2. Perform partial proof test 1.
3. Verify the measurement for two temperature points for Sensor 1. Verify the
4. Perform reasonability check of the housing temperature.
5. Restore the loop to full operation.
6. Remove the bypass from the safety PLC or otherwise restore to normal operation.

Comprehensive proof test 3
The comprehensive proof test 3 includes a comprehensive proof test along with a simple
sensor proof test. Reference the FMEDA report for percent of possible DU failures in the
device.
Procedure
1. Bypass the safety PLC or take other appropriate action to avoid a false trip.
2. Perform simple proof test 1.
3. Connect calibrated sensor simulator in place of sensor 1.
4. Verify safety accuracy of 2 temperature points inputs to transmitter.
5. If sensor 2 is used, repeat
6. Restore sensor connections to transmitter.
7. Perform reasonability check of transmitter housing temperature.
8. Perform reasonability check on the sensor(s) values versus an independent estimate
9. Restore loop to full operation.
10. Remove the bypass from the safety PLC or otherwise restore to normal operation.
