RQCM – RESEARCH QUARTZ CRYSTAL MICROBALANCE
OPERATION 3-3
3.3.6.1 Crystal Face Mating Connector
The mating connector to the Crystal Face Connector is a 2.5 mm male plug. The plug carries two
contacts, the tip and the sleeve (see Figure 1). However, only the tip contact is used to connect to
the working electrode of a potentiostat. You can solder the working electrode wire directly to the
tip terminal. The sleeve terminal is not used. You can disregard it or break it off.

3.3.7 FINE AND COURSE CAPACITANCE ADJUSTMENTS
The Fine and Course capacitance adjustments are used together to cancel out the unwanted static
capacitance of the crystal, the crystal holder, and the connecting cable. Refer to Section 3.4 for
procedure on the proper adjustment.
