Chapter 6: Panel Indicators and Connectors
Front Panel
The eQCM 15M front panel includes two connectors and two backlighted LED indicators. Each of these are
discussed in turn.
Quartz Connector
The Quartz connector is a male BNC-type connector that is used to connect the eQCM 15M to a quartz crystal
test cell. Your eQCM 15M system includes a BNC cell cable (P/N 985-00124).
Working Electrode Connectors
The front panel has two 2 mm banana connectors which can be connected to a potentiostat's cell cable. This
allows performing EQCM experiments where the quartz crystal additionally serves as working electrode. The
W.E. jack is hereby connected to the green Working Electrode lead of the potentiostat's cell cable and the W.S.
jack is connected to the blue Working Sense lead.
The eQCM 15M system also includes two 2 mm pin to 4 mm banana socket cables to accommodate different
cable lead connectors.
Power LED
The Power LED normally glows a steady blue when the eQCM 15M is turned on. It is off when:
The Power switch is off.
USB cable is not inserted or connected to a computer, or the computer not powered up.
USB LED
The USB LED is a green LED that blinks continuously during data-acquisition. Higher data-acquisition rates may
make the LED appear lighted continuously.
