EEPROM SELFTEST
The EEPROM selftest procedure involves verifying the stored
EEPROM checksum.
• To enter the EEPROM test procedure select the setup item
t.02 and an “OFF” blinking message will appear on the
LCD.
• Press the  (or ) key once and the message will switch to
a blinking “GO”.
• Press CFM key to confirm or the  (or ) key again to
return to the previous status.
• If confirmation is given when the “OFF” message is blink-
ing, no action is performed and it will move to the next
setup item (t.03).
• After confirmation, the selftest
procedure begins with the “tESt”
message blinking for a few sec-
onds.
• During this time the instrument performs the EEPROM check,
and if the checksum is correct, the “Stored data good”
message will scroll on the primary display.
• After that, the meter will remain in setup menu and move to
the next setup item.
• If the checksum fails, a fault alarm is generated and the
following message appears on the LCD: “Stored data error
- Press “UP” button to reset stored data or “RIGHT” button
to ignore”.
• If the  key is pressed the instrument restarts operation,
but the device will be in Hold mode in any case (i.e. no
acquisition of measurements).
• If the  key is pressed, all the data stored in the EEPROM
are erased and the default values loaded (a complete cali-
bration of the instrument is needed).
• Once performed the selected action, the instrument will
remain in the setup menu and move to the next setup item
(t.03).
