Cleaning the Dipmeter
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 it dry
before putting the panel back in. Do NOT use abrasives, partially halogenated hydrocarbons or ketones to
clean the reel.
If you remove the central electronic panel, please ensure you do so in a safe area.
Trouble Shooting
No Sound when the unit is tested
Check the battery by pressing the ON/OFF button. Replace the battery if it’s low and make sure the panel
securing knobs are tight. If the unit still does not sound, remove the central panel and check all of the
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.
To test the system
Firstly, set the sensitivity to 8, hold the probe centre pin against the stud on the back of the reel axle, and at the
same time, touch the probe body against the screw on the frame. The buzzer will sound if the system is ok.
