Instrument Validation
Two simple tests offer complete “field-validation” of your Smart
mass flow meter. Each test consists of an easy to follow set of in-
structions shown on progressive screens that “walk” you through
the validation procedures.
The first test checks the system electronics, linearization and micro-
processor functionality and is performed by injecting a known input
value and confirming that the flow meter outputs the expected value.
The second test checks that the instrument’s primary sensing ele-
ments have not drifted or shifted from their original calibration. This
is accomplished by measuring the resistance of the velocity and tem-
perature sensors and comparing the results to the NIST-traceable
calibration data provided with the flow meter. Together, these tests
confirm that your meter is working correctly and that the calibration
variables did not drift, shift or change values.
System Requirements and Software Installation
Sierra's Smart Interface software is designed to run on your PC com-
patible computer with the following minimum system requirements:
• Windows 95/98; Pentium processor or better
• 8 MB of RAM; 14 MB of hard disk space
• RS-232 port (COM 1 or COM 2)
• display resolution of 800 x 600 (color screen recommended)
Windows™ 95/98 Software Installation
The Smart Interface software and its associated files are provided on
diskettes or CD ROM. The installation process is simple and mostly
automated.
1. Insert the SIP program disk in the drive. From the Windows Ex-
plorer select Run or double click the installer icon.
2. Follow the on-screen directions for software installation.
If needed, verify the following COM port settings in port properties:
Bits per Second = 9600
Data Bits = 8
Parity = None
Stop Bits = 1
Flow Control = None
In Advanced, make sure FIFO buffer is selected.
