LCD Message Description Corrective Action
HI In READ mode: test sample concentration is above the
measurement range (test specifi c).
Dilute and retest. Dilution kit available
(Part No. 487200)
LO In READ mode: test sample concentration is below the
measurement range (test specifi c).
Sample value is below
measurement range.
LO In ZERO mode: sample absorbency (due to a cloudy
or colored sample or a dirty cell) is too high to zero, the
meter will read “LO” or low battery
Dilute sample, fi lter sample or clean
cell. One of these options should
remedy the problem. You may need
to replace batteries if low battery
indication.
ER Excessive stray light detected. Normally this does not
occur, even when testing in sunlight.
Place the light blocking CAP over the
CELL for zeroing and for reading result.
Moving to a shaded can also fi x
this problem.
Low battery indication during testing
(meter may not zero)
Replace batteries immediately. Otherwise
meter may read LO while testing.
