Self Test Procedure
Each time the
SCR100
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 unit will switch off automatically.
If the problem was caused by a
temporary condition, such as applying
power to the test clips, then simply
restarting the
SCR100
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 or a
large static discharge taking place. 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 may not be performed.
