1.2 Checking the Model Number
Before installing your new W ATER LOG ® H-310, 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: H-310
Range: 0-15 psi
Output: SDI-12
Input:
9.6 to 16.0 volts
S/N: 12345
This example shows that the W ATER LOG ® H-310-15 measures pressure within the range from
zero to 15 psi. This model works with a recording device that follows the SDI-12 protocol.
The full order number tells other details about the H-310. The key to the H-310 ordering system
is in Appendix B.
1.3 Testing the System
Before placing the H-310 in your selected location, you may wish to test the system by hooking
up the H-310 with your data recorder in the shop or lab, (as explained in this manual). Testing
the W
ATER LOG ® H-310 in the shop or lab in a bucket of water, and observing the data recorder's
readings is good. This familiarizes the user with the H-310 and the data logger in a clear, easy to
work in, environment. You are also close to the telephone if questions should arise. However,
for this test to work correctly, you must run a wire from inside the bucket that comes in
contact with the water back to the chassis ground of the data recorder. This will insure
that there is a good earth ground connection. The purpose for this ground connection is to
remove AC coupled noise from the bucket.
