SuperBroom Plus TA – Operating Manual

NVIRONMENTAL

CONDITIONS

The Super Broom has been designed to operate within the

following conditions:

Temperature conditions of +5°C to +35°C (The LCD may

slow down at +5°C.)

OWER

EQUIREMENTS

SuperBroom only operates powered by its internal battery

pack. The external AC/DC Adaptor is used to recharge

the battery only and cannot be used to directly power

SuperBroom.

ATTERY

The internal rechargeable Lithium Ion battery pack gives

3-20 hours continuous use (dependent on the power output

setting). The battery will need to be recharged when the front

panel LCD display shows approximately 6.5 V. The battery

is automatically recharged when external power is applied

to the SuperBroom via the external AC/DC Adaptor. Internal

protection circuitry protects the battery. If for any reason

the battery suffers any transient fault such as short-circuit,

overcharging or deep discharge, the pack will shutdown. It

will remain in this state until recharged by connection of the

external AC/DC Adaptor.

If the SuperBroom is left switched on, as the battery power

level falls, the following sequence of events will eventually

occur:

1 SuperBroom enters a reset state, this is indicated by

all 6 LEDs on the left-hand side of the front panel

illuminating.

2 The battery pack protection circuitry will shut down

the battery pack. All signs of life will be absent.

THEORY OF OPERATION - HARMONIC RADAR

This section is intended to explain how SuperBroom

detects electronic devices and why it has two receivers.

Understanding this theory is not essential to operation of

SuperBroom but should help users perform a faster sweep

and be more appreciative of operation.

RINCIPLE

PERATION

SuperBroom detects electronic Components that are:

Diodes

or Transistors

or Integrated Circuits

These components are used to make electronic devices

(together with other components such as resistors and

capacitors, for example). SuperBroom can detect electronic

devices regardless of whether the device is powered or

operational although this may affect how well it can be

detected from a given distance.

SuperBroom does not react to resistors, capacitors,

transformers, batteries and other components that do not

contain diode- or transistor-like materials.

SuperBroom does not detect metal objects except when

metallic semi-conducting junctions are formed - this is

explained below.

LINEAR

UNCTION

Distortion of a signal results in generation of harmonics of

the incident signal. Higher frequencies are produced which

are a whole number multiples (integer multiples) - termed

'harmonics' - of the incident signal.
