Rosemount 3051S Series
Comprehensive Proof Test
The comprehensive proof test consists of performing the same steps as the
simple suggested proof test but with a two point calibration of the pressure
sensor in place of the reasonability check. This test will detect ~ 87% of
possible DU failures in the device.
Required tools: Field Communicator and pressure calibration equipment.
1. Bypass the safety function and take appropriate action to avoid a false
trip.
2. Perform Proof Test 1.
3. Perform a minimum two point sensor calibration check using the 4-20
mA range points as the calibration points.
4. Check the reference mA meter to verify the mA output corresponds to
the pressure input value.
5. If necessary, use “Choosing a Trim Procedure” on page 4-5 of the 3051S
Reference Manual.
6. Document the test results per your requirements.
7. Remove the bypass and otherwise restore normal operation.
8. Place the Security switch in the “ON” position.
NOTE
The user determines the proof test requirements for impulse piping.
