B. Electrode Connections
1. Attach electrodes with BNC connectors to sensor input by sliding
connector onto input, pushing down and turning clockwise to lock into
position. Connect reference electrodes with pin tip connectors by
pushing connector straight into reference input.
NOTE: If using a combination electrode with a BNC
connector, a reference electrode is not used.
2. Attach the ATC probe to the ATC jack by sliding the connector
straight on until it is firmly in place. The connector has a special
sealing mechanism, which is engaged, when the connector is
properly attached.
