Analysing Components – Standalone Mode
The DCA Pro is designed to analyse discrete,
unconnected, unpowered components. This
ensures that external connections don’t
influence the measured parameters. The three
test probes can be connected to the component any
way round. If the component has only two terminals, then
any pair of the three test probes can be used.
The DCA Pro will start component analysis when the on-test button is
pressed.
For the first analysis (after the unit has
been switched off) the tests are
performed while displaying the Peak
logo.
For subsequent testing when the unit
is already powered-up, the unit
displays the “ Testing… ” screen.
Depending on the component type, analysis may take a few seconds to
complete, after which, the results of the analysis are displayed.
Information is displayed a “page” at a time, each page can be smoothly scrolled
by briefly pressing the scroll-off button.
Although the DCA Pro will switch itself off if left unattended, you
can manually switch the unit off by holding down the scroll-off
button for a couple of seconds.
