does not use the orange and black wires and the ends of each of these wires
should be taped to prevent shorting.

The datalogger must be properly grounded. This reduces
electromagnetic noise and chances of damage from lightning.
NOTE
5. Programming
Use Short Cut, CRBasic, Edlog, or the datalogger Keyboard/Display to
program the datalogger to read these sensors. All programming methods
require the sensitivity value which is listed in the calibration certificate. A
calibration certificate should accompany every sensor received from Druck. It
is specific to the individual sensor; verify that the certificate and the sensor
have the same serial number, and retain the certificate for your records.
5.1 Using Short Cut
Short Cut is the easiest and typically the preferred method for programming the
datalogger. Short Cut will ask for the sensitivity which is listed on the
calibration certificate. From this value, Short Cut will calculate the multiplier.
Choose either the “Manual Offset” or “Automatic Offset” module to adjust the
transducer reading to the current water level reading.
Short Cut stores the Druck level data in the high resolution format. Short Cut
also generates a wiring diagram that shows how to connect the Druck
transducer to your datalogger.
