OPERATION
Waterra has designed the HS-2 Oil/Water Interface Tapes as lightweight,
compact, oil/water interface measuring devices. They feature both enclosed
reels with very narrow profiles and more traditional open reels. The HS-2 closed
reel can carry up to 30 meters or 100 feet of flat tape. The HS-2 open reels can
carry 50, 75 or 100 meters or 250 feet of flat tape.
The electronics module located in the hub of the unit contains the batteries,
electronic circuit board, buzzer, light, and on/off membrane switch.
The on/off switch has a built-in timer so that the unit will automatically turn
itself off after three minutes. This feature is designed to extend battery life.
When the HS-2 is turned on, the battery light will be illuminated continuously.
Low batteries are indicated by a flashing signal from the battery light indicator.
When the HS-2 Interface probe contacts a hydrocarbon liquid, the buzzer will
emit a continuous tone and the oil light will illuminate. When the probe contacts
water, the buzzer will emit an intermittent tone and the water light will illumi-
nate. There is no sensitivity adjustment available for the HS-2 meter.

open reel — counter clockwise
The HS-2 open reel winds the flat tape
back onto the reel by rotating the handle in
the counter clockwise direction.
closed reel — clockwise
The HS-2 closed reel must be rotated in
the clockwise direction to wind the tape
back onto the reel.
OPERATION
The flat tape on HS-2 open reels and HS-2 closed reels must always be wound
back onto the reel by rotating the handle in the correct direction, however the
direction of winding is not the same for both of these reel formats.
Winding the tape back onto the reel in the wrong direction will cause problems.
Additionally it is important with both reel designs that the tape be spread evenly
across the spool as it is wound back into the reel. This can be done by rocking
the reel from side to side as the tape is being wound up.

BATTERY REPLACEMENT
Replace the batteries when the indicator light shows that they are worn or at
least once per year.
The batteries can be accessed by removing
the two screws located on the Front Panel
above and below the label. Remove these
screws with a Phillips screwdriver and then
carefully lift the Front Panel from the front
hub. Turn the Front Panel upside down and
place the two screws in the panel.

The battery pack is located on the rear side
of the Main Circuit Board which is now ex-
posed. You must remove the four screws
which hold the Main Circuit Board in place to
gain access to the battery pack. Remove the
two screws at the top and the two screws at
the bottom of of the Main Circuit Board and
place them in the Front Panel.
Remove the Main Circuit Board by using a
small flat screwdriver and placing the blade
of the screwdriver under the edge of the
Main Circuit Board, alternating from the left
side then the right side of the board. This will
disconnect the board from the two connec-
tors located on the back side.
Once the Main Circuit Board is removed, turn
it over and replace the worn AA cells with four
fresh Duracell AA batteries. Be sure to orient
the batteries in accordance with the direc-
tions supplied on the battery pack. Return
the Main Circuit Board to the reel by carefully
lining up the pins with the connectors (4 pin
connector on the left, 6 pin connector on the
right) and press the Main Circuit Board into
position.
Replace the four screws in the Main Circuit
Board. Replace the Front Panel to the hub
and return the two screws to the correct
holes, above and below the label. Care must
be taken not to over tighten the screws. Over
tightening may strip the threads from this
part.

ROUTINE MAINTENANCE
In order to maintain your HS-2 in the best working order, some routine mainte-
nance is required. The flat tape should be inspected for cuts and abrasions on
a regular basis. Severely damaged tapes should be replaced. Contact Waterra
if this is required.
The tape should be completely spooled out of the reel and cleaned with a damp
cloth and the reels will also need to be wiped down to remove sand and mud.
Be sure to wind the tape back onto the reel in the correct direction (see Probe
Holder & Winding the Reel).
Check that the tape is wound onto the reel in an even manner. Do not allow the
tape to accumulate on one side of the reel.
The probe tip should be cleaned on a regular basis with a toothbrush and wa-
ter to remove any material that may accumulate there. A clean probe tip will
increase meter accuracy.
Replace the batteries when the indicator light shows that they are worn or at
least once per year. See the battery replacement instructions for directions.
water resistance
The HS-2 is designed to be water resistant, however these units are not water-
proof. Do not immerse the HS-2 or the HS-2L as this will damage the electron-
ics and flood the unit.
cleaning and decontamination
The HS-2 should be kept as clean as possible as this will help keep the units in
good working order. The flat tape can be cleaned by spooling the tape out of the
reel into to a large bucket, allowing it to soak in a cleaning solution. The recom-
mended detergent for this is Alkanox.
Rinse the tape in clean water and pass the tape through a clean cloth as it is
wound back into the reel.
Do not immerse the reel and electronics! The reel can be cleaned with a clean,
damp cloth. If the inside of the reel becomes contaminated or is excessively
dirty, the tape and reel should be disassembled for a more thorough cleaning.
