1. INTRODUCTION
1.1 Description
The FD650/R is a combined AC voltage detector and fuse finder receiver
(when used in combination with the FD500/T or FD600/T transmitter).
As a fuse finder the FD650/R can be operated with either manual or
automatic setting of its sensitivity threshold to find the fuse or circuit
breaker that produces the maximum signal.
In manual mode the press of a push-button will set the sensitivity threshold
to bring the detected signal to mid scale on the bar graph.
In automatic mode the FD650/R will automatically set the sensitivity
threshold every time a signal of a greater magnitude is detected, to bring it
onto the bar graph scale.
In either mode the buzzer will continue to sound when a signal is present,
even when the signal is too small to be shown on the bar graph due to the
sensitivity setting.
When in the voltage detector mode the FD650/R employs the bar graph to
show the detected signal, and at the same time activates the buzzer. The
voltage detector function also has a built in test signal to check the
operation of its circuitry.
Other features of the FD650/R are Auto Power-down and Low Battery
Indication.
A three-position switch sets the FD650/R from OFF to either the Fuse
Finder or the Voltage Detector functions. A single push-button switch
controls all other operations of the FD650/R.

3.2 Description of Functions and Indicators
Auto Power Down:- The power down is activated after approximately 5
minutes without a valid signal. The power down mode can only be reset by
switching the unit OFF and then on again. In power down mode the typical
current drawn is 20μA.
The power down function can be deactivated by holding down the press
button when switching the unit on.
Buzzer:- An internal buzzer is used to inform the user when a signal has
been detected. In the fuse finder function the buzzer will continue to sound
even if the LED’s are not illuminated, provided that a signal is present.
Function Selection:- The required function is selected by sliding the three-
position slide switch from OFF to FIND (Fuse Finder) or VAC (Voltage
indicator).
1.1. LED’s:- There are two status LED’s on the LHS of the unit. The top
one is green and shows battery status. Continuous illumination means that
the battery level is acceptable. Flashing means that the battery should be
replaced.
1.2. The red LED is only used for the FIND function and indicates that the
unit is in automatic sensitivity mode.
8

A bar graph of 6 red LED’s on the RHS of the unit is used in both FIND and
VAC functions to display the signal strength.
1.3. Low Battery:- If the battery voltage is lower than a pre-set level of
6.9V the Green status LED flashes every 500ms. The battery should be
replaced (see section 4.1).
1.4. Push -button Switch:- Used to activate the following functions:-
1.5. Activation of test signal in VAC function.
1.6. Automatic threshold mode – in FIND function hold down push-button

3.3 Using the FD650/R and FD500/T or FD600/T as a
Fuse Finder
Ensure you have read the precautions (Section 3.1) before proceeding.
3.3.1 Pre-Check of the FD650/R and FD500/T or FD600/T
Plug the FD500/T or FD600/T transmitter into a known socket and ensure
the red ON indicator is illuminated.
Switch the FD650/R receiver to FIND and verify the green battery indicator
is continuously illuminated. If the green battery indicator is flashing the
battery is low and should be replaced (see section 4.1).
Hold the FD650/R in close proximity to the transmitter and verify
illumination of the FD650/R SIGNAL bar graph and that an audible tone is
present. The number of illuminated segments of the bar graph will depend
on the FD650/R position and orientation with respect to the transmitter.
Do not use if the pre-check fails.
3.3.2 Locating a Fuse or Circuit Breaker
Plug the FD500/T or FD600/T into a socket of the circuit to be traced and
ensure the red ON indicator is illuminated. If you are using the FD600/T
with TL83 or TL88 leads refer to section 3.3.5.
Switch the FD650/R to FIND and verify the green battery indicator is
continuously illuminated.
When switched to FIND, the FD650/R defaults to the manual threshold
mode (see section 3.3.3). The FD650/R can alternatively be operated in the
automatic threshold mode (see section 3.3.4).
N.B. The unit defaults to Manual Mode when switched on (see
sections 3.3.3 and 3.3.4).
10
3.3.3 Using in Manual Threshold Mode
Hold the FD650/R receiver in close proximity to the box suspected of
housing the fuse or circuit breaker being sought. If the signal is present an
audible tone will be emitted from the FD650/R.
Hold the FD650/R against the first fuse or circuit breaker of the box as
shown in figure 4. The orientation of the FD650/R in relation to the fuse /
breaker must be as shown in figure 4 and it should be held in the centre of
the fuse or circuit breaker.
Depending on the signal strength the bar graph may be activated. Press
the SET button to set the sensitivity and the lower 3 to 4 segments of the
bar graph will be illuminated.
Move along the row of fuses/circuit breakers, stopping at the centre of each
fuse/circuit breaker and noting the signal strength on the bar graph display.
Every time this signal causes the bar graph to exceed 3 to 4 segments,
press the SET button to set the new sensitivity threshold.
Be sure to check all the fuses/circuit breakers, and then go back over all
the fuses/circuit breakers. Only one fuse/circuit breaker should now show a
signal strength indication on the bar graph. If this is not the case then
repeat the above procedure, until only a single fuse/circuit breaker causes
an indication.
Switch off/remove the fuse/circuit breaker that shows the maximum signal
strength and check that the FD650/R bar graph is no longer illuminated and
the audible tone is no longer present when the fuse / circuit breaker
location is re-checked.
Go to the transmitter, if the correct fuse/circuit breaker has been switched
off/removed then the red ON indicator should no longer be illuminated.
11
Figure 4. Correct
The receiver must be held
in this orientation in relation
to the breaker to find the
correct fuse/circuit breaker.
If the individual breakers
were horizontal, the
receiver would have to
rotated through 90° (in
either direction).

3.3.4 Using in Automatic Threshold Mode
With the selector switch set to FIND, hold down the SET button for
approximately 2 seconds until the red MODE indicator is illuminated.
Hold the FD650/R receiver in close proximity to the box suspected of
housing the fuse, or circuit breaker, being sought. If the signal is present an
audible tone will be emitted from the FD650/R.
Hold the FD650/R against the first fuse or circuit breaker of the box as
shown in figure 4. The orientation of the FD650/R in relation to the fuse /
breaker must be as shown in figure 4 and it should be held in the centre of
the fuse or circuit breaker.
The FD650/R will automatically set the sensitivity threshold to show a
signal strength indication on the bar graph. The signal strength indication
on the bar graph may be centred to display 3 to 4 segments at any time by
pressing the SET button.
Be sure to check all the fuses/circuit breakers, and then go back over all
the fuses/circuit breakers maintaining uniform proximity during and after
each pass to prevent incorrect re-setting of the receiver sensitivity. Only
one fuse/circuit breaker should now show a signal strength indication on
the bar graph. If this is not the case then repeat the above procedure, until
only a single fuse/circuit breaker causes an indication.
Switch off/remove the fuse/circuit breaker that shows the maximum signal
strength and check that the FD650/R bar graph is no longer illuminated and
the audible tone is no longer present. Go to the transmitter, if the correct
fuse/circuit breaker has been switched off/removed then the red ON
indicator should no longer be illuminated.
3.3.5 Connecting the FD600/T using TL83 or TL88 Leads
If you are using the FD600/T with TL83 leads to trace wiring, connect the
black crocodile clip to neutral and red to live in that order and then plug the
TL83 lead into the FD600/T IEC inlet socket.
13
Optionally TL88 leads can also be used with the FD600/T. Connect the
black crocodile clip to neutral and red to live in that order and then plug the
TL88 lead into the FD600/T IEC inlet socket. The green crocodile clip
should be clipped to earth as a safety measure.

3.4 Using the FD650/R as a Voltage Detector
Ensure you have read the precautions (section 3.1) before proceeding.
3.4.1 Pre-Check of the FD650/R
Switch the FD650/R to VAC and verify the green battery indicator is
continuously illuminated. If the green battery indicator is flashing the battery
is low and should be replaced (see section 4.1).
Press the FD650/R TEST button and verify all the segments of the
FD650/R VAC bar graph are illuminated and an audible tone is present.
Do not use if the pre-check fails.
14
3.4.2 Locating Live Wiring/Cabling
Switch the FD650/R to VAC and verify the green battery indicator is
continuously illuminated.
Hold the tip of the FD650/R to the cabling to be tested. Where multi-core
cabling is being tested run the tip of the FD650/R along a short length of
the cable to overcome the electrical effects of the natural twist in the
conductors.
If the wiring/cabling is live the VAC bar graph will display an indication and
an audible tone will be emitted from the FD650/R.
4. MAINTENANCE
4.1 Battery Replacement
