OPERATIONAL GUIDE
INITIAL PREPARATION
The instruments are supplied complete with batteries. For placing the
batteries inside the meter, see page 14.
To prepare the instrument for use, connect the sodium sensitive
electrode FC300B to the input socket on the top of the instrument.
Connect the temperature probe to the temperature socket too. The
temperature probe can be used independently to take temperature
measurements. If the probe is disconnected, 25.0 °C (72.0 °F) is
displayed with °C or °F symbol blinking.
Turn the instrument ON by pressing On/Off.
At start-up the display will show all
the used segments for a few seconds (or
while the button is held), followed
by the percentage indication of the
remaining battery life. The meter is
now ready to operate.
After measurement switch the instrument off, and remove the electrodes.
For a fast and accurate measurement, the electrode should be stored
in a solution with a Na/NaCl concentration similar to the sample to
be measured. Upper the rubber sleeve after use.
The auto-off feature turns the instrument off after a set period
(default 20 min) to save battery life. To set another period or to
disable this feature, see SETUP menu on page 11.
In order to take accurate measurements, make sure the instru-
ment is calibrated before use (see page 11 for HI 931101 and
page 13 for HI 931100 & HI 931102).
For greatest accuracy, calibration should be performed (or at least
verified) every day for measurements taken in the same type of
samples (e.g. cheese) or every time the sample type is changed (e.g.
cheese, meat, sea water, etc.).
The best working temperature is around 20-25°C (68-77°F). For
greater accuracy, perform the calibration of the meter with standard
solution at a temperature as close as possible to the temperature of
the sample (±1°C/±2°F).

TAKING SODIUM MEASUREMENTS
Remove the protective cap of the FC300B
sodium-sensitive electrode and, if possible,
rinse it with some of the sample you are
going to measure.
Lower the rubber sleeve to get the junction
to work properly.
Immerse the tip of the FC300B electrode
(2.5cm/1" i.e. the electrode junction must
be completely immersed) into the sample
to be tested without touching the bottom
of the beaker.
Wait for up to 10 to 15 minutes to allow
for the electrode to adjust and stabilize, i.e. until there is no drifting
for at least a couple of minutes.
During measurement, if possible, the sample should be gently stirred
(100 rpm).
pNa (for HI931101) and NaCl% (for HI931102)
measurements
Press the MODE key during mea-
surement to convert the displayed
value of HI931101 to pNa.
pNa = -log aNa
where aNa is the activity of ion
Na.

10
Press the MODE key during measure-
ment to convert the displayed value of
HI931102 to %.
Press the same key to return to g/L
measurements.
AFTER USE
Turn the meter off by pressing the ON/OFF
key again.
For a faster and accurate measure, the elec-
trode should be stored in a solution with a
Na/NaCl concentration similar to the sample
to be measured.
Upper the rubber sleeve after use.
For infrequent use (once a month or less)
store the electrode dry. Before using it again,
let it condition overnight in HI7081/HI8081
(30.0 g/L NaCl) or HI7086/HI8086 (23 g/
L Na 1M).
To avoid very long response time, do not store or rinse the
electrode with deionized water. Never rub or blot the electrode.
TEMPERATURE MEASUREMENT
The temperature can be measured inde-
pendently.
•Immerse the temperature probe at
least 1 cm (½”) in the prepared sample.
•Wait for the reading to stabilize. The
temperature of the solution will be shown
on the lower part of the display.
Notes:• If the temperature is out of
range, the last range value
will be displayed and the
“°C” (“°F”) tag will blink.
•If the temperature probe is not connected, the 25.0 °C
value will be displayed together with the blinking tags
“No Temp Probe” and “°C” (“°F”).
