General Description & Intended Use
HI96742 portable photometer is designed to measure low range iron and
manganese in applications such as water quality control checks.
It features an advanced combination of a special tungsten lamp, narrow band
interference filter and silicon photodetector to ensure accurate photometric readings.
The Hanna exclusive CAL Check™ feature utilizes NIST traceable standards to verify
meter validation and calibration.

3. For Iron LR: Fill a graduated mixing cylinder up to the 25 mL mark with
deionized water. Add the content of one packet of HI93746-0 reagent, close
the cylinder and shake well for 30 seconds. This is the blank. Fill a cuvette
with 10 mL of the blank (up to the mark) and replace the plastic stopper and
the cap.
11. Add one packet of HI93748A-0 Ascorbic acid to each cuvette, replace
the caps and shake gently until complete dissolution. Add 0.2 mL of the
HI93748B-0 Alkaline-cyanide reagent solution to each cuvette, replace
the caps and invert gently to mix for about 30 seconds. Add 1 mL of the
HI93748C-0 0.1% PAN indicator solution to each cuvette, replace the plastic
stopper and the cap. Shake gently.

12. Insert the cuvette with the reacted deionized water (blank) into the holder and
ensure that the notch on the cap is positioned securely in the groove.
No light: The instrument cannot adjust the light level. Please
check that the sample does not contain any debris.
Inverted cuvettes: The sample and the zero cuvette are
inverted.
Zero: Zero reading has not been taken. Follow the instructions
of the measurement procedure for zeroing the meter.
Under range: A blinking “0” indicates that the sample
absorbs less light than the zero reference. Check the procedure
and make sure you use the same cuvette for reference (zero)
and measurement.
Over range: A flashing value of the maximum concentration
indicates an over range condition. The concentration of the
sample is beyond the programmed range: dilute the sample
and re-run the test.

Other Errors & Warnings
Cap error: Message is displayed when external light enters
in the analysis cell. Ensure that the cuvette cap is in place.
Cooling lamp: The instrument waits for the lamp to cool
down.
15. Depending on the selected parameter, the instrument directly displays the
concentration in mg/L of iron or in µg/L of manganese.
Low battery: Battery indicator is displayed empty and
blinking. The battery must be replaced soon.
Note: For Manganese LR a temperature above 30 °C may cause turbidity. In
this case, before zeroing and taking readings, add 2-3 drops of Dispersing agent
(HI93703-51) to each cuvette and swirl until complete dissolution of turbidity.
Dead battery: This indicates that the battery is dead and
must be replaced. Change the battery and restart the meter.
Interferences
• Iron LR: Cadmium above 4.0 mg/L, Chromium6+ above 1.2 mg/L, Copper above
0.6 mg/L, Manganese above 50.0 mg/L, Molybdenum above 4.0 mg/L, Nitrite ion
above 0.8 mg/L, Chromium3+ above 0.25 mg/L, Cobalt above 0.05 mg/L, Cyanide
above 2.8 mg/L, Mercury above 0.4 mg/L, Nickel above 1.0 mg/L. Sample pH
should be between 3 and 4 to avoid developed color to fade or turbidity formation.
• Manganese LR: Aluminum above 20 mg/L, Cadmium above 10 mg/L, Calcium
above 200 mg/L as CaCO3, Cobalt above 20 mg/L, Copper above 50 mg/L, Iron
above 10 mg/L, Lead above 0.5 mg/L, Magnesium above 100 mg/L as CaCO3,
Nickel above 40 mg/L, Zinc above 15 mg/L.
GLP
In GLP mode, the last calibration date can be verified and the factory calibration
can be restored.
Last Calibration Date
1. Press and hold RANGE/GLP for three seconds to enter GLP mode. The
calibration month and day will appear on the main display and the year on
the secondary display.
Error & Warning Messages
Zero Reading
Light high: There is too much light to perform a measurement.
Please check the preparation of the zero cuvette.
Light low: There is not enough light to perform a
measurement. Please check the preparation of the zero cuvette.
1. Press and hold RANGE/GLP key for three seconds to enter GLP mode.
2. Press READ /TIMER key to enter restore factory calibration screen. The

Restoring Factory Calibration
2. If no calibration was performed, the factory calibration message, “F.CAL” will
appear on the main display and the instrument returns to measurement mode
after three seconds.

3. Press ZERO/CFM key to restore the factory calibration (or press
RANGE/GLP key again to exit without restoring factory calibration). The
meter briefly displays “donE” message to indicate that factory calibration has
been restored and then returns to measurement mode.
Battery Management
To save the battery, the instrument shuts down after 10 minutes of non-use in
measurement mode and after 1 hour of non-use in calibration mode.
If a valid measurement value was displayed before
auto shut off, the value will then be displayed when the
instrument is switched on. The blinking “ZERO” means
that a new zero has to be performed.
One fresh battery lasts about 750 measurements, depending on the light level.
The remaining battery capacity is evaluated at startup and after each measurement.
The instrument displays a three-levels battery indicator:
• 3 lines indicate 100 % capacity
• 2 lines indicate 66 % capacity
• 1 line indicate 33 % capacity
Battery indicator is displayed blinking if the capacity is under 10 %.
If the battery is empty, the meter displays “dEAd bAtt” message and turns off.
To change the battery:
1. Press the ON/OFF key to turn the instrument off.
2. Turn the instrument upside down and turn
the battery cover located on the back of
the meter counterclockwise to unlock.
3. Remove the cover and replace the
battery.
4. Insert back the battery cover and turn it
clockwise to close.
