Use in the Field- Static Water Level Measurement
Cleaning the Meter
1.
Reel the tape down the well carefully, with the "DRAWDOWN CONTROL" switched
"OFF", avoiding the edge of the casing. Hang the unit on the casing with the provided
triangular wire bracket where possible and run the tape over the frame leg to avoid cuts
and nicks.
2.
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 turning down
the sensitivity knob (counter-clockwise) to minimize false readings.
1.
Always clean the meter after field use to maintain performance and minimize contamination
carryover.
2.
Unwind the tape and wash with mild detergent, then rinse well and rewind. The following
cleaning agents are acceptable: 10% Alconox, Joy or Lestoil; methyl, isopropyl and isobutyl
alcohols; hexane and heptane. Rinse thoroughly with water afterwards.
3.
Wash reel if necessary. The central electronic panel can be removed and the reel washed
down. Unthread the securing knobs, disconnect the two wire connectors and remove the
control panel. The reel can be cleaned with Alconox,Windex, Fantastic, Joy, alcohols,
hexane, heptane and mineral spirits. Rinse well with water and let dry before putting the
panel back in.Do not use abrasives or harsh solvents to clean the reel.
1.
Avoid sharp edged casing.
2.
Avoid entanglement with other equipment in wells or boreholes.
3.
Do not
use to plumb borehole depths.
4.
Do not
use as guide to backfilling with sand, etc.- probe may get locked in sand.
5.
Rewind tape onto reel after each use.
Warranty is conditional on these guidelines being adhered to.
