HAZARD ALERT INFORMATION BE AWARE OF SAFETY INFORMATION This is a safety-alert sign. This is placed in the manual and on your equipment to alert you to the potential for bodily injury or death.
Page 2 DANGER : High Voltage. Cutting high voltage cable can cause DEATH or ELECTROCUTION. Expose lines by a non-destructive means before excavating. DANGER : Traffic Hazards can result in death or serious injury. Avoid moving Vehicles. Wear high-visibility clothing. WARNING : Buried lines. Always confirm your depth estimate by exposing target line by a non-destructive means.
Page 3 2. Introduction This equipment is the high performance digital measurement equipment to measure the location and the depth of buried cable / metal pipe from the ground. By adopting the most recent microcomputer technology, the digital correction of the measurement data realizes stable and high precious measurement. - Principle measurement method - When current flows through a buried cable/pipe, an alternating magnetic field is generated around it.

Page 18: Frequency Setting
7-2. External coil mode Use 9.5 kHz, 38 kHz or 80kHz External coil supplied as an option. Use this mode if object is accessible. An induced current, generated by the coil in the External Coil attachment, is applied directly to the exposed part of the cable / pipe to be located.
Page 19 External coil mode Make sure that the cable is grounded at both ends. Do not put the coil close to or around the ending or middle ground. Unmeasurable Signal to ground Intermediate ground will not trace. * If the cable is submerged in water, you can use the coil attachment in the water. The coil attachment is WATERPROOF.
Page 20 7-3. Indirect (Inductive) mode If there is not direct access to the object line, the Transmitter can apply AC current ( signal ) to the line directly below the Transmitter. Note: When using the indirect mode, set the depth mode of the receiver to 0-5m (0-16ft.) . When nothing is connected to the transmitter, Indirect mode automatically selected.
