Some products may require periodic checks and certification that they are working properly. A consideration when evaluating equip- ment to purchase is availability and timeliness of service. Getting Wet Most locating equipment is water resistant and designed to work in all weather conditions. After working in rain, never pack equipment wet as moisture can be sucked into the instrument due to temperature changes. If water con- denses on sensitive electronic components, it can cause damage. Always wipe down wet equipment with a cloth, allow it to naturally air dry with any covers or compart- ments open and ideally put it in a warm and dry environ- ment overnight before the next use. Damaged Batteries Damaged or sub-quality batteries can leak inside equip- ment, and their chemicals result in permanent and costly damage to the instrument. Never leave damaged or leaking batteries in the instrument, remove them immediately and dispose of them in accordance with specified requirements. Carefully clean off any chemical residue. Shared Equipment Some organizations have equipment pools from which different users check out needed equipment. In such cases, users must be aware of potential damage caused by oth- er users that was not reported or repaired. Any user that identifies equipment damage should report it to a supervi- sor, manager, other coworker or arrange to get it repaired. Never give damaged equipment to others to use. It makes sense when using unfamiliar equipment to have a simple checklist before using it on a jobsite. • Check the battery condition visually and with the elec- tronic battery status indicator. If batteries don't test good or their condition can't be verified, replace them. • Visually inspect the equipment for any obvious damage or other sign that it might be faulty. If possible, carry out a quick check on a known buried utility line before using the equipment. Self-Test Tips Transmitters of most utility locator systems have an in- duction or broadcast mode that is a simple and effective operational check. Turn on the transmitter and select in- duction or broadcast mode or frequency. Set the locator receiver to the same frequency mode, and from a distance of about 10 ft point it toward the transmitter. Adjust the locator sensitivity as required to get a strong indication. The locator should respond strongly to the transmitter sig- nal. Move closer toward the transmitter, and the indication should increase. Move away, and it should decrease. An additional test is to connect the transmitter connec- tion leads and join their clips to create a direct short cir- cuit connection. Set the transmitter to one of its out-signal modes and at the lowest output signal level or power set- ting. Set the locator receiver to the same operating mode frequency. Place the bottom of the locator in one of the transmitter leads and adjust sensitivity as required to get a strong indication. The locator should respond strongly to the transmitter signal. Move the locator away from the lead, and the indication will reduce. If there is any doubt about results of either of these tests, it is possible that either the transmitter or receiver could be damaged and should be sent to a registered service center for full testing and repair if needed. Always remember that locating equipment is an essential tool for the safe and ef- fective locating of underground utility lines. Failure of the equipment or failure to use the equipment correctly poses the risk that buried lines will not be located and properly marked and that this can result in damages that cost the contractor and owner time and money and risk the safety of construction personnel and the public. Richard Fling is a utility locating product manager at Subsite Electronics. Any time possible damage is suspected, a quick, easy and informal test is to locate a known buried utility line.
