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. - Page 9 TAKING SODIUM MEASUREMENTS Remove the protective cap of the FC 300B 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 (2.5 cm/1"...
- Page 10 Press the MODE key during measure- ment to convert the displayed value of HI 931102 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.

Page 11: Calibration
CALIBRATION In order to obtain accurate measurements, frequent calibration is recommended. For better results, calibrate at a temperature close to that of the solution to be tested (no more than ±3°C apart). The instrument can be calibrated in 1 or 2 points. Two-point calibration is always recommended for better accuracy. - Page 12 • Remove the protective cap of the electrode and rinse it with some of the buffer calibration solution you are going to use first. • Lower the rubber sleeve to get the junction to work properly.

Note: ACCU criteria is recommended. SPECIAL APPLICATIONS & ADDITIONAL INFORMATION HOW TO MEASURE SODIUM CHLORIDE IN CHEESE AND MEAT (HI 931100 & HI 931102) 1. Take a sample of cheese or meat to be analyzed. 2. Grind the sample. 3. Pour a quantity of X g in a glass beaker. - Page 17 4. Cover the beaker to prevent any spilling during stirring, place the beaker on the top of a hot plate stirrer and agitate the sample at 40-50°C (104-122°F) for 15-20 minutes. 5. Let the sample cool to the ambient temperature, then filter it. 6.

Page 21: Lcd Message Guide
The instrument is provided with the BEPS (Battery Error Prevention System) feature, which automatically turns the instrument off when the batteries level is too low to ensure reliable readings. At start up the display will show “0 bAtt” message for a few seconds, then the instrument automatically turns off. -
Page 22: Fc300B Conditioning & Maintenance
If the bulb and/or junction are dry, soak the electrode overnight in HI 7081 NaCl 30.0 g/L solution before using with the HI 931100 or HI 931102 sodium meter. Soak it overnight in HI 7086 or HI 8086 Na 23 g/L solution before using with the HI 931101 sodium meter. - Page 23 For frequent use in different samples (1 or 2 times per week), store the electrode in HI 7081 or HI 8081 (30.0 g/L NaCl) if used for NaCl measurements (in conjunction with HI 931100 or HI 931102). Store the electrode in HI 7080 or HI 8080 (2.3 g/L Na) if used for Na measurements (in conjunction with HI 931101).
