RL-TA Series Operation Manual 27
11 Gravimeter
A sample’s specific gravity can be measured by using the balance as a gravimeter. Hang the sample from the
balance using an optional hooking device. You may need to use a net, cage, string, or container to hang the
sample from the balance.
This manual describes the procedures for measuring the specific gravity of a solid by hanging it
from the balance. If you are using the optional specific gravity kit or are measuring the
specific gravity of a liquid, refer to the operation manual that comes with the optional specific
gravity measurement kit.
11.1 Measurement procedures for specific gravity
1. Preparation for specific gravity measurements.
Put the balance on a pedestal and attach the hanging hook.
Hang a cage or the like that is used for holding the sample.
As the sample weight is also measured in water, prepare a
container with water whose size is enough to put the entire
cage into the water.
In gravimeter mode, [] is displayed.
2. Measure the water temperature in the container and enter
the value into the balance.
Press and hold the Zero/Tare key to enter the temperature
setting mode and then enter the water temperature (for any
media other than water, enter the specific gravity value of
the media). (Refer to the descriptions on page 31 for the
procedures to enter the value.)
The value entered is held even after the power is turned off.
3. Reset the display to “0”.
Press the Zero/Tare key with only the cage hung to reset the
display to “0”.
