Use in the Field *

2.6

Reel the tape down the well carefully, avoiding the edge of the casing. Hang the unit on the
casing where possible and run the tape over the frame leg to avoid cuts and nicks.

When the unit sounds, carefully measure the depth to water from your reference point by
slowly lowering and raising the probe to the air/water interface. Raise the probe, shake off the
water and repeat the measurement. In wells with cascading water, reduce the sensitivity by
pressing the (-) button to avoid false signals.

The probe is rated to full depth and can be used to measure depth to bottom of well. Reel the
tape until the probe touches bottom and the tape becomes slack. DO NOT let the probe fall
under gravity or it will be damaged when it hits the bottom of the well. DO NOT use the unit to
measure sand backfill as the tape and probe may get "locked" in the backfill.

Wind the tape back onto the reel, removing any excess moisture and dirt.
* Important: Ensure that the panel securing nuts are tight before use.
Note: Intermittent beep indicates unit ON. Beeping shuts off automatically 5 minutes after
last use.

Cleaning the Dipmeter

2.7

Always clean the meter after use in the field to maintain optimal performance and extend the
life of the unit.

Unwind the tape and probe and wash with a mild detergent. Rinse well, wipe and rewind onto
the reel. The tape and probe can be cleaned and degreased with the following: soap solution,
naptha alcanox 10%, detergent 10%, Lestoil; methyl, isopropyl and isobutyl alcohols; hexane,
heptane and fully halogenated freon. Rinse thoroughly with water afterwards.

Wash reel if necessary. The central electronic panel can be removed and the reel washed
down. Unthread the panel securing knobs and carefully pull out the central panel. Disconnect
the panel from the tape. The reel may be cleaned with the following: soap solution, naptha
alcanox 10%, Fantastic, Windex, Joy, Top Job, Mr. Clean, Formula 409; hexane, heptane, white
kerosene, mineral spirits; methyl, isopropyl, isobutyl and 1 + 3 denatured alcohols; freons TF +
TE. Rinse well with water and let dry before putting the panel back in. Do NOT use abrasives,
partially halogenated hydrocarbons or ketones to clean the reel.

Trouble Shooting

2.8
No Sound when the unit is tested

Check battery by pressing ON button. Replace battery if low and make sure panel securing
knobs are tight. If unit still does not sound, remove central panel and check all connections.

Check probe conductor to make sure it is clean and not crusted with mineral deposits. Check
tape/probe connection for any breaks.
Continuous Sound when the unit is turned on or probe removed from water

Make sure probe conductor tip is clean.

Check for excess moisture on the back of the electronic panel.

Check probe/tape connection and tape for any breaks or leaks where water might get in.
