7.1.2 - Other signs:
Error
Reason
Action
E1 - E1
E2 - E2
E3 - E3
The relative probe may
be broken (E) or
shorted (-E), or it may
have a value that is
outside the
programmed range.
Check the connection of
the probe with the
device and verify the
correct functioning of
the probe. (it is useful to
have the ohm values of
the probes)
EP
Possible anomaly in the
EEPROM memory
Press the SET key.
Turn the device off and
on
Err
Fatal Device Memory
Error
Replace the device or
send it in for possible
repair
7.2 - CLEANING
It is recommended to clean the B4U only with a cloth slightly
dampened with water or a non-abrasive detergent and that does not
contain solvents.
7.3 - WARRANTY AND REPAIRS
