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.

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.
