D. Induction Peak (Ind Pk)

Locate/OK [5] + Cable/Pipe [SK] + Mode [SK] + Ind Pk [SK Toggle]

If you cannot make a direct connection, or use the 3M™ Dyna-Coupler Clamp to apply a locating signal on the target, use the induction method. This method uses the internal coil of the transmitter to generate a magnetic field.

The Induction Peak mode of the receiver is a mode in which the upper antenna of the receiver is tuned to minimize distortion from the magnetic field of the transmitter.

Left or Right of Target Path

Directly Over Target Path

E. Expanded Mode

When the third ring of the speaker icon is dotted or broken and ‘xpnd’ appears below the speaker icon as shown, the receiver is in “Expanded” mode. This mode is used for pinpointing a target cable or pipe. The area of response of the receiver narrows, allowing the locator to detect very small signal changes. Press the Speaker Volume Control [2] key to activate the "Expanded" mode.

8. Depth and Current Estimate

Verifying the target path, depth and current can be helpful tools.

1.Pinpoint the cable or pipe being located.

2.Lower the tip of the receiver to the ground and press Depth [SK].

−− The depth to the target cable or pipe is displayed in the units specified in the receiver set up menu. The bold current reading is a relative current measurement. This reading can be compared to the current reading that alternately flashes with the frequency on the transmitter to help identify the target cable/ pipe. The highest relative current value will be the target cable/pipe and will compare closest to the transmitter relative current value. The milliamp reading is an actual current measurement.
