the device be stored in a shipping container or in a plastic container with electric shock protection in a
non-freezing and dry environment. The empty end left by the sensor on the main unit should be sealed
with a port protection plug.
7.3 Cable maintenance
When operating in the field, care should be taken not to place any non-waterproof cables (ie any cables
other than waterproof underwater cables) near any source of water. Keep the joints dry at all times.
Use a silicone grease to properly lubricate the sealing surfaces of all subsea joints.
Keep all cables clean, dry, and stored (tidy and coiled) in a large plastic container.
Do not allow the cable to be less than 6 inches in diameter, as this will damage the cable.
Do not knot the cable or use a clip to mark a certain depth.
Any cable should be protected from wear, unnecessary tension, repeated bending or severe bending (such
as railings) during use.
7.4 Sensor damage check
Check the appearance of the sensor for damage. If there is any damage, contact the after-sales service
center for replacement to prevent the sensor from entering the water due to damage.
7.5 Host battery replacement
1. Place the multi-function probe horizontally on the work surface to prevent water from leaking into the
multi-function probe battery compartment;
2. Unscrew the battery cover screw counterclockwise, as shown in Figure 9.
3. Unplug the cover from the housing and slide the old battery out;
4. Throw away the old battery and insert a new one, as shown in Figure 10. Observe the polarity
identification on the inside label. If the battery is installed in the wrong direction, it may cause serious
injury and damage to the instrument;
5. Slip on the battery cover O-ring with a small amount of silicon, reinsert the cover into the multi-probe
housing, and tighten the screw clockwise.
