6.0 Troubleshooting
The instrument routinely performs self-diagnostics, and will automatically generate
messages to provide specific diagnostic information.
6.1
System Warning Messages
Automatic warning messages are generated to provide specific diagnostic information
about the instrument. These messages are for the operator’s use and do not indicate a
reduction in the performance of the instrument or a failure of any component in the
instrument.
6.2
Battery Low Indicator
There are two battery warning levels. A flashing battery icon on the display indicates that
the batteries need to be replaced, but the readings displayed are still accurate. This is a
warning that the batteries are low.
A solid battery icon on the display indicates that power level is too low and the readings may be
out of specification. Under this condition, the batteries should be replaced as soon as possible to
ensure that the instrument will continue to function properly. If the batteries get too low to
perform, the instrument will turn off & the instrument may not turn on until the batteries have
been replaced. See section 6.2 for more information
