Depth & Current Estimate - 3M Dynatel 2250M Series Operator's Manual

Expanded Mode
When the third ring of the speaker icon is dotted or broken and 'xpnd' appears
below the speaker icon, the receiver is in "Expanded" mode. The audible
response of the receiver sharpens, allowing the locator to detect very small
signal changes.
Depth and Current Estimate
To verify target path, depth and current can be helpful tools.
Pinpoint the cable or pipe being located.
Lower the tip of the receiver to the ground and press Depth [SK].
The depth to the target cable or pipe is displayed in units, as 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. The milliamp
reading is an actual current measurement.
.
There are two options for measuring depth. Live depth is a continuous
measurement. 1-Shot Depth is an averaging of the depth reading. When in
1-Shot mode, the unit will average the depth reading for three seconds, and
then display the result on the screen. Press Depth [SK] to alternate between
the two modes.
