Revision 2 RMA803 Remote Indicator User's Guide 32
6.2 Remote Indicator calibration when connected in loop with DE
tansmitter
The user calibration of Remote Indicator can be performed as follows.
Setup details:
1. RMA801 device
2. STT700/STT250 DE device
3. DE Host (SCT3000/MCT404)
4. Reference DMM (optional)
Connect RMA801 device in series with STT700/250 DE device and connect DE host to the device.
Steps:
1. Keep device in DE analog mode
2. Connect SCT/MCT tool to the device and upload the devce database.
3. Verify STT device is in DE analog mode.
4. Now navigate to the “output calibration” Tab in SCT/MCT host and set output
percentage to 0%.
5. Verify that DMM is displaying loop current as 4 mA.
6. In Remote indicator navigate to the calibration menu “Cal Lo”in Standard Display
and press enter key to perform calibration. It will ask to “confirm” then press enter
key. Remote indicator will display “success” message then press menu key to exit.
After successful calibration, Remote indicator will show measured loop current
value on display.
7. Now set output percentage as 100% in SCT/MCT tool and wait for 30 sec to stable
the loop current.
8. Verify that Digital Multimeter (DMM) is displaying loop current as 20 mA
9. In Remote indicator navigate to the calibration menu “Cal Hi”in Standard Display
and press enter key to perform calibration. It will ask to “confirm” then press enter
key. Remote indicator will display “success” message then press menu key to exit.
After successful calibration, Remote indicator will show measured loop current
value on display.
Note: To update calibration parameetr into NVM (EEPROM), the “Cal Lo” and “Cal Hi” steps must be
done in sequence. If only Cal Lo is performed, then the Remote indicator will not strore the calibration
parameter into the NVM.
