7.2. System Error Message(s)
The instrument generates error messages when problems are detected during normal operation.
When these messages are observed and if you do not understand the instructions shown below,
contact the HF scientific Technical Services department to determine a resolution to the problem.
The instrument indicates an error message when an "E-XX" is displayed on the lower row of the
display.
The instrument has several error codes, each assessing a different component or system of
components in the instrument. The following table lists the error messages and their associated
meanings.
ERROR ASSOCIATED MEANING TYPICAL CAUSE
E-01 The A/D has failed to report
correctly One or several components in the A/D circuit
has failed … call technical service
immediately
SFE General Electronics Failure One or many electrical components have
failed in the instrument.
If an error is noted, please contact the HF scientific Technical Services Department immediately to
rectify the error.
7.3. Factory Default Parameters
The instrument retains all original factory settings in non-volatile memory. At any time, you can
cause the instrument to change back to these default settings. This is particularly useful if you feel
that your calibration standards may have been compromised or if someone has erred in their use of
the instrument. In these situations you may use the factory default parameters while waiting for new
standards (or instructions) to arrive from HF scientific, inc.
To invoke this option, turn the instrument on and then press the S key while holding down the ◄
key. The instrument will perform several operations (taking approximately 2 minutes) and then turn
off indicating that the memory and all settings have been reset to the factory default parameters.
After this point you may start to use the instrument again as you normally would.
8. Routine Maintenance
The instrument has been designed for ease of use and simple operation. When not in use, ensure that
the instrument has been turned off and that a clean sample cuvette fitted with a black light shield cap
has been placed in the sample well. This will ensure that a minimal amount of dust and/or debris
will be able to settle on the optics of the instrument.
