Form Factor Note: "Make sure the top end is connected to the sensor end with the water level logger cable as described in Getting Started with the Logger. 2. Attach any small parts, such as bolts with nuts, before you go into the field so you don’t risk losing them in the field. 3. Lower the logger into the well or stilling well. 4. Use the Onset well cap if it is a 5 cm (2 inch) well. Otherwise, use a 1/4-inch bolt of sufficient length to span the well top or washer"
