19 LISST-200X Introduction & Quick Start
After the sampling program is started, you will see the status bar
change to ‘Sample Program Running’ as shown below. At this point
the instrument is running and ready for deployment.
Note that even when the sampling program is running, sampling will
not necessarily start immediately. For example, if you have selected
the mechanical switch as the start condition, the instrument will only
react to the swtich after the sampling program has been started. Only
then will actual sampling begin. If you want sampling to begin
immediately, select a start condition of “Delay” with zero as the delay
time.
While waiting for the start condition the LED on the connector endcap
will double blink every few seconds to alert the user that the instrument
is running but not yet sampling. During sampling the LED will
illuminate during the actual measurement of an averaged sample. For
example, if the sampling is set for 1 Hz sampling with measurements
per average set to 20 then the LED will blink once per second. If
settings are set for a 30 second average every 15 minutes then the
LED will illuminate for 30 seconds every 15 minutes.
Step 17:
Collecting Data
For our example we can move the white lever on the endcap to the “1“
position. Sampling will start. Data collection will continue until the Stop
Conditions are met. In our case, until the switch lever is returned to the
“0” position.
If the Start and Stop Conditions are set to Depth, External Mechanical
Switch, or External Digital Input the program will return to checking for
the Start Condition. This will only be true if the Start and Stop
conditions match. For example, Depth Start and Depth Stop. For non-
matching Start and Stop Conditions, such as fixed number of samples
or Time Stop, the program will terminate and the instrument will go into
a low power sleep mode.
To stop a running program, or wake it from low power sleep mode, use
the
‘Stop / Wake Instrument’ button from the status bar.
Note that the above options will only be available if you started the
sample program from the software. If you plug in an instrument that is
already executing a sampling program, you will need to manually wake
the instrument by selecting the ‘Wake Instrument…’ button and
selecting the COM port the instrument is connected to.
