Measuring the density of a liquid
(
specific gravity
) ( d5 1 )
Note 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 of a float in air" and "Mass measurement
a float 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 the weighing pan and press the
RE-ZERO key to display zero.
2 Place the float on the weighing pan. (g lights.
blinks.)
If the weight value of the float 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 Pour in the liquid for the density measurement and
submerge the float in the liquid. At this time, confirm
that the float is approx. 10 mm under the liquid
surface. Wait until the display is in the stable state to
take a reading.
If the weight value is output, press the PRINT key.
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
SAMPLE key is inactive.
4 Inputting the volume of the float
Refer to “Entering the volume of a float” and Input the
volume of a float. Press the SAMPLE key to
proceed to the next step.
5 If the density value is 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 Press the MODE key to proceed to other modes.
