Measuring the density
(
specific gravity
)
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
RANGE
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 stored or output, press the
key to store it after a stable weight value is displayed.
Press the
RANGE
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
RANGE
key is inactive.
3 Move the sample to the pan in liquid. (g lights. lights.)
If the weight value is stored or output, press the
key to store it after a stable weight value is displayed.
Press the
RANGE
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.
4 If the density value is stored or output, press the
key to store it. (Unit : .
g turns off. lights.)
Press the
RANGE
key to measure another sample
and proceed to step 2.
5 If the liquid temperature or the type of liquid is changed
during measurement, input again the value of the liquid
density as necessary.
6 Press
the
MODE
key to proceed to other modes.
