Self Test Procedure

Each time the DCA Pro is powered up, a self test procedure is performed. In
addition to a battery voltage test, the unit measures the performance of many
internal functions such as the voltage and current sources, amplifiers, analogue
to digital converters and test lead multiplexers. If any of these function
measurements fall outside tight performance limits, a message will be
displayed and the instrument will switch off automatically.
If the problem was caused by a
temporary condition on the test clips,
such as applying power to the test clips,
then simply re-starting the unit may
clear the problem.
If a persistent problem does arise, it is likely that damage has been caused by
an external event such as excessive power being applied to the test clips. If the
problem persists, please contact us for further advice, quoting the displayed
fault code.
If there is a low battery condition, the automatic self test procedure
will not be performed. For this reason, it is highly recommended that
the battery is replaced as soon as possible following a low battery
warning.
