2.1Connecting 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 |
| When using the SCT 3000, configuration instructions and device |
| templates are provided |
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. |
