Next, the configuration for the type of gauge being read must be specified. See Section
4.8, “Gauge Settings”.
Assume a Geokon Model 4500S-50 Vibrating Wire Pressure Transducer with a gauge factor of
0.01234 psi/digit (found on the calibration report). Multiply this value by 2.31 to convert psi to
feet of water, resulting in a factor of 0.02851. As with all vibrating wire gauge measurements, a
zero reading needs to be determined for proper operation. Enter the gauge type and clear the zero
reading, gauge factor, and offset positions in the datalogger’s memory using the G command.
