Resetting the Model 241CE II Analyzer
Whenever the analyzer is powered up, the Microcontroller board is reset
and the software initialization routine retrieves the configuration data
from the EEPROM. When power is restored following a power outage or
brown-out (line voltage drops to less than two-thirds of the nominal volt-
age), the Microcontroller board will be reset and the analyzer will become
operational automatically.
The analyzer can be reset by pressing the and ‘–’ buttons simultane-
ously while viewing the Main Menu (RUN menu). Alternatively, power to
the analyzer can be turned Off and then On again using the main breaker.
Do not randomly reset the analyzer during normal operation. Typical-
ly, the only resets required are after changes to the 7 have been saved
to the EEPROM or if the Microcontroller board has been replaced.
If changes to the configuration have been saved to the EEPROM, a
reset is necessary for the new changes to take effect. If the Microcon-
troller board has been replaced, it is necessary to power down the
analyzer. The analyzer will reset upon normal power-up.
