3.1 Installation Site Evaluation
Evaluate the site selected for the ST 800 Transmitter installation with respect to the process system
design specifications and Honeywell’s published performance characteristics for your particular
model. Some parameters that you may want to include in your site evaluation are:
Environmental Conditions:
o Ambient Temperature
o Relative Humidity
Potential Noise Sources:
o Radio Frequency Interference (RFI)
o Electromagnetic Interference (EMI)
Vibration Sources
o Pumps
o Motorized System Devices (e.g., pumps)
o Valve Cavitation
Process Parameters
o Temperature
o Maximum Pressure Rating
3.2 Honeywell MC Toolkit
In preparation for post-installation processes, refer to the MC Tookit User Manual, Document # 34-
ST-25-20, for battery conditioning and device operation and maintenance information.
3.3 Display Installation Precautions
Temperature extremes can affect display quality. The display can become unreadable at temperature
extremes; however, this is only a temporary condition. The display will again be readable when
temperatures return to within operable limits.
The display update rate may increase at cold temperature extremes, but as with readability, normal
updating resumes when temperatures are within limits for full operability.
