Data error
In certain operating conditions, the instrument may detect errors in the data saved. These errors may compromise the
correct operation of the instrument. If the microprocessor detects a data saving error, the display shows the message
“EE”. If the fault persists, the controller needs to be replaced. If, on the other hand, the message disappears, it can con-
tinue to be used. When “EE” error occurs frequently and/or remains for some time, the controller should be checked,
as the original precision may not be guaranteed.
