Dear Customer,
Thank you for choosing a Hanna product. This manual will
provide you with the necessary information for the correct
operation of the meter. Please read it carefully before using
the meter. If you need additional technical information, do
not hesitate to e-mail us at tech@hannainst.com.

EN 50081-1 and EN 50082-1.
PRELIMINARY EXAMINATION
Remove the instrument from the packing material and
examine it carefully to make sure that no damage has
occurred during shipment. If there is any damage, notify
your Dealer.
Each Ion Specific Meter is supplied complete with
• 9V Battery
• Two Sample Cuvets and Caps
• One Transport Cap
Note: Conserve all packing material until the instrument
has been observed to function correctly. Any defective
item must be returned in its original packing.
GENERAL DESCRIPTION
The HI 93702 meter measures the copper content in water
and wastewater in the 0.00 to 5.00 mg/L (ppm) range.
The meter uses an exclusive positive-locking system to ensure
that the cuvet is in the same place every time it is placed
into the measurement cell.
The reagents are in powder form and are supplied in
packets. The amount of reagent is precisely dosed to ensure
maximum repeatability.
Display codes aid the user in routine operations.
The meters have an auto-shut off feature that will turn the
instrument off after 10 minutes of non-use.

DISPLAY CODE GUIDE
This indicates that the meter is in a
ready state and zeroing can be performed.
Sampling in Progress. This prompt appears each time the meter is performing
a measurement.
This indicates that the meter is in a
zeroed state and measurement can be
performed.
A zero reading was not taken. Insert a
sample before adding reagent and press
ZERO.
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.
Over range. A flashing value higher than
the maximum concentration readable (see
specifications) indicates that the sample
absorbs too much light, meaning that
the concentration is too high. Dilute the
sample.
Light over range. The cuvet is not inserted correctly and an excess ambient
light is reaching the detector. If the cover
is properly installed, then contact your
dealer or the nearest Hanna Customer
Service Center.
Light under range. The zero sample is
too dark for proper zeroing. If this is not
the case, contact your dealer or the
nearest Hanna Customer Service Center.
V
The "V" indicates that the battery voltage is getting low and the battery needs
to be replaced.
This indicates that the battery is dead
and must be replaced.
Note: once this indication is displayed,
the meter will lockup. Change the battery to restart.
OPERATIONAL GUIDE
E
• Turn the meter on by pressing ON/OFF.
• When the LCD displays “- - -”, it is
ready.
• Fill the cuvet up to 1.5 cm (¾”)
below the rim with 10 mL of unreacted sample, and replace the cap.
• Place the cuvet into the holder
and ensure that the notch on
the cap is positioned securely
into the groove.
• Press ZERO and “SIP” will appear on the display.
ZERO
• Wait for a few seconds and the display will show “-0.0-”. Now the meter
is zeroed and ready for measurement.
• Remove the cuvet.
• Add the content of one packet
of HI 93702 reagent. Replace
the cap and shake gently.
• Reinsert the cuvet into the
instrument.

ON
• Press READ TIMED and the display will show the countdown prior to the measurement, or, alternatively wait
for 45 seconds and press READ DIRECT. In both cases
“SIP” will appear during measurement.

INTERFERENCES
Interference may be caused by:
Silver
Cyanide
For samples overcoming buffering capacity of reagent (around
pH 6.8), pH should be adjusted between 6 and 8.
TIPS FOR AN ACCURATE
MEASUREMENT
The instruction listed below should be carefully followed
during testing to ensure best accuracy.
• Do not touch the cuvet walls with hands.
• In order to maintain the same conditions during the
zeroing and the measuring phases, it is necessary to
close the cuvet to prevent any contamination.
• Do not let the test sample stand too long after reagent
is added or accuracy will be lost.
• Whenever the cuvet is placed into the measurement cell,
it must be completely free of fingerprints, oil or dirt.
Wipe it thoroughly with HI 731318 or a lint-free cloth
prior to insertion.
• It is important that the sample does not contain any
debris. This would corrupt the readings.
• It is possible to take multiple readings in a row, but it
is recommended that a zero reading be taken for each
sample and that the same cuvet is used for zeroing and
measurement.
• It is important to discard the sample immediately after
the reading is taken because the glass might become
permanently stained.
• Shaking the cuvet can generate bubbles in the sample,
causing higher readings. To obtain accurate measurements, remove such bubbles by swirling or by gently
tapping the vial.
• All the reaction times reported in this manual are
referred to 20°C (68°F). As a general rule of thumb,
they should be doubled at 10°C (50°F) and halved at
30°C (86°F).
BATTERY REPLACEMENT
Battery replacement must only take place in a non-hazardous area using a 9V alkaline battery.
Simply slide off 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.
Replace the battery and the cover.
