Error Codes
See also Section 3.1 and 3.2 of the Instruction Manual
A number of Error Codes are generated that relate to various fault
conditions, these are detailed below with a brief description of
some of the most common causes for these errors.
Err 1
, Dark level too high during a functional calibration. In
normal operation the dark shutter closes during an operator
instigated calibration sequence to ensure that the detector output is
below a threshold level. The calibration is aborted and Err 1
indicated if the detector output is above this threshold level. The
most likely cause is that the sample chamber door has been left
open or was opened during the calibration sequence, it may also
occur due to a faulty detector PCB.
Err 2
, Light level too low during a functional calibration. This may
be caused by the sample/calibrant being too optically dense (dark),
it may also be caused by lamp failure as well as the use of plastic
or glass cuvettes at wavelengths where these materials will absorb
a high proportion of the light energy.
Err 3
, Standard out of range in a concentration measurement. This
may be because the standard is too optically dense at the
wavelength selected or it may be too similar to the blank. Dillution
of the sample may be applicable for the former or the wavelength
for the later method may require adjustment.
Err 4
, No zero order (white) light found during wavelength
calibration in start up routine. This error is given at the end of the
wavelength calibration routine, indicating that the test was partly
successful (see Section 6.1 Start Up Routine). Hence this error is
normally caused by low energy levels due to lamp ageing or
contamination/deterioration of other optical components. Also
ensure that a sample or cuvette has not been left in the sample
chamber during the start up tests and that there is no splashing or
spillage on the exit and detector lenses.
Err 5
, No zero order (white) light found during wavelength
calibration in start up routine. This error is given during the
wavelength calibration routine, indicating that even the initial
threshold level was not achieved. Possible causes are; incorrect
