  • Page 7: A Short Exercise

    1.3 A short exercise Let’s do a quick exercise to show how easy the Scuba is to use. We will connect the instrument to a PC, calibrate conductivity, and check the calibration log for the conductivity calibration information. Connect your Scuba to your PC with the USB adapter and either a data cable or underwater cable.

  • Page 8: Scuba Basics

    2.1 Deployment specifications The Scuba can be used in natural water up to 50 degrees C and 200 meters deep, except that ISE’s are rated to 10 meters deep, and TDG sensors and low-range depth should go no deeper than 25 meters.

  • Page 9: Underwater Cables

    A sequence of red and amber LED flashes tell you the voltage of your battery pack if you have activated logging. When you first power-up your Scuba, the red LED will blink five times to indicate that logging is activated and to indicate the first 3.5 volts of battery power, and then one amber blink for each volt, and one red blink for each half volt.

    Eijkelkamp’s USB converter converts your Scuba’s data stream to a USB port. Newer models have a power port on the side that you can use to provide power to the Scuba if USB power is insufficient, or to protect your laptop’s battery. The connector is fairly standard for power supplies, so you can plug in many third-party power supplies –...

    Click the “Scuba logging is OFF” (or, “Scuba logging is ON”) hot button to enable or disable the Scuba’s logging function. It lets you tell the Scuba that you will be deploying it in the field for unattended logging. Clicking the hot button toggles the logging on and off. Generally, logging should be off – turn logging to ON only when you’re preparing for unattended deployment.

    0.88 to mimic the readings that you would get with the other turbidity sensor. The software specific to turbidity has changed as well. In most cases, you can update your Scuba’s software with these new software if you wish to take advantage of the new features dealing with turbidity.

  • Page 19: Sensors And Calibrations

    4.2 Basics of parameter calibrations The Scuba never guesses parameter values, so you have to calibrate it from time to time by simply telling the instrument what it should read in a calibration situation for which the correct parameter value is known. Here’s the general procedure;...

  • Page 20: Choosing Calibration Standards

    4.3 Choosing calibration standards For best results, choose a calibration standard whose value is close to what you expect to see in the field. For example, calibrate with a 1413 μS/cm specific conductance standard if you expect to see specific conductance readings between 500 and 1000 μS/cm in the field.

  • Page 21: Calibration Record ("Cal Log")

    If your response is 80 μA, your SRF would be 80%. When you press the OK button to accept a calibration, the Scuba automatically accepts your calibration if the SRF is between 60% and 140%. If the SRF falls outside that range, you will be cautioned to check your standard value, make sure the sensor is clean, make sure the reading has stabilized, etc.
  • Page 22 The manufacturers of optical-DO sensors recommend that you not calibrate the zero-DO point. However, we support zero-DO calibration in the Scuba software, and think it’s a good idea to check your sensor’s zero from time to time in either of three ways: Dissolve a few grams of sodium sulfite and a pinch of cobalt chloride in a half-litre of tap water.

    Eijkelkamp’s depth sensors are usually inside the instrument, with a small pressure port that can be seen on the outside of the Scuba bottom cap. They require no regular maintenance, but you might check occasionally to make sure the...

  • Page 25: Turbidity

    Depth calibration is nothing more than “zeroing” the sensor in air, where one assumes the depth to be zero: Make sure the Scuba is not in the water. Follow the Scuba control software’s calibration instructions. Notice that the depth sensor cannot distinguish between water pressure and the air pressure over that water (i.e.

    Available on Scuba 75, 90, and 105 models with turbidity sensors. Eijkelkamp’s mini cleaner is used for sensor brushing when the Scuba does not have a turbidity sensor (and hence cannot have the extended turbidity brush). It can be programmed for frequency of brush cycles and number of sweeps per cycle.

    Judgment gained from observing your field conditions and data requirements tells you when to maintain sensors. If you are logging data over long periods, the time when you collect your data from the Scuba is a good time for maintenance and calibration (2.10).
  • Page 46 You’ve been paying € 175 a year to replace DO caps, haven’t you? It’s OK; lots of people have been in the same boat. Now that you are a Scuba owner, you can expect your DO caps to last five years or more. You can see the condition of your cap when you calibrate DO.

    External Battery Pack is shown as cable voltage. There is no fixed cut-off point, but any time the battery pack or cable voltage drops below about 5 VDC, the voltage may not be adequate for the Scuba to boot properly.

  • Page 50: General Faq's

    Can I add sensors to my Scuba? The Scuba can handle as many as 12 sensors. If you have fewer than 12 and wish to add one or more sensors, we can do it. Why do you build the Scuba the way you do? Unlike the products of lesser manufacturers, the Scuba uses the same basic electronic and mechanical components regardless of how many sensors you order.
