5.0 Troubleshooting
The instrument routinely performs self-diagnostics, and will automatically generate
messages to provide you with specific diagnostic information.
5.1 System Warning Messages
Automatic warning messages are generated to provide you with specific diagnostic
information about the instrument. These messages are for your use and do not indicate a
reduction in the performance of the instrument or a failure of any component in the
instrument.
Battery Symbol: A battery on the display indicates that the batteries need to be replaced.
Under this condition, you should replace the batteries as soon as possible to ensure that
the instrument will continue to function properly. A flashing battery symbol indicates that
the batteries will fail very shortly. If the batteries get too low to accurately measure, the
instrument will turn off. The instrument might not turn back on until the batteries have
been replaced. See section 6.2 for more information
5.2 System Error Messages
There are two conditions for errors if the ERR icon is lit after turning the instrument on,
the onboard diagnostics have determined that there is a system error. Call HF Technical
Services for assistance as shown below.
If the case is the large word Err, the problem is usually due to an improper zero. Turn the
instrument off and repeat the three steps outline in section 3.0.
If the reading displays a flashing 10.0, the reading is over the measurement range of this
instrument.
