POST ASSEMBLY TESTS 1. Conduct hydrostatic testing to 150% of maximum working pressure or
2,000 psi, whichever is greater.
2. Calibrate the transmitter per the calibration section of this manual.
3. Conduct nuclear cleaning to 1 ppm chloride content of transmitter
“wetted parts.”

Symptom Potential Source Corrective Action
High Output Primary Element Check for restrictions at primary element, improper installation or poor condition. Note any
changes in process fluid properties that may affect output.
Impulse Piping Check for leaks or blockage.
Ensure blocking locking valves are fully open.
Check for entrapped gas in liquid lines, or liquid in dry lines.
Ensure that density of fluid in impulse line is unchanged.
Check for sediment in transmitter process flanges.
Transmitter
Electronics
Make sure that post connectors and the sensor connections are clean. If the electronics are
still suspect, substitute new electronics.
Transmitter
Electronics Failure
Determine faulty circuit board by trying spare boards. Replace faulty circuit board.
Sensing Module See Sensing Module Checkout section. The sensing element is not field repairable and must
be replaced if found to be defective. See “Disassembly Procedure” for instructions on
disassembly. Check for obvious defects, such as a punctured isolating diaphragm or fill fluid
loss, and contact Rosemount Nuclear Instruments, Inc. at (952) 949-5210.
Power Supply Check the power supply output voltage at the transmitter.
