Programs at the Hydrologic Instrumentation Facility
Training Course: Basic Electronics and Troubleshooting Instrumentation
Course Coordinator: Roy Johnson (rajohn) 800-382-0634 Ext. 81541
Description
This course covers basic electronic theory. In addition, specific items of study will include the electronics of direct current power systems, test equipment, grounding and lightning protection, troubleshooting data collection platforms, data loggers, RF troubleshooting, and soldering and de-soldering. Training will consist of classroom lectures and "hands-on" experience in troubleshooting and servicing electronic instrumentation sold by or rented from the HIF.
Target Audience
This is a basic course that will be of the most benefit to Water Science Center field personnel who are in the early stages of their career. The course should assist any employees who perform general hydrologic field work, and will be of particular value to those collecting continuous records at fixed-site stations. Attendance is limited to 18 students.
HIF training courses are specifically designed to benefit USGS hydrologic technicians and hydrologists who operate streamgages and other automated hydrologic monitoring stations. Non-USGS personnel who work for federal, state, tribal or local agencies whose job duties include hydrologic monitoring may attend HIF training classes on a space-available basis.
