The sensor cable is NOT supplied as standard. A cable can be obtained by contacting
Kahn Instruments (see www.kahn.com for details).
Cable connection to the Easidew transmitter is made via the removable connector.
Removing the central screw enables the connector terminal block to be removed from
the outer housing by using a small screwdriver to pry it clear.
