Sodium tartrate dihydrate is used to check the accuracy of measurement for the
analyzer.
As an ideal substance on theory, sodium tartrate dihydrate includes moisture
content of 15.66% in the molecule. But the moisture content may change due to
conditions of storage.
The moisture content of 15.0 to 16.0% is obtained by the method below.
(Unit % is based on wet sample)
Sodium tartrate is contained in food (example : wine). If it may irritate the eyes and
nose, wash with water.
The test sample can not be used repeatedly. Dispose of it as flammable matter.
In case of MS-70 MX-50 and MF-50, test sample is included in these packing list.
In case of ML-50, purchase the test sample of accessory.
Caution A hot sample pan may cause an er ror. Allow the p an t o coo l bef ore t he ne xt t est.
Measurement

Measurement
1. Enter the following parameters.
Analysis mode ......................................Standard mode (Symbol: 5td )
Drying program Heating pattern ........... Sta ndard d rying ( )
Drying temperature..... 160°C
ACCURACY.......................................... MID.
Sample quantity.................................... Approximately 5 g is selected by
ACCURACY automatically.
Measurement unit ...................................... M oisture cont ent
2. Pre-heating process.
Put a sample pan, instead of a sample, on the pan.
Press the START key to heat it. The analyzer
temperature becomes equilibrium.
3. Press the RESET key to make zero display.
Spread the sample as evenly as possible.
4. Press the START key to start the measurement.
The result is displayed after 8 minutes normally.
If the results is between 15.0 to 16.0%, the analyzer
works properly.
5. Press the following key to complete the measurement.
ENTER key ..... Outputs (Prints) the results.
SELECT key ... Returns to the weighing mode.
RESET key ..... Returns to the weighing mode and
displays zero.
