  • Page 4 Safety Information BURSTING HAZARD Should water enter the Cyclops-7 Logger and come into contact with the enclosed batteries, then the batteries may generate gas causing the internal pressure to increase. This gas will likely exit via the same location where the water entered, but not necessarily.

    At the end of the deployment period you need only to open the logger and connect it to a host device via USB. The Cyclops-7 Logger will appear as a ‘thumb drive’. Your temperature and sensor measurements, together with a time stamp indicating the time the measurement was made, are recorded in text files in the folder having the serial number of your Cyclops-7 Logger.

    10 minutes (or at some other interval you may have set using Cyc7Control). 5) Inspect the o-ring seal for debris. 6) Close the Cyclops-7 Logger by screwing the white housing back onto the black end cap. 7) Deploy the Cyclops-7 Logger.

    Time – All Cyclops-7 Logger times are UTC (formerly known as Greenwich mean time (GMT)). The Cyclops-7 Logger internal clock will drift in the < 10 ppm range (<about 30 secnds/month) so you should plan to connect it occasionally to a host having an internet connection.
  • Page 9 Always use the paper tube supplied with the Cyclops-7 to contain the batteries. Use only new batteries as replacements. Coin Cell Battery Life – The Cyclops-7 Logger uses a coin cell for backup of the clock when the power is switched off. This coin cell will supply roughly 2 years of clock operation, but this is only required if the main power is off.
  • Page 10 Flashing Red Contact PME. AutoRanging – The Cyclops-7 sensor has three output ranges: 1X, 10X and 100X. The best of these ranges is automatically selected by the logger based on the voltage measured of the sensor. The logger software remembers the best range and, at each sample time, first measures sensor output voltage using this range.
  • Page 11 100.1X but the calculations would use 100X. Closing and Opening – Close and open Cyclops-7 Logger like you would a flashlight: open by unscrewing the white cylinder from the black end cap. Close by screwing the white cylinder on.
  • Page 12 Upload Files to an Android device – It is possible to transfer your measurement files from your logger to an android device. This operation has 3 prerequisites. 1. An Android device equipped with USB On-The-Go (OTG). OTG is a feature on most modern Android devices that allows them to act as a USB host.

     Manual.pdf this manual. These files are located on the root directory of the Cyclops-7 Logger. PME suggests you leave these programs where they are on the Logger, but you may copy them to any folder on your computer’s hard drive.
  • Page 14 Begin program operation by clicking on Cyc7Control.jar. Software presents the screen shown below: The Cyclops-7 Logger must be connected to USB at this time. When correctly connected the Logger will display a constant green light. Precision Measurement Engineering, Inc. (760) 727-0300...
  • Page 15 The field of view available to these sensors is quite important in establishing their response. PME’s Cyclops 7 Logger is supplied with a sensor cover that not only protects the sensor from damage but also establishes the field of view.
  • Page 16 The values 0 and the known concentration should be recorded by the logger. This gives a check on the results of calibration. Cyclops-7 Loggers support various Turner Cyclops-7 sensors. The sensor type is shown on a small tag inside the logger.
  • Page 17 A dialog window appears instructing you to place the sensor in the zero solution. This will most likely simply be clear water contained in a bucket. Whatever the solution, the sensor after calibration will report 0 when returned to this solution. Click OK when the sensor is suitably positioned.
  • Page 18 At this time the software reads information from the sensor, selecting all three ranges of the sensor sensitivity. When this is completed a Zeroing of sensor completed dialog appears. Click OK. Precision Measurement Engineering, Inc. (760) 727-0300 www.Turner Designs.com...
  • Page 19 A “Please place sensor in calibration standard of <Calibration Value> (<Unit of Measure>)” dialog appears. In the screen shot above the value of 400 (ppb) is displayed. This information is taken from the Unit of Measure and Calibration Value text boxes and will be whatever is entered in the boxes. Place the sensor in the calibration solution.
  • Page 20 returned to this solution. The same considerations about solution accuracy and reflected light apply in a similar way to those a zeroing. Click OK. At this time the software reads information from the sensor, selecting the best sensitivity range. When this is completed a “Calibration completed” dialog window appears along with the actual calibration results.
  • Page 21 Cyclops-7 Logger. The Logger is now calibrated. Click OK. At this time the calibration is saved on the Cyclops-7 Logger SD card. Note that the calibration has been installed in the sensor and the sensor is calibrated no matter if the results are saved on disk or not.
  • Page 22 A dialog window appears indicating the location where the calibration has been saved. You may later use the host computer’s file copy/paste to move this file to some host computer location. You may choose to leave the file on Logger SD or delete it.

  • Page 24: Cyc7Plot

    Applications on page 1 of this document assumes that the sensor output can be viewed in real time. However this output can only be logged by the Cyclops-7 Logger. A short recording of the measurement must be made, and then the record reviewed, to determine the sensed value.
  • Page 25 DATA folders MUST NOT contain any other files besides files written by the Cyclops- 7 Logger. This folder can be on the SD card from the Cyclops-7 or it can be from a copy of this on your computer’s hard drive.
  • Page 26 You may zoom this plot by drawing a square from upper left to lower right (click and hold left mouse button) that defines the zoom region. To zoom completely out, attempt to draw a square from lower right to upper left. The mouse will scroll the image if the CTRL key is held down.

    Chapter 3: Cyclops-7 Logger 3.1 Overview All of the Cyclops-7 Logger measurements pass from the sensors onto the SD card it contains. Files are transferred to a host computer via USB connection where the Cyclops-7 Logger appears as a “thumb drive”. Measurements may be plotted by Cyc7Plot and files concatenated by Cyc7Concatenate.

    Do not Tighten! The Cyclops-7 Logger tends to get a little tighter during deployment. If you can not open the Cyclops-7 Logger by yourself, find another person with strong hands. This person should grip the black end cap while you turn the white cylinder.

  • Page 31: Battery Replacement

    When replacing batteries use only fresh batteries. Don’t mix battery types. If one battery differs in type or charge level from the other and the Cyclops-7 Logger runs them to full discharge, then one battery may leak.
  • Page 32 The small circular black clip shown to the right of the C7 sensor will be found installed on the logger connector. This can be removed by unscrewing it from the connector, and then gently prying open the ‘C’ clip center piece. Screw one side of the clip fully on to the sensor.
  • Page 33 Be sure both are fully screwed on. If either is not, the clip will hold the sensor in a position where it may not make full contact with the connector. Spray silicone lubricant on the male pins of the sensor. Wipe off any excessive lubricant.
  • Page 34 The clip faces will mate. Note that if the clip is not fully screwed onto the connector it will still appear as shown in the picture above, but the sensor may not be making complete reliable contact with the logger. Snap the remaining clip part onto the clip to secure the sensor to clip connection.
  • Page 35 Slide the sensor support (middle-right in first picture) over the sensor. Note this part has an internal o-ring that comes against the sensor. This is not a water-proof seal. It’s purpose is to firmly secure the sensor within the support. Next screw the sensor guard (middle left in first picture) onto the sensor support.

  • Page 36: Notes

    Should the sensor/connector become loose discontinue use of the logger and contact PME. 3.6 Notes This section collects general notes concerning the instrument.
