Current Measure: mA (miliAmperes) of current flowing on the conductor. current current Use Current Measure as an aid for distinguishing utilities in close proximity. The Current Measure will generally be the highest on the utility you are connected directly to, regardless of the utility’s depth. depth TW-82 Transmitter The Transmitter has two controls: The Button has a dual function: & . 1.

TW-82 RECEIVER TW-82 TRANSMITTER Display - Continued 2. Battery Strength: When battery life declines to less than 1 hour (estimated) of operation the battery indicator outline will be illuminated with no segments. When the batteries reach the end of their useful life, the screen will go blank and the battery icon will flash before the Receiver shuts off. Expect about 60 hours of battery life from a set of two D-cell alkaline batteries. 3.

TW-82 TRANSMITTER TW-82 RECEIVER INDUCTIVE LOCATING Inductive locating is most effective with the Transmitter straddling the utility as illustrated, with the utility perpendicular to the Transmitter’s batteries. If the utility direction is unknown, place Transmitter on the ground, power on, and sweep the Receiver a complete 360º around the Transmitter, keeping at least a 25-foot (8-meter) distance between the Transmitter and Receiver. If unsuccessful, move the Transmitter to another location.
