Measuring the density of a liquid
Density display is four decimal places. Minimum display can not change
with the SAMPLE key.
Denisty is displayed after "Mass measurement in air" and "Mass
measurement in liquid"
The procedure of each measurements is as follows:
Measuring procedure
1. Enter the density mode that "g (gram)" is displayed
and the processing indicator (
nothing on both pan and press the
RE-ZERO key to display zero.
2.
Place the sample on the pan in air.
If the weight value is stored or 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.（g lights、
Note
□ If negative value or E (out of range) is displayed, the SAMPLE
key is inactive.
Place the liquid to measure the density of in the beaker and sink
the float.
At this time, adjust so that the float is about 10 mm
below the liquid level.
3. Move the sample to the pan in liquid.
If the weight value is stored or 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.
（g turned off,
Note
□ If E (out of range) is displayed, the SAMPLE key is
inactive.
4. Enter the volume of the float.
Refer to "(5) Entering the volume of the float" and
enter.
Then press the PRINT key to return to the density mode.
5. If the density value is stored or output, press the
PRINT key to store it. If the other sample is
measured, press the SAMPLE key , and start from
measurement of weighing mode in the air. The
density unit is "
6. Press the MODE key to proceed to other modes.
