tension on the cable if you perform this test without actually submersing the sonde. To turn the
motor off, click on Port 6 again to turn it OFF (no green light).
Set Port 5 ON to reverse the direction of the Winch motor. You should turn Port 6 OFF (stop
motor) then set Port 5 ON. Turn Port 6 ON again. You should observe the Winch reel in cable.
Again help put some tension on the cable with your hands if you perform this test without
actually submersing a sonde in water. Click Port 6 again to turn the motor OFF. The green light
should not be visible at Port 6 at this time.
Quick Guide to Sonde Movements
To move sonde down:
Verify that Port 5 is OFF
Turn Port 6 ON
To stop sonde motion (up or down):
Turn Port 6 OFF
To move sonde up:
Turn Port 5 ON
Turn Port 6 ON
In summary, all of the tests above must produce data and/or motor movements. Verify that the
data is reasonable as explained in each section. Verify that each command results in a certain
number of attempts before it ‘gives up’. For example if you see the SDI-12 counter exceed 18
this could mean that the DO warm-up time is set extremely long, or it could mean the sonde is
not responding to an SDI-12 command. A 60 second DO warm up time typically produces a
count of 18 or so, but may read higher if optical probe wipers are set to wipe each interval. A
second example, the Depth Finder obviously will vary with depth. Shallow water may result in
2 to 3 attempts, while deeper waters could mean 10 to 15 attempts. When you interpret counter
readings, consider your test conditions.
OTHER PRE-DEPLOYMENT TESTS
The tests you performed above provide valuable information related to functionality of your
system components and communication between these components. You may perform
additional tests that may be valuable. Some of these are for subsystems that are optional on your
YSI Profiler. For example, you may have meteorological sensors that you would like to confirm
working.
Refer to the tables below to understand what the Ports and Flags control. The tables differ
slightly depending on whether you are working in Setup Mode (Flag 2 ON) or Profiling
(Operational) Mode (Flag 2 OFF).
Many of the tests described above have explained the function of these ports and flags. The
tables below should help you further explore testing of interest. In addition use the Status
Monitor (shown below) to monitor system operation. Keep in mind that when the collection
schedule is enabled it has precedence over the Connect Screen.
