Instrument maintenance

• Distinguish the fault into operational or functional types.

• Inventory• Physical damage• Interconnecting cables, Timer, Power supply

need to be checked periodically

Testing and Calibration

• Energy calibration test• Energy linearity test• Sensitivity test • Timer test

Quality ControlNo. Test Function of the equipment Reference Freq. of Routine

1. Scalar/timer and rate meter No Quarterly
