Things to try
Way out for user
E02
Blanking timed out.
Sample ran out. Noisy
signal due to sample.
Noisy signal due to
instrument malfunction.
Check there is plenty of
sample. Verify nebuliser
uptake rate.
E02 is displayed for 5s,
then automatically returns
to start of blanking. No
output sent.
E05
Blank signal outside
offset range.
Blank contaminated.
Check with fresh blank.
Re-start Blank.
E 06
Detector circuit
saturated in Blank.
Gross contamination of
blank; Blank not being
used.
Check with fresh blank.
Re-start Blank.
E09
Blank out of limits.
(E09 is displayed on
the offending
channel(s) and the
appropriate element
symbol(s) will flash).
There are arbitrary
ceilings for blank signals
on each element.
Sample was not a blank.
Signal was too noisy.
Li in blank when it
shouldn't have been.
Try a guaranteed blank.
Check the nebuliser.
E09 is displayed for 5s,
then automatically returns
to start of blanking. Make
sure a blank sample is
being aspirated and press
"Blank". Output will also
indicate error by showing
"----" for measurement
value(s).
E12
Peak cycle timed out
during calibration.
Sample ran out. Noisy
signal due to sample.
Noisy signal due to
instrument malfunction.
Check there is plenty of
sample. Verify nebuliser
uptake rate.
E12 is displayed for 5s,
then automatically returns
to start of calibrate
(does not go back to
beginning of blanking). No
output sent.
E15
Calibration Invalid.
Reading/Calibration
Factor >99.
Check concentration of
Standard has it been
diluted correctly.
Start Calibration sequence
again.
E16
Detector circuit
saturated in Calibrate.
Gross error in Standard
concentration; Standard
not diluted.
Check concentration of
Standard has it been
diluted correctly.
Start Calibration sequence
again.
E19
Standard reading over-
range.
(In calibrate only).
There are arbitrary
ceilings for signals on
each element. Wrong
value Standard. Signal
was too noisy. Li in
Standard when it
shouldn't have been.
Check concentration of
standard. Increase
sample dilution.
In CONT. E19 is displayed
until something causes
reading to come back in
range. In PEAK E19 is
displayed until cancelled
by introduction of new
standard and press of
'Set'.
E22
Peak timed out during
measure.
Sample ran out. Noisy
signal due to sample.
Noisy signal due to
instrument malfunction.
Check there is plenty of
sample. Verify nebuliser
uptake rate.
Press 'Print' in usual way.
(To repeat without
changing sample number
press and hold 'Print')
Output will also indicate
error by showing "----" for
measurement value(s).
E25
Sample > 125% of top
standard.
Sample not diluted
correctly. Very abnormal
sample; incorrect
standard used for
sample.
Check correct standard;
check dilution, if
necessary increase
dilution ratio.
In CONT. message will
disappear when sample
removed; in PEAK
introduce new sample and
press Print.
