Frequently Asked Questions

Q: Is there any way to measure depth in Passive Mode?
A: No. However, after tracing the buried line in Passive Mode, you can connect the
transmitter to measure depth in Trace Mode.
Q: The speaker doesn't always produce a tone when I'm near the conductor. Do I need to
press the Signal Reset button?
A: No. This feature is provided for convenience—it provides a second method of feedback
for the user. Tone indicates that the signal level is above 75 on the LCD, or that all of the
Signal Strength lamps are illuminated.
Q: What do the dashes on the LCD indicate?
A: There are two possibilities:
(1) The receiver is beyond the range of the signal. Press and release the Signal Reset
button. If the dashes remain, scan the area while pressing and releasing the Signal
Reset button until the receiver acquires the signal.
(2) The BLL-200 wasn't set up correctly:
• If using the receiver alone, verify that the receiver is in Passive Mode and that the
transmitter is turned off. Also check that the batteries are in good condition
(BAT on the LCD indicates that the batteries are low).
• If using the transmitter and receiver together, verify the following:
– the transmitter is turned on
– the transmitter is set to the correct mode
– batteries are in good condition (Low Power lamp is not illuminated on the
transmitter, and BAT does not appear on the LCD of the receiver)
– the receiver is in Trace Mode
Q: Under Direct Connection the manual instructs, "If tracing a live circuit, connect the
transmitter at the endpoint of the circuit or branch — not in the middle or at the source."
What's the difference?
A: When the transmitter is placed at the endpoint of a branch, the full signal strength is
transmitted along that branch. This will provide optimum tracing results.
When the transmitter is placed in the middle of a circuit or at the source, the signal
strength is diluted among all of the branches. The relatively weaker signal will not be as
easy to trace.
Also, additional conductors are more likely to be found near a source. These other
conductors may pick up some of the signal and produce interference.
