Calibration Worksheet for Submersible TransducersCalibration Worksheet for S: U.S. Geological Survey

Check that the well is unobstructed. If the well depth is not known, measure the total well depth. If necessary, install an instrument shelter that will protect the transducer and data logger from vandal¬ism and weather. Keep the transducer packaged in its original ship¬ping container until it is installed. Connect the transducer, data logger, power supply, and ancillary equipment. Record the model, serial number, and pressure range of the transducer in the field note¬book. Install the pressure transducer by lowering it into the well so that it is submerged below the water surface. Avoid dropping the transducer or permitting sharp contacts with the sides of the well casing. Do not allow the transducer to free fall into the well. The Calibration Worksheet for Submersible Transducers: U.S. Geological Survey mobile app allows you to replace your paper calibration worksheet with a mobile device. The mobile form includes fields to document items such as data processing number, site name, watch time, measuring device and measured water level. Once the mobile app is filled out a secure PDF is generated. The PDF is easy to share, and a copy is stored in your account for your well monitoring records. You can also use the App Builder to personalize and customize this mobile form.
