Section 2 —Optional Bench Check
2.1 Connecting Power and SCT/SFC
About the bench
check
The bench check is an optional procedure for checking your transmitter
before you install it by:
• Connecting a power source and an SFC (or a PC running SCT 3000
software) to the transmitter
• Running a communication test with an SFC (or SCT 3000)
• Checking the operation status and checking the configuration database
Also, if your transmitter was not configured at the factory, you can do so
during this procedure. See the Configuration section in the ST 3000 Smart
Transmitter, Release 300 and SFC Smart Field Communicator Model STS
103 User’s Manual 34-ST-25-14 for details.
When using the SCT 3000, configuration instructions and device
templates are provided on-line to aid in configuring your transmitter.
Factory Calibration
Each ST 3000 Transmitter is factory calibrated before shipment.
• First a full range calibration is performed.
• Next, a turndown calibration is done which is typically between 25% to
50% of its full range.
• Then it is calibrated to a range specified by your purchase order. This
means there is no need to calibrate the transmitter during installation.
(If no range is specified, the transmitter is calibrated to the turndown
factory default.)
• If you need any calibration information, see the appropriate section in
the ST 3000 Smart Transmitter, Release 300 and SFC Smart Field
Communicator Model STS 103 User’s Manual.
• If you have a transmitter with optional local zero and span adjustments,
you may just want to go to Appendix A for the local zero and span
adjustments procedure.
Procedure
Use the procedure in Table 1 to connect a power supply and an SFC
Model STS103 to your transmitter on a bench. See Figure 1 for reference.
