INSTRUCTIONS
SAFETY INFORMATION: Always read before proceeding.
WARNING
These instructions contain both information and warnings that are
necessary for the safe operation and maintenance of the FD650/R and
FD500/T or FD600/T. It is recommended that you read the instructions
carefully and ensure that the contents are fully understood. Failure to
understand the instructions and to comply with the warnings and
instructions contained herein can result in serious injury, damage or
even death.
In order to avoid the danger of electrical shock, it is important that
proper safety measures are taken when working with voltages
exceeding 30 V AC rms, 42 V AC peak or 60 V DC.
The FD650/R and FD500/T FD600/T must only be used under the
conditions and for the purposes for which they have been
constructed. Particular attention should be paid to the safety
instructions, the technical specifications and the use of the FD650/R
and FD500/T or FD600/T in dry surroundings.
Always check the FD650/R and FD500/T or FD600/T are in good
working order before use and that there are no signs of damage to
any unit. Do not use if damaged.
Keep these instructions for future reference. Updated instructions

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.
