Resetting the automatic circuit breaker
The spectrometer has an automatic circuit breaker which prevents the system
from drawing too much current.
When the circuit breaker is activated, the switch flips to the off position
(marked ). This can happen while an analysis is running.
To reset the switch, wait a few seconds then put the switch to the on position
(marked ).
If this switch is activated frequently, contact your local PerkinElmer office for
advice.
