DH-21
Introduction 1-3
1.3 Checking the Model Number
Before installing your new “W ATER LOG”, check the information on the label of the sensor
enclosure. Check the model number, the range, and the output type to be sure that you have
received the instrument you ordered. The label will look similar to the following:
Model: DH-21
SN: 12345
Range: 0-15 psi
This example shows that the “W ATER LOG” Model DH-21 measures pressure within the range
from 0 to 15 psi. A similar label can be found on the battery compartment at the top end of the
vented cable.
1.4 Testing the System
Before installing the “W ATER LOG”, you may wish to test the system by connecting it to your
computer in the shop or lab. Testing the “W ATER LOG” in the shop or lab and observing its
readings will familiarize you with the instrument in an environment where it is easy to work and
you are near a telephone if questions should arise.
The “W ATER LOG” is shipped from the factory with the batteries disconnected. You will need to
connect the batteries before you can communicate with the “W ATER LOG” (see Section 2.3
“Accessing the Battery Pack and Desiccant”). You will also need to install the software on your
computer (see Section 3.1 or 4.1 for software installation instructions). After connecting the
batteries and the RS-232 cable, and installing the software, run WATERLOG.EXE from your
computer. You will be able to communicate directly with the sensor, set up parameters for
logging, set the time and date, etc. You should familiarize yourself with each of the features of
the software (see Chapters 3 and 4 for detailed explanations of each version of the software).
If you are unable to establish communication with the “W ATER LOG”, refer to Section 6.2,
Trouble Shooting. If you have exhausted all possibilities in the trouble shooting section, feel free
to call one of our support personnel at (435) 753-2212 for further assistance.
