Important Considerations
Please observe the following guidelines:
•
This instrument must NEVER be connected to powered
equipment/components or equipment/components with any
stored energy (e.g. charged capacitors). Failure to comply
with this warning may result in personal injury, damage to
the equipment under test, damage to the
Atlas DCA
and
invalidation of the manufacturer’s warranty.
•
The
Atlas DCA
is designed to analyse semiconductors that
are not in-circuit, otherwise complex circuit effects will
result in erroneous measurements.
•
Avoid rough treatment or hard knocks.
•
This unit is not waterproof.
•
Only use a good quality Alkaline battery.

Darlington transistors can have very

gain will be evident as a result of this.
Additionally, it is quite normal for transistors of the same type to have a wide
range of gain values. For this reason, transistor circuits are often designed so
that their operation has little dependence on the absolute value of current gain.
The displayed value of gain is very useful however for comparing transistors of
a similar type for the purposes of gain matching or fault finding.

WEEE (Waste of Electrical and Electronic Equipment),
Recycling of Electrical and Electronic Products
United Kingdom
In 2006 the European Union introduced regulations (WEEE) for the collection
and recycling of all waste electrical and electronic equipment. It is no longer
permissible to simply throw away electrical and electronic equipment. Instead,
these products must enter the recycling process.
Each individual EU member state has implemented the WEEE regulations into
national law in slightly different ways. Please follow your national law when
you want to dispose of any electrical or electronic products.
More details can be obtained from your national WEEE recycling agency.
If in doubt, you may send your Peak Product to us for safe and environmentally
responsible disposal.
At Peak Electronic Design Ltd we are committed to continual product development and improvement.
The specifications of our products are therefore subject to change without notice.
