Bacharach Leakator 10 - Manual (Page 14)

Procedure:
1. Turn OFF instrument.
2. Pry sensor out of its socket using a small flat-blade screw-
driver (Fig 4) and discard.
3. Remove battery cover.
4. Remove old matching resistor (Fig 5) and discard.
5. Locate new sensor’s matching resistor; then cut and bend
the resistor leads using the forms that are molded into the
battery cover (Fig 6). Note that If the resistor leads are cut
too short, the instrument may not function.
6. Insert new matching resistor into printed circuit board,
and plug new sensor into socket at end of probe. Notice that
the sensor’s six pins and the socket are symmetrical and not
keyed, thus permitting the sensor to be plugged in two ways.
The socket, however, is wired so that it doesn’t matter which
way the sensor is installed.
7. Install battery cover.
8. Test instrument response (refer to Section 4.2).
