as well as the option for calibration of zero. The zero calibration is independent of the upper and
lower calibration and is applied as a bias whereas upper and lower calibration adjusts the gain
and offset of the characterization. Zero calibration is available from the local interface at the
transmitter and is done with the device mounted in its operating orientation and applied "zero"
offset head pressure.
Upper and lower calibration are only available when connected to the network where access to
the upper and lower calibration points as well as access to the calibration command is available.
Upper and lower calibration requires the values for the upper and lower calibration points to be
entered and the status of the calibration operation to be verified.
