How do I get started using my new ECO?

ECO Bench Test

  1. Insert the host program CD into the host computer. Copy all files to a desired location on the host computer's hard drive.
  2. Plug the test cable's (optional equipment) DB-9 connector into the host computer's serial port.
  3. Connect a 9V battery to the test cable.
  4. Connect the instrument to the test cable.
  5. Start the program by double-clicking ECOView.exe (or the shortcut). The screen below will appear.

Dual analog ECO test cable

Click the yellow Select COM Port button. Select the COM port and baud rate (19200 is standard) for meter-to-PC communication. 

You can also select the COM port and baud rate from the pull-down menus in the lower left corner of ECOView.

Select the yellow Select Device File button, then choose the instrument-specific device file. The yellow button will disappear after the device file is loaded. 

You can also select Load Device File from the File pulldown menu at the top of the window.

Fluorometers only: Once the device file is loaded, an additional fluorometer setup tab will appear. Important: ECO fluorometers ship with two device files (See sample device files ). Loading the “standard” device file will provide data in counts. The other provides processed data in µg/l (chlorophyll) or ppb (phycoerythrin, CDOM, and uranine).

It's generally not necessary to change the other settings as they are factory-set. More on settings ...

The ECO will begin collecting data when power is supplied to the meter.

View Data

Select the Raw Data tab and Start Data if necessary, then the Raw Data tab to view data in the host program.

Put the fluorescent stick that ships with the meter (or the flat of your hand) directly in front of the sensor face. The signal value will increase toward saturation

  •  5 V analog
  •  +/- 16,000 for FL meters|
  •  +/- 4100 for all other ECOs

Select Plot Data tab. The X-axis represents sample counts and the Y-axis, data units. Click and drag to change the values on either axis. You can view either raw data or engineering units. Fluorometer measurements will be shown in raw counts if Raw Data is selected or µg/l (chlorophyll only) or ppb (parts per billion for all others if Engineering Units is selected.

If Engineering Units is selected, the backscatter calculation pull-down menu control will allow you to select one of the following for BB meters:

  •   Beta (117)—The total volume scattering
  •   Beta-Particle—The volume scattering of particles only
  •    bbp—Backscattering of particles
  •    bb—Total backscattering.

If Engineering Units is not selected, the backscatter calculation option is ignored and all BB data is plotted in raw counts.

Note: If you have loaded the device file for a fluorometer, the backscatter pull-down menu will not appear.

Refer to the ECOView user’s guide for details on selecting plot color and using the plot toolbar.

Press the Stop Data button to stop data collection and return the meter to "ready" status.

Retrieving and Uploading Data using ECOView

Save or Upload Data

Select ECO models have data logging capabilities with 1 Mb of memory, which is about 90,000 samples for single-parameter meters such as the FL and the BB. Mutliple-parameter meters such as the BB2F and custom Triplet can store about 65,000 samples.

You can simultaneously save both raw and processed data to the host PC.

IMPORTANT: Be sure to select a location to save data. Do NOT simply let the Windows operating system select the default location in Documents and Settings.The data will not actually be saved.
To save data to the host computer:
• select Record Raw (data in counts) and create a filename, and/or 
• select Record Engr (processed data) and a filename.

Select Start Data. The host computer will save time-synchronized .raw and .eng files, depending on the options you've chosen.

If you have an ECO meter capable of internally logging data (factory default is ON), you can transfer (upload) internally logged data to the host computer by selecting the Transfer Data tab, then Receive Data. Status indicators to the right of this button will display file upload progress.

To erase the internal memory in the ECO meter, select Erase Memory either under theTransfer Data tab or the Meter Setup tab.


Changing Meter Settings using ECOView

You may change configuration settings in ECOView according to your application.To change settings, the meter must be powered, but NOT actively sampling or in sleep mode. 

If the meter is collecting data: Select Stop Data to put the instrument in a communications-ready mode.

If the meter is in sleep mode: Supply power to meter; wait until it "wakes" and begins its data collection cycle. Click Stop Data to put the instrument in a communications-ready mode.

Click in the white input area in the Change Settings To column, and input the desired value. Click the associated  button to the left. The new value will appear under the Current Ram Settings column and be stored in the meter’s RAM (temporary) memory. The yellow Setup Not Stored warning will remain until you select Store to Flash.

Factory default: 1 Hz. 
(Single-channel meters: +/-55  •  Dual-channel meters: +/-28  •  Three-channel meters +/-12)
The number of data measurements taken that combine into each reported sample. Selectable from 1 to 65535. This setting determines the rate of output. The higher the number, the lower the sampling rate, which is displayed on the main window in the upper left corner and in the Meter Setup tab.

Factory default: 0.

This is the number of samples (a row of data) coming from the instrument. Selectable 0 to 65535. Selecting “0” will result in continuous operation.


 Factory default: 0.

The number of "groups" of samples the instrument will collect between low power (“sleep”) states. It is configurable from 0 to 65535. Selecting “0” will cause the meter to “cycle” continuously. Not applicable for RT meters.


Factory defaults: 000005 all ECOs except BB3 and BB9: 000010

The time interval between reported measurements in HHMMSS, with no colons. Set interval for a minimum of 5 seconds. DO NOT set to less. Not applicable for RT meters.

Factory default: Logging ON. 

Select ECO meters can log up to 1 mb of data (between 50,000 and 65,000 samples, depending on the model). Not applicable for RT meters.


If you set the number of samples to a low number (less than 5), the meter will sample the specified number of times, then may go into a sleep state depending on the settings. You will be unable to communicate with the meter. This is common for moored operations, where the meter may be set up to take a few samples every several hours. Between samples, the meter will be in a low power “sleep” state, during which time communication is disabled.

To “wake” the meter and re-establish communication:
Go to the Raw Data tab and turn off power to the instrument for a minute. 
Select Stop Data several times at approximately 2 times per second while applying power.

Not applicable for RT meters. 

Saving Changed Settings

When you are satisfied with the settings you have input, select Store to Flash to save your settings. The yellow warning banner should disappear.

If you do not want to save settings, the meter will use the settings shown under Current Ram Settings and the yellow warning Setup Not Stored will remain visible.

Example Settings
Set Avg/Data Rate = 55
Set Number of Samples = 60
Set Number of Cycles = 24
Set Time Interval = 010000
The instrument will collect 60 samples, approximately one second apart, once every hour for 24 hours. (See more examples)
