If you wish to connect several different instruments that do not
have their own power supply, then it is possible you will need to use a
USB hub that does have its own power supply (self powered). The USB
(OTG) connector of the 899 Coulometer is not designed for supplying
power to several devices with elevated electricity requirements.
Also observe the instructions in the Appendix of the more detailed man-
ual.
