APPLICATION NOTE NO. 72 Revised March 2008
Setting Up WET Labs ECO-FL Fluorometer with Bio-Wiper™
This application note applies to the following models of the WET Labs ECO-FL Fluorometer with Bio-Wiper:
• ECO-FLNTUS chlorophyll and turbidity sensor
• ECO-FLS chlorophyll sensor
• ECO-FLCDS CDOM sensor
These sensors can be configured to operate in Profiling or Moored mode:
• Profiling mode – The ECO-FL opens the bio-wiper when power is applied and keeps it open continuously, even when
power is removed. The ECO-FL samples continuously when powered, and outputs a voltage that changes as the
data changes.
• Moored mode – The ECO-FL opens the bio-wiper when power is applied, takes a sample, outputs a voltage, closes the
bio-wiper, and holds the voltage until power is removed.
When Sea-Bird integrates the ECO-FL with one of our CTDs, we set up the ECO-FL to operate in the mode appropriate for
the CTD. However, you may want to change the mode in the future, if:
• You purchased the ECO-FL for use with an SBE 19plus or 19plus V2, which can be field configured to operate in either
profiling or moored mode.
• You wish to use the ECO-FL in the future with another CTD; for example, you purchased the ECO-FL for use with an
SBE 25 profiling CTD and now want to use it with an SBE 16plus V2 moored CTD.
Changing the ECO-FL Setup
To change the ECO-FL configuration, connect the ECO-FL directly to the computer and to a 12 V power source, using
the cable supplied by WET Labs. Configure the ECO-FL using a terminal program (WET Labs provides a graphical
interface program, ECOView, which can be used instead of a terminal program – see www.wetlabs.com).
The required comm port settings are: 19200 baud, 8 data bits, no parity.
Configure ECO-FL for Profiling Mode Configure ECO-FL for Moored Mode
Send the following commands:
!!!!!
$set 0
$pkt 0
$sto
Send the following commands:
!!!!!
$set 1
$pkt 1
$sto
Notes:
1. Five exclamation points (!!!!!) accesses the ECO-FL command set.
2. For the $set and $pkt commands, the space between the command and the number is important. For example, make
sure that there is a space between $set and 0.
3. The $sto command stores the settings in memory. If you omit this line, the sensor defaults to its last stored settings.
After you have configured the ECO-FL for your CTD, reconnect the ECO-FL to the CTD.
