SETTING RESTORE
The settings are stored in a nonvolatile EEPROM memory. If a
power failure appears the settings are restored after power on.
When power is first time applied to PCA 310-330 analyzers,
the settings are set to factory default values.
At startup the EEPROM content is analyzed and, if some set-
tings are corrupted, a restore procedure is started. The instru-
ment displays the following screen:
Press “CFM” to restore the settings that are out of range. In
this case, the corrupted settings are set to default. In this case
all settings should be checked in to see the values.
Press “SET” to restore to default of all settings.
In extreme situation when the LCD is blank at startup, is pos-
sible to reset the instrument by keeping the keys “UP” + “SET”
+ “MENU” pressed while the instrument is powered on.
