Measurement Procedure
1. Press the ON/OFF key to turn the meter on.
Note: For best result perform your tests between 20-24 °C (68-75.2 °F).
9. Insert the second cuvette with the reacted sample into the holder and
ensure that the notch on the cap is positioned securely in the groove. Press
READ /TIMER. The lamp, cuvette and detector icons will appear on the
display, depending on the measurement phase.
2. A short beep alert together with four-dash lines displayed on the main LCD
indicate that the meter is ready. The “ZERO” message displayed blinking
indicates that the meter is ready for zeroing.
During Calibration
Standard low: The standard reading is less than
expected.
Standard high: The standard reading is higher than
expected.
10. At the end of measurement, the instrument directly displays concentration in
µg/L of manganese on the LCD.
3. Fill one cuvette with 10 mL of deionized water and a second cuvette with 10 mL
of sample.
4. Add one packet of HI93748A-0 Ascorbic acid to each cuvette, replace the
plastic stopper and the cap. Shake gently until the Ascorbic acid dissolves.
Note: 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.

5. Add 0.2 mL of the HI93748B-0 Alkaline-cyanide reagent solution to each
cuvette, replace the plastic stopper and the cap. Invert gently to mix for about
30 seconds.
Interference may be caused by: 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.

7. 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.
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.
3’’
or

Cap error: Message is displayed when external light
enters in the analysis cell. Ensure that the cuvette cap is
in place.
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.
Cooling lamp: The instrument waits for the lamp to cool
down.
Low battery: Battery indicator is displayed empty. The
battery must be replaced soon.
Dead battery: This indicates that the battery is dead
and must be replaced. Change the battery and restart the
meter.
GLP
In GLP mode, the last calibration date can be verified and the factory calibration
can be restored.
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.
Last Calibration Date
1. Press GLP/ to enter GLP mode. The calibration month and day will appear
on the main display and the year on the secondary display.
No light: The instrument cannot adjust the light level.
Please check that the sample does not contain any debris.
Sample Reading
8. Press and hold READ /TIMER for three seconds. The display will show the
countdown prior to zeroing the blank. Alternatively, wait for 2 minutes and then
press ZERO/CFM and the lamp, cuvette and detector icons will appear on the
display, depending on the measurement phase. After a few seconds the display
will show “-0.0-”. The meter is now zeroed and ready for measurement.
Remove the cuvette.
Other Errors & Warnings
“donE” message to indicate that factory calibration has been restored and
then returns to measurement mode.
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.
Reagent Sets
Inverted cuvettes: The sample and the zero cuvette are
inverted.
Zero: A zero reading was not 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.
Accessories
Restoring Factory Calibration
1. Press GLP/
to enter GLP mode.
2. Press READ /TIMER to enter restore factory calibration screen. The
instrument asks for confirmation to delete user calibration.
3. Press ZERO/CFM to restore the factory calibration (or press GLP/ again
to exit without restoring factory calibration). The meter briefly displays
