Procedure for Use
2.1 Measuring solid density
1
Set-up Function 1. (See operation manual of the balance「4
Function 1」)
・Set the system in the solid density measurement mode [ ].
・Select the media to be used. If water is to be used, set [] to [].
If any other medium to be used, set to [].
・For enabling data output, set Output Data [] and Automatic Output
[].
2
Put water or other medium into the accessory tank as appropriate.
3
If water is used, measure the water temperature using accessory thermometer.
4
Set applicable coefficients ( See ”5 Coefficient Setting” ).
If the water is used
5 Set the density measurement kit and the water tank in the place. Turn off the balance
power and then turn it on again.
6
Measure the density of a solid object according to ”3
Solid Density measurement
mode”.
2.2 Precautions relating to Use
1
If water is used as medium, check the water temperature as frequently as appropriate.
2
Be careful not to spill water or other liquid on the balance. If liquids is
spilled on the balance, wipe off immediately with soft cloth.
3
If water in used as medium, add one or two drops of surface-active agent (liquid
detergent for kitchen use). It will effectively prevent air bubbles from adhering
to any measurement object.
œ Hints œ
Measurements with smaller size samples may result in some variations in the measured
specific gravity values. In particular, any sample whose specific gravity is larger tends to
show more variation.
Use as large a sample as possible for obtaining more stable measurements.

Function 1
The following paragraphs describe Function 1 items to be set for the density measurement mode.
Also refer to “Section 6.6”of the operation manual of the balance.
4.1 Item details
Media
The medium to be used in sold density measurements is set for this item.
If it is specified to use water, it is necessary to set the water
temperature upon the measurement. Otherwise, it is necessary to set
the density of the alternative medium. Refer to “5.2 Coefficient Setting”.
Output data
Output items of measurement results are to be set. This item is
functional only for solid density measurement mode. When it is set to ,
only the display value of the sample is output. When set to ,
mass of the sample, water temperature (or the density of the medium if
any other medium is used) are printed in addition to the density value.
Refer to “7
Auto output
Print Details” for details of output data.
The timing to output measurement result is set. When “Auto Output”
is disabled, pressing the Print key upon weight display (after density
measurement is done) will print the results. The most recent measurement
before the output timing will be printed. Don’t press the Print key
after power on and before any density measurement is made. You cannot
expect normal values to be printed if no measurement has been made.
When “Auto Output” is enabled, the results will be printed upon returning
to the weight display after finishing the density measurement.
Regardless of the Auto Output setting, the items set in the above
“Output Data” setting will be printed.

5 Coefficient Setting
5.1
Coefficient setting items
The following coefficients must be set before density measurement. The setting values are
different depending on the mode and medium selected. Note that the values once set are held
in the balance even after power is turned off.
Water as media
Media other than Water

Gravimeter measurement data output
(1) Output before gravimeter measurement
With the gravimeter function, the operation is with the [  ] (output once when Print
key is pressed after it is stabilized) mode, regardless of the setting by [].
(2) Output while specific gravity is displayed
[ ] is used for selecting the output contents.
The output method can also be selected by [ ].
(3) Output (print) format
When "specific gravity, weight, and actual water temperature or density of media" are all selected
in [ ], …. If "specific gravity only" is selected, only the second line value will be output.
In addition, if any statistical calculation is made for the printer, the values in the second line will
be printed being prefixed by a serial number.
Language selection between English and Japanese for printing is made by the GLP function
[ ] of Function 1.
