3M 2250M-iD, 2273M-iD manual Locating Active Duct Probes Sondes, Determining ADP Depth

Page 35

Note: In order to measure the depth and current accurately, the operator must pinpoint the target pipe or cable, and the receiver handle should be in-line with the target path.

−− While in Dir Pk mode, find the highest Signal Strength [10].

−− Lower the tip of the receiver to the ground. Twist the receiver left and right while watching the signal strength.

−− When the highest Signal Strength [10] reading is displayed, the handle of the receiver is in line with the target pipe or cable.

Occasionally, a signal will appear on adjacent cables or pipes. Compare the relative and actual current readings (value that is under the relative current value and in mA units) over each path to help determine the target path. Current readings will be significantly less on the adjacent cable compared to the target path.

19.As tracing proceeds, remember that the most powerful signal is near the transmitter. As the receiver gets farther away from the transmitter the Signal Strength [10] decreases. It may be necessary to readjust the gain as needed to ensure that there is adequate signal for the receiver to operate. Press the Gain [4] up or down when the Bar Graph [11] is no longer visible (too little signal) or when the Bar Graph [11] is closed (too much signal).

20.Trace the path until you reach a logical termination point (i.e.: terminal, meter, cabinet, etc).

11. Locating Active Duct Probes (Sondes)

1.Press On/Off [1] on the receiver.

2.Press Locate/OK [5].

3.Press Cable/Pipe [SK].

4.Press Mode [SK Toggle] to select Special Peak (Spl Pk).

5.Press Freq [SK].

6.Press Active [SK Toggle] to select the 33kHz frequency (for a 33 kHz Sonde or Active Duct Probe (ADP)).

7.Press Locate/OK [5].

8.With the receiver handle perpendicular to the conduit path, locate the ADP position by moving along the path until the strongest signal is found. Adjust Gain [4] up or down when the bar graph remains either fully open or fully closed.

9.Refer to the ADP operating instructions for further information.

A. Determining ADP Depth

1.Place the tip of the receiver on the ground directly above the located ADP position.

2.Maintain the handle orientation perpendicular to the target path.

3.Press Depth [SK] in the Cable Locate display.
