LOG-ON-DEMAND:
• After taking a read-
ing, press the STO
button. The last
sample read will be
stored in memory.
The display will also
show on the bottom
right corner the reference number of the
stored sample.

has been reached
(199), the LCD dis-

numbers reduced by one). Sample number
one remains the oldest sample.

gether. The display
will show "CLR" for

ENSURE ACCURATE MEASUREMENTS
• Each time the cuvet is used, tighten the cap
to the same degree.
• Discard the sample soon after the reading is
taken to avoid permanently clouding the glass.
• All glassware used to contain the standards
and the samples should be maintained clean,
washed with the HI 93703-50 cleaning solution
and rinsed with HI 93703-0 or turbidity-free
water.
• Collect the samples in clean glass or plastic
bottles, fit stoppers and perform the analysis
quickly. If necessary, store the sample in a
cool, dark place, for up to a maximum of 24
