Fault-finding guide

No preamplifier output at working bias high count rate LED flashes 

Source activity too high resistive feedback preamplifier blocked 

Preainthfier failure (FET blown bias voltage short circuit) 

Check amplifier output with oscilloscope to confirm

Reference deconvolution is unusual among data processing methods in using internal evidence to repair the damage done to the spectral data by instrumental imperfections parenthetically, it may be noted that the form of the correction function R t) itself can be a useful guide to instrumental fault-finding. The principal uses of reference deconvolution are in the pro-... 

Parr, E. A. 2006. Hydraulics and Pneumatics A Technician s and Engineer s Guide, 3rd ed. Oxford, U.K./Boston Butterworth-Heinemann. A relatively brief overview of hydraulics and pneumatics. Covered are hydraulic pumps and pressure regulation, air pressure, treatment and regulation, control valves of various types, actuators, hydraulic and pneumatics accessories, process control pneumatics, and safety, fault-finding, and maintenance. 

This step is completed by trained observers who are, in most cases, fellow workers. These observers are not intent upon finding fault or blaming workers for their safety behaviors, but to document the rate at which workers perform tasks in a safe manner or in an at-risk fashion. The observations usually take 10 to 15 minutes. The data sheets developed by the steering committee should be the guide and specify the expected behaviors. These observations are strictly conducted under the conditions that no names are used and no blame is placed. These observations are best when peer-to-peer observations are performed and feedback can be given immediately. Observation data is entered into a database for analysis and problem solving. This approach builds a sense of ownership in this type of safety program.
