Install/Remove Sensors

EXO sensors have identical connectors and identify themselves via onboard rmware; therefore, users can

install any probe into any universal sonde port. e exception is the wiper for the EXO2 sonde, which must

be installed in the central Port 7. Individual ports are physically identied by an engraved number on the

sonde bulkhead. Although the probes are wet-mateable, users should clean, lubricate, and dry the sonde and

sensors connectors prior to installation or service, when possible.

1 Remove probe or port plug.

Remove the calibration cup and sensor guard from the

sonde. Place the sonde on a clean, at surface and prevent

it from rolling. R

emove port plugs by pulling straight out

and place on a clean surface.

If removing a sensor,

use the probe tool in the locking

nut and rotate counterclockwise to loosen. Pull the probe

straight out of the port and place on a clean surface.

Remove hydration caps or buer bottles on probes. Wipe

dry with a clean, lint-free cloth.

2 Clean port and install sensor.

Visually inspect the port for contamination. If the port

is dirty or wet, clean it with a clean, lint-free cloth or

compressed air. Apply a light coat of Krytox grease to the

rubber mating surfaces of the connector.

Insert the sensor into the port by properly aligning the

connectors’ pins and sleeves (male and female contacts);

then press them rmly together.

3 Tighten locking nut.

Taking care not to cross-thread the grooves, nger-tighten

the locking nut clockwise. When the nut is seated against

the bulkhead, tighten it with probe tool until snug. Once

sensors or plugs are installed, reinstall the sensor guard to

protect sensors from impact damage.

Take care not to twist the probe body when tightening

and loosening the locking nut. Excessive twisting of the

probe can damage the connector and is not covered under

warranty.
