Page 12: Operation
OPERATION The SAMBAT can be configured and read using the Winmemo II software via radio link, using a Data Pencil Radio, connected via USB to a computer. All command functions are available in the Winmemo II software. You can only communicate with the SAMBAT when it is out of the water. -
Page 13: Radio
Measurement rate: defines the interval between two GPS position readings. The interval is expressed in hours in increments of one hour. For a measurement rate of 6 hours, the SAMBAT will take a GPS reading every 6 hours. If the rate is set to 0, the GPS function is deactivated. -
Page 14: Sambat "Gprs" Tab
This parameter sets the immersion depth below which the SAMBAT will no longer attempt to transmit measurements or alarms by email. This setting should be left at 0 if the SAMBAT is mounted on a buoy (with the GPRS aerial always above water). -

Turning circle alarm: The turning circle alarm can be activated when the GPS function is active (the measurement rate setting is not 0). If the SAMBAT exceeds this turning circle (expressed in meters from its initial position), a GPS alarm will be generated. -
Page 17: Configuration Procedure For A Sambat Probe
CONFIGURATION PROCEDURE FOR A SAMBAT PROBE In this chapter, we will explain the procedure for correctly configuring the SAMBAT probe for several months of deployment. Connect the probe using Winmemo II and select EXPERT mode. Download the measurement files still present in the probe’s memory. - Page 18 Activate GPS mode and Brush operation in the SAMBAT / General tab. Enter the number of file transfers per day and check that the recipient email address is correct. Select whether or not to activate the various alarms. Select the button to confirm any modifications made to the configuration.
- Page 19 Open the Manage probe status window by clicking on the Status button. Click on the button to Start the probe After the memory has been erased, the probe switches to record mode. Close the window and disconnect the probe. Tel 02-97-36-41-31 Fax 02-97-36-55-17 http://www.nke.fr PAGE 19/43...

Page 20: Brush Function
BRUSH FUNCTION The brush function integrated in the SAMBAT probe is designed to reduce the presence of dirt and bio-fouling during prolonged deployments. By regularly using soft brushing, the SAMBAT brush keeps the sensor detection windows clean (optical window). It can be used on the turbidity, fluorescence, phycocianine and oxygen sensors. -
Page 21: The Brush: Start
On the next brush cycle, the brush will self-calibrate its position clockwise to recover its initial park position and possibly eliminate the obstacle that caused the blockage. If the blockage persists, the SAMBAT will continue to send alarm files. 6.2.1 The various types of alarms The SAMBAT generates two types of alarm on the brush. -
Page 22: Replacing The Brush
- Ensure the probe is Stopped. - Unscrew the screw using a no. 2 Allen key - Remove the worn brush - Install the new brush ensuring the flat part is facing outwards. Tel 02-97-36-41-31 Fax 02-97-36-55-17 http://www.nke.fr PAGE 22/43... -

100 meters in order to prevent inadvertent alarms. Above 100m, the setting resolution is the meter. For example, for a turning circle of 115m, any position of the SAMBAT buoy fitted with a GPS greater than 115m will generate an alarm. - Page 24 GPS aerial). GPS function performance is based on the reference position. An incorrect reference position may lead to false alarms. Ensure that the SAMBAT is correctly positioned at its final anchoring place before it is set to record. Tel 02-97-36-41-31 Fax 02-97-36-55-17 http://www.nke.fr...
