solenoid is possible by decreasing the volume and taking your time.
The lower the volume is, the more accurate you can be.
Slowly start moving the receiver in an X pattern above the high-
pitched area, continue reducing the volume while moving the tip of
the receiver closer to the ground. Between proximity of the receiver
tip to the ground and the reduction in volume you can tell exactly
where the valve solenoid is. Use a pointed probe to find the outline of
the valve box before excavating. This will ensure that unwanted
damage isn't a result of your locate. Once the valve is located, verify
that it is indeed your target either manually, with the Pro48, or from
the controller.
There may be more than one valve on the cable being traced. You may
wish to continue past the first valve located to determine if other
valves are also located on this wire.
Inductive Clamp Mode – To use the IC4 clamp, plug the clamp into the
clamp receptacle on the Pro881™ transmitter and place the
transmitter in "INDUCT" mode. Clamp the IC4 around the cable or
metal pipe to be traced. For best performance, orient the clamp so
that the side with the wired handle is closest to the cable. You can also
increase the effectiveness of the clamp by wrapping the wire around
the clamp jaw as many times as possible. Like a transformer, the more
wraps, the more power.
Please note, the clamp must be placed between grounding points on
each end of the cable and the cable must be grounded on both ends
for the clamp to work. The clamp induces current onto the cable and
the current will not flow if the cable isn't grounded on both ends.
Note: INDUCT Mode operates using Null reception only.
