(B) Entering the weight of a sample in liquid
1 Confirm that nothing is placed on the lower pan (in liquid).
Press the
RE-ZERO
key to set the display to zero.
2 Place a sample on the lower pan (in liquid). When the
value displayed on the balance becomes stable, press
the
PRINT
key. The sample weight in liquid is confirmed
and the balance will return to the density mode (Go to
"Step 2 Selecting a parameter to set").
3 Remove the sample from the lower pan.
Note
If an unstable value, a negative value or
e
(
error
)
is displayed, the
PRINT
key is disabled.
The
SAMPLE
key can not be used to change the
minimum weighing value.
(C) Entering the density of a liquid
Two ways to set the density of a liquid are available in the function table, "Liquid
density input (
ldin
): by entering the water temperature or by entering the density
directly.
Entering the water temperature
(
ldin 0
)
The water temperature currently set (unit:°C, factory setting :
25°C) is displayed.
Use the following keys to change the value.
RE-ZERO
key...To increase the temperature by one degree. (0°C is displayed after 99°C)
MODE
key .......To decrease the temperature by one degree. (99°C is displayed after 0°C)
PRINT
key........To store the change, display
end
and return to the density mode.
(Go to "Step 2 Selecting a parameter to set")
CAL
key...........To cancel the change and return to the density mode.
(Go to "Step 2 Selecting a parameter to set")
The relation between the water temperature and density is shown below.
