• Alkalinity above 250 mg/L CaCO3 or acidity
above 150 mg/L CaCO3 will not reliably
develop the full amount of color or it may
rapidlyfade.
To resolve this, neutralize the sample with
diluted HCl or NaOH.
• In case of water with hardness greater
than 500 mg/L CaCO3, shake the sample
for approximately 2’ after adding the reagent.
GUIDE TO DISPLAY CODES:
This prompt appears for 1
second each time the
instrument is turned on.
The dashes “- - -” indicates
that the meter is in a ready
state and zeroing can be
performed.
Sampling In Progress.
Flashing “SIP” prompt
appears each time
the meter is performing a measurement.
“-0.0-”, the meter is in
a zeroed state and
measurement can beperformed.
The blinking “BAT” indicates
that battery voltage is
getting low and the battery
needs to be replaced.
“-bA-”, the battery is dead and
must be replaced. Once
this indication is displayed,
the meter will lock up.
Change the battery and restart the meter.
“Conf”, the meter has lost
its configuration. Contact
your dealer or the nearest
Martini Customer Service Center.
ERROR MESSAGES
On zero reading
• Blinking “-0.0-” indicates
that the zeroing procedure
failed due to a low signal-
to-noise ratio. In this case
press ZERO again.
• “no L”, the instrument
cannot adjust the light level.
Please check that the sample
does not contain any debris.
• “L Lo”, there is not enough light
to perform a measurement.
Please check the prepara-
tion of the zerocuvet.
• “L Hi”, there is too much
light to perform a measure-
ment. Please check the
preparation of the zero cuvet.
On sample reading
• “-SA-”, there is too much
light for the sample
measurement. Please
check if the right sample
cuvet is inserted.
• “Inv”, the sample and
the zerocuvet are inverted.
• “ZErO”, a zero reading was
not taken. Follow the instruc-
tion in the measurement
procedure for zeroing the
meter.
• Under range. A blinking “0.00”
indicates that the sample
absorbs less light than the
zero reference. Check the
procedure and make sure you
use the same cuvet for reference
(zero) and measurement.
• A flashing value of the
maximum concentration
indicates an over range
condition. The concent-
ration of the sample is
beyond the programmed
range: dilute the sample
and re-run the test.
BATTERY REPLACEMENT
Battery replacement
must only take place
in a
non-hazardous
environment.
Simply rotate the
battery cover on the
back of
the meter.
Detach the battery from
the terminals and
attach a fresh 9V
battery while paying
attention to the correct polarity.
Insert the battery and replace the cover.
