Troubleshooting/Errors
5004 Signals not increasing
The calibration has failed. The signal readings of the calibration standard solutions
are not increasing in the expected order. The instrument cannot calibrate using
this sequence of standards.
Suggested actions:
Move the cursor to the last standard measured and press Enter to clear the field
and remove the invalid concentration from the calibration. If more than one
standard has been measured the calibration should now be valid, indicated by the
symbol Cal in the bottom right of the display screen area.
Alternatively, remeasure the previous standard (ensuring you are using the correct
standard) by returning the cursor to the appropriate field and press Read.
5005 Slope test failure
The calibration has failed. The slope of the calibration curve changes too much
between successive standard signal readings.
5006 Calibration fit failure
The calibration has failed. A calibration curve could not be fitted to the measured
standards. Effective calibration is indicated by the symbol Cal in the bottom right
of the display screen area.
5008 Reslope signal out of range
Reslope calibration has failed. The reslope standard signal reading differed from
the original value by more than 25%.).
6000 Check HC lamp selection
This message is for information only. It is intended as a prompt for the operator to
ensure that the lamp selection lever is in the position consistent with both the
selected method element and lamp current.
9159 EEPROM checksum zero wl
The instrument will take several minutes to start up but will have no effect on
operation. If the error persists, a service call may be required.
