Measuring the density of a solid
(
specific gravity
) ( d5 0 )
Note If the liquid temperature or the type of liquid is changed during measurement, again
input the value of the liquid density as necessary. The density display is four decimal
places. The minimum display can not be changed with the SAMPLE key.
The density (or specific gravity) is displayed after "Mass
measurement in air" and "Mass measurement in liquid".
The procedure of each measurements is as follows:
g : gram.
: the processing indicator.
1 Enter the density mode. (g lights. blinks.)
Place nothing on both pan and press the RE-ZERO key
to display zero.
2 Place the sample on the pan in air. (g lights.
blinks.)
If the weight value is output, press the PRINT key to
store it after a stable weight value is displayed.
Press the SAMPLE key to decide the weight value
in air and proceed to next step.
Note If negative value or e (out of range) is displayed,
the SAMPLE key is inactive.
3 Move the sample to the pan in liquid. (g lights.
lights.)
If the weight value is output, press the PRINT key to
store it after a stable weight value is displayed.
Press the SAMPLE key to decide the weight value in
liquid and proceed to next step.
Note If
e
(out of range) is displayed, the RANGE key
is inactive.

Inputting the density of the liquid
Refer to “Entering the density of a liquid” and set the
density of the liquid. Press the SAMPLE key to
proceed to the next step.
5 If the density value is stored or output, press the PRINT
key to store it. (Unit : . g turns off. lights.)
Press the SAMPLE key to measure another sample
and proceed to step 2.
6 If the liquid temperature or the type of liquid is changed
during measurement, input again the value of the liquid
density as necessary.
7 Press the MODE key to proceed to other modes.
