Setting the density of a liquid
1. Press the UNITS key to select
SG
.
2. Press and hold the UNITS key to display liquid density input mode.
ldin = 0: Water temperature
This shows 25 °C.
ldin = 1: Liquid density
This shows ρ = 1.0000 (g/cm
3
).
3. Using the RE-ZERO (to increment the value) and SAMPLE key (to shift the
selected digit), set the value and press the PRINT key to store.
To cancel the setting procedure and return to the density measuring mode, press
the
UNITS key. The input value is not stored.
The relation between the water temperature and density is shown below.

Example of density measurement
Selecting the SG measurement mode
1. Press the UNITS key to select
SG
.
(The weight unit is “g”.)
The weighing unit is “g”.
The display shows that HI blinks and the balance
is measuring weight in air.
When the display does not show zero, press the RE-ZERO key to set the
display to zero.
