9.3 Periodic Testing / Calibration of Field Devices
Periodic testing and calibrating of the TS4000 should be performed according to the schedules
and procedures outlined in the TS4000 Instruction Manual. Testing and calibration procedures
should include, but are not limited to the following:
•
Verifying zero reading
•
Verifying application of a known concentration of gas
When testing produces results outside of General Monitors’ specifications, re-calibration or
repair / replacement of the suspect device(s) should be performed. Calibration intervals should
be independently established through a documented procedure, including a calibration log
maintained by plant personnel or third party testing service.
9.4 Periodic System Verification
The following system verifications should be performed at least annually:
•
Verify wiring, terminal connections, and stability of mounting for all integral safety
equipment including, but not limited to the following:
•
Power supplies
•
Control modules
•
Field detection devices
•
Signaling and indicating devices
•
Accessories connected to field and signaling devices
•
Verify proper safety system operation by performing a full, functional test of all
component devices – ensuring appropriate levels for all Alarm and Warning conditions
•
Verify fault / malfunction circuit operation
