Errors and warnings:

ON 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.
No Light: The instrument cannot adjust the
light level. Please check that the sample does
key: press to enter GLP mode . In calibration mode press to not contain any debris.
ON SAMPLE READING:
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 "0.000" 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.
DURING CALIBRATION PROCEDURE:
Standard Low: The standard reading is less
than expected.
Standard High: The standard reading is higher
than expected.
OTHER ERRORS AND WARNINGS:
Cap error: Appears when external light enters
in the analysis cell. Assure that the cuvette cap
is present.
Cooling lamp: The instrument waits for the
lamp to cool down.
Battery low: The battery must be replaced soon.
Dead battery: This indicates that the battery
is dead and must be replaced. Once this
indication is displayed, normal operation of the
instrument will be interrupted. Change the
battery and restart the meter.

Measurement procedure:

Measurement
1• Turn the meter on by pressing ON/OFF.
2
2• When the beeper sounds briefly and the
LCD displays dashes, the meter is ready.
The blinking "ZERO" indicates that the
instrument needs to be zeroed first.
Note: Temperature is a very important parameter
3 for this test method. For best results the
sample should have a temperature not
4 exceeding 20 °C.
3• Fill a cuvette up to the 10 mL mark with
unreacted sample and replace the cap.
4• Place the cuvette into the cuvette holder
and ensure that the notch on the cap is
5
positioned securely into the groove.
6
5• Press ZERO/CFM and the lamp, cuvette
and detector icons will appear on the display,
depending on the measurement phase.
6• After a few seconds the display will show
"-0.0-". The meter is now zeroed and
7
ready for measurement. Remove the cuvette.
7• Add 1 level spoon of HI 93714A Cyanide
Reagent. Remember to close the reagent
bottle immediately after use.
Note: Pay attention to the way the spoon is
8
filled: - do not overfill it;
- do not press the powder.

8• Replace the cap immediately to prevent
the escape of chlorine gas which is developed
during the reaction, and shake gently for
30 seconds.
9• Wait for 30 seconds and add the content
of one packet of HI 93714B-0 reagent.
10
Replace the cap and shake gently for 10
seconds.
10•Immediately add the content of one packet
of HI 93714C-0 reagent, replace the cap
and shake vigorously for 20 seconds.
11•Replace the cuvette into the holder and
11
ensure that the notch on the cap is
positioned securely into the groove.
