Connecting The Uat-600-T Transmitter - Amprobe AF-600 Manual De Usuario

3. Optionally, you can precisely detect and mark cable locations using the UAT-600-R receiver. Refer to the
UAT-600 User Manual for detailed instructions how to locate underground utilities.

6.2 Connecting the UAT-600-T Transmitter

�Warnings: Read Before Using
• Use the UAT-600-T Transmitter only as specified in UAT-600 User Manual or the protection provided by the
instrument may be compromised.
• Check and read all safety information in UAT-600 User Manual before use.
• Inspect the test leads before use. Do not use if insulation is damaged or metal is exposed.
• Check the test leads for continuity. Replace damaged test leads before using the Product.
• Never operate the Product with the battery cover removed or the case open.
• Use extreme caution when working around bare conductors or bus bars. Contact with the conductor could
result in electric shock.
• Disconnect and isolate the cable on both ends before connecting the UAT-600-T to the cable.
Setting up the Transmitter
1. Turn the Transmitter on by pressing power button for 2 seconds.
2. Connect the black and red test leads to the Transmitter inputs. The Transmitter will switch automatically to
Direct Connection Mode and the display will show the direct connection icon
3. Insert the ground stake into the ground a few yards away, perpendicular to the line. Connect the black lead
to the ground stake with an alligator clip.
4. Connect a red test lead to the target line.
5. Pres Hz button repeatedly to select "A-LO" (A-Frame low signal) or "A-Hi" (A-Frame high signal). Use "A-
LO" for higher accuracy pinpointing. Use the "A-Hi" setting if the line to be surveyed is long or the fault
resistance is high.
6. Press the "+/-" buttons to set the output to level one. Increase the level if the resulting signal strength is
poor. Increasing the signal unnecessarily may result in the signal "bleeding off" onto other services and
creating misleading "ghost" signals. It will also drain more power from the battery.
Note: When connected, the Transmitter will emit a beep tone. The better the connection to the line and
ground, the faster the beep tone will be. Check for a good connection by disconnecting and then reconnecting
the red lead. It is also possible to check the signal current being supplied by the Transmitter by entering the
user menu and selecting the mA option.
Things that can affect the quality of connection are a rusty pipe connection point (clean the connection area
with a wire brush) or poor grounding. To improve the connection quality due to poor grounding, try inserting
the stake into damp ground. If necessary, dampen the surrounding ground with water. If grounding is still an
issue, try connecting test lead to a manhole cover surround. Avoid connecting to fence railings as these may
create return signal currents along the fencing that will interfere with the locating signal.
Note: If the signal level bars do not fill, this indicates that the impedance of the line is limiting the current
output. Increasing the output beyond this point will not increase the signal. If more signal is required, check
the quality of the connection to the line and ground.
When connecting to large diameter pipes and cables, it is sometimes not possible to find a suitable projection
to apply the alligator clip. If the material is ferrous, use a magnet to make contact to the line and then attach
