TROUBLESHOOTING ST80/ST80L Flow Meter

7. On the FES-200, dial in a Delta R value with the thumbwheel from the column marked Delta R (ohms) on the Delta R data sheet. Compare to
the output value column (VDC Across 250 Ohms or mA Output as applicable) or the Indicated Display column or both. Verify that the meter
reading is within the stated tolerance of the flow transmitter. See examples 1, 2 and 3 at the end of this section, as applicable.
8. Repeat for each point on the Delta R table, except for the step value and zero value.
9. Turn power OFF and disconnect the FES-200 and DMM. Reconnect the sensor element connector.
10. Close the enclosure, making sure none of the wires are strained. Ensure any seals and gaskets are properly installed.
11. Restore power to the meter.
If you are troubleshooting the flow meter and the readings are good, the flow transmitter is good and the problem may involve the flow
element or interconnecting cable. If the readings are off, a flow element calibration may be required or the flow transmitter needs to be set
up. Contact FCI Customer Service.
