Standard USB1.0 or 2.0 (type A) inputs on your computer do not provide enough power to
power up your eQCM 15M. Only USB3.0 inputs provide at least 0.9A/4.5W power. Use the powered
USB-hub if your computer has no USB3.0 input, otherwise your eQCM 15M cannot be powered.
Only this USB-type provides enough power
An A/C USB cable has different connectors on each end. The end with a wider, rectangular-shaped connector
(type A) plugs either directly into a USB port on your computer or you can plug it into a power USB-hub that is
connected to the computer. The end with a smaller connector (type C) plugs into the USB port on the
eQCM 15M (see Figure 4-2).
You can also safely remove the USB cable without powering down the eQCM 15M and your computer.
However, be aware that this may have undesirable consequences if the system is currently taking data or
performing an electrochemical experiment.
Power-Up Test
Before you make any other connections to your eQCM 15M, check that the instrument is at least nominally
functional.
One quick test is to turn on the eQCM 15M and watch the blue Power LED indicator on the front panel. After
connecting DC power to the instrument, turn press the Power button.
