An optional Tape Guide, to prevent the edge of the well casing from damaging the tape, is also available from Geotech. Figure 2-1 is an example of the two parts. Figure 2-1: Tape Guide (optional), Tape Weight (optional), Tape Leader Guard Optional Tape Weight Installation Attach tape weight to tape near probe end being lowered into well.
To turn the unit off, rotate the switch fully counter-clockwise until the switch clicks. If the ETL WLM+T is not used and is stored for longer than three (3) months, remove the battery to prevent battery leakage, which can cause internal damage.
Use a 9V alkaline battery only. Cleaning The ETL WLM+T can be cleaned with mild detergents such as trisodium phosphate (TSP). If other detergents are used, take care to select detergents that are compatible with PTFE, PVDF, and stainless steel. The reel should not be submerged in any liquid, but may be cleaned with a damp cloth.
The conductive contact is dirty (causing bridging). Clean the contact (Section 4: System Maintenance). There is a short in the tape and/or probe. Replace tape and/or probe. The circuit is malfunctioning. Contact Geotech Service. For technical assistance, call Geotech Environmental Equipment at 1-303-320- 4764 or 1-800-833-7958...
