Introduction 1-3

1.3 Testing the System
Before installing the H-3531 FlashLite™, you may wish to test the system by connecting it to your
data recorder in the shop or lab (See section 2.4 Connecting the Data Recorder). Testing the H-
3531 FlashLite™ in the shop or lab and observing the data recorder's 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 H-3531 FlashLite™ is shipped from the factory with the SDI-12 address set to zero. You will
be able to issue SDI-12 commands using "0" as the address after connecting it to your data
recorder. From the "talk" or "transparent" mode of your data recorder or using an optional H-
4191 (RS-232 to SDI-12 interface) with a terminal emulator like Hyper Terminal or Procom etc..,
issue an identify command ("0I!") to verify communication and then a measure command ("0M!")
to verify proper measurement operation. When the measurement is complete, the transducer will
return a service request which is simply its SDI-12 address. Your support software may not echo
the service request to the screen. If not, just wait the allotted amount of time for the measurement
to complete (See section 5.1 for interpretation of the SDI-12 response to a measure command).
When the measurement has completed, issue a retrieve data command ("0D0!"). This should
return your data values.

If you are unable to establish communication with the H-3531 FlashLite™, refer to section 3.3
Trouble Shooting. When you have exhausted all possibilities in the trouble shooting section, feel
free to call one of our support personnel at (435) 753-2212 for assistance.
