The Peak Atlas DCA
A fresh approach to component analysis has resulted in the fantastic
Peak Atlas DCA, an intelligent, slim and invaluable tool. A world of detailed
component data has never been so accessible.
Just connect your component any way round and press the test button. The
Atlas DCA
will then present you with detailed component information in concise,
easy to read, scrollable pages. The displayed information will include:
the component type, special component features, component pinout, and
measured parameters (such as gain, leakage current, gate threshold
voltages, volt drops etc...). No more searching through data books and
catalogues in order to identify components and pinouts, the Atlas does
it all. |
|
Analysis Portfolio
It doesn't matter how you connect the test clips to the component, the
Atlas can analyse a vast number of different component types including
bipolar transistors, enhancement mode MOSFETs, depletion mode MOSFETs,
Junction FETs, low power thyristors and triacs (less than 5mA trigger
and hold), diodes, multiple diode networks, LEDs, bi-colour and
tri-colour LEDs. It will even identify special component features such
as diode protection and shunt resistors in transistors. For two-leaded
components such as diodes and LEDs, any pair of test clips can be
applied to the component any way round, the Atlas DCA sorts it all out
for you. |
|
|
|
|
Simplicity
There is no on/off switch, power is automatically turned on at the
start of an analysis and then automatically turned off if inactive for
more than 30 seconds. Each page of displayed information is presented
in manageable amounts, with each page being displayed when you want it.
If you want to concentrate on the "pinout" page then just select that
page, you don't have to see information that you don't need.
The Atlas DCA Package
The Peak Atlas DCA is supplied complete with a long life battery,
universal test probes and a comprehensive illustrated user guide.
Furthermore, free and unlimited technical support and advice is
available to all users by telephone, fax, email or our web site. |
