Chapter 1 OVERVIEW

DS-72

1.5 Connecting the Electrode

1.5.1 Electrode Connector

1.5.2 Temperature Connector

If the temperature connector is unconnected or the connection is wrong, the MTC set
temperature is displayed as the liquid temperature.

Insert the groove of electrode connector
by fitting with the connector socket pin
of the instrument.

Do not insert it with force when the pin
and groove are misaligned.

Turn the electrode connector to the right
along the groove to plug the connector.

Put the connector cover on the
connector.

Just push the cover on the instrument.
Do not screw in it.

Insert the temperature connector into
the jack socket on the instrument.

CH2 reference electrode

CH2 measurement electrode

CH2 for temperature electrode
