13 How often should I change the pH electrolyte?
To be safe, change your electrolyte every month or so. That’s probably overkill, but changing electrolyte takes only a
minute and is basically free. (4.10)
14 Where do I buy calibration solutions for the various sensors?
You can buy most calibration solutions from Eijkelkamp, lab supply companies, or most catalogue houses (4.2, 4.3).
7.4 Communication and software
1 What is the range of the Bluetooth?
Hard to say because of the differences in Bluetooth technology over the years, variations in data display Bluetooth
implementations, and because Bluetooth is different for Android and Apple applications. You can estimate Bluetooth
range of your Bluetooth by connecting your Scuba to your Bluetooth Battery, pairing with a data display, and then
walking away with the data display until the connection breaks. (6.3, 6.4)
2 How long does the Bluetooth battery take to charge?
We recommend charging overnight, but you can get a partial charge in an hour or two. (6.3)
3 How does the Scuba communicate (SDI-12, etc.)?
Scubas speak RS-232 as their native language, but Eijkelkamp provides converters for SDI-12 and MODBUS if you
prefer. (Scuba Comm Protocol, Scuba SDI-12 Adapter, and MODBUS Communications)
4 What com port should I use?
Most people should never have to worry about choosing a COM port; just let the PC do the work. (3.4)
5 Is the coloured top line an average of the values or the latest readings?
No; the data in the coloured band is the most recent line of data obtained from your Scuba. (3.2)
7.5 Deployment and applications
1 How long can I expect my batteries to last?
Battery life is difficult to predict because it varies with logging interval, quality of batteries, number and type of
sensors, and water temperature. Battery life is best determined by experimenting with your specific Scuba in your
specific applications. (5.9)
2 For my battery pack when looking in the log file at battery voltage, at what point will the Scuba stop logging?
The Scuba can show the voltage provided via the cable and the voltage provided by an Internal Battery Pack. The
voltage provided by an 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. (5.9)
3 How do I deploy my sonde when there is no bail hook? Is it OK to hang by the cable? How much weight will the
cable hold?
When properly attached, the Scuba underwater cable can support well over 50 pounds without using a bail kit. You
can hang the Scuba by the underwater cable if the load is not likely to exceed 50 pounds. (2.4)
4 How do I attach the underwater cable to the sonde?
Please see 2.4.
