Test 1: Sonde Parameter ID Numbers
Select Flag 8 to view the sonde parameter locations. The list of _Loc_1 through _Loc_12 
(shown above) will exhibit values relevant to sensor identification.  When you click on Flag 8 
for the first time, all of the ‘_Loc_x’ display –INF. You will need to wait about 60 seconds to 
see the actual values.  
 
The string above (1, 7, 12, 14, 15, 96, 22, 18, 37, and 28) represents the sensor ID’s. These 
values provide the necessary information to the program so that each sonde parameter is known. 
For example, the Sonde Depth in meters PARA (parameter) at location 7 is sensor ID 22. In 
other words, Depth in meters is ID #22 and resides in memory location 7. See Appendix D for a 
complete list of sonde parameter ID numbers. This test has limited value, but can be useful in 
troubleshooting problems. 
NOTE: 
When you select a Flag the parameter value will not appear until the data logger clock 
moves past the ‘00 second’ mark. 
 
 
Test 2: Sonde RS-232 and SDI-12 Responses
 
This test should be executed to verify that communications from sonde to controller are fully 
functional. Refer to the Numeric Display below during this explanation. 
 
Set Flag 5 to read the sonde via the RS-232 communications port. The results to interpret 
appear in the far left two columns above. The _CntRS232 refers to the counter for RS-232 
readings. The counter increments about one time every second for 4 to 5 seconds. If the counter 
exceeds 5, then the sonde is not responding. The reading in the Display does not exceed the 
maximum of 6 counts.
