Introduction
The CBF100 makes it easy to find the circuit breaker or fuse that
supplies a specific power receptacle or light switch automatically. Just
plug in the transmitter then make a few quick scans of the power panel.
There’s no need to shut off power in a hit-and-miss effort to find the
right breaker - that’s a great benefit in automated office environments!
Safety Notes
Proper use of the CBF100 typically makes the process of finding the
correct fuse or circuit breaker safe and sure. The non-contact sensor
allows you to instantly confirm that the circuit you switch off at the
power panel is the same circuit that is powering your transmitter.
Follow these tips when using this instrument on electrical circuits:
• Use only the specified range of input power to the transmitter
(90 to 120 volts AC)
• Use lock-out / tag-out procedures when performing
maintenance on disabled circuits
• Use a multimeter to confirm there is no cross-feed power on
the disabled circuit
• Check for power on near-by circuits before touching or
reaching across them
• If it becomes necessary to remove the panel cover to make
positive identification of a circuit breaker do not contact
live bus-bars
• Perform only those maintenance tasks which you are qualified
to do
Controls and Indicators
Power on LED's
Some preparation is required to attain best results with this instrument.
Some devices, such as battery charger's, light dimmers, and motor
control rheostats can generate false signals. Unplug or turn off all
these devices that are connected to your power panel. You can make
a quick check for false signals by using the receiver on your power
panel prior to plugging in the transmitter. If a signal is detected, check
for one of these devices or any other that modifies AC power (like an
AC to DC converter).
Operating Instructions
1. Plug in the transmitter to a live wall outlet or suitable socket adapter.
• Ve r i fytransmitter is on by observing the LED is lit.
2. Turn on the receiver holding it at least 12" away from any circuit.
• Ve r i fythe LED is lit (on the topnear the switch) and remains lit.
NOTE: The audible tone sounds once or twice, then stops.
3. Holding the instrument with the switch up (see figure 2), move
the receiver from top to bottom over the breaker's or fuses in the
power panel, touching each breaker.
NOTE: Those breaker's or fuses that provided "hits" (audible tones)
as the receiver passes over them.
4. Pull the receiver away from the panel (at least 8") and repeat step 3.
• With each pass over the power-panel, the receiver becomes
less sensitive until a hit will occur only on the breaker or fuse that
carries the transmitters signal.
5. Note or mark the appropriate breaker
• Use lock-out / tag-out procedures when working on circuits that
you turn off at the power-panel for maintenance purposes.
NOTE: In rare circumstances the receiver will hit on multiple
circuits, then sensitivity will drop below a level that will provide a
hit on the appropriate circuit. In this event, turn the receiver off and
repeat the process from the beginning. If a single breaker cannot
be isolated, the panel cover may have to be removed to expose
individual wires. Test the wiring from the breaker's in the same
manner indicated above.
