13. PERCENT MODE (Pct)
This is the mode to display the weight value in percentage compared to a 100% reference mass and
is used for target weighing or checking the sample variable.
Selecting the percent mode
1 Set
“

(
Unit

” parameter of the function table to
pct
(percent mode). For
details, refer to “5-2 Changing the Unit”.
Storing the 100% reference mass
2 Press the SAMPLE key to enter the 100% reference mass storing mode.
To return to the percent mode without storing the 100% reference
mass, press the CAL key.
3 Place a container on the weighing pan, if necessary. Press the
RE-ZERO key to cancel the weight (tare). The balance displays
100 0 pct .
4 Place the sample to be set as the 100% reference mass on the
pan or in the container.
5 Wait for the stabilization indicator to be displayed. Press the
PRINT key to store the reference mass. The balance displays
100.00 pct
. (The reference mass stored, even if the AC adapter is
removed, is maintained in non-volatile memory.)
Notes
If the balance judges that the mass of the sample is too light to be
used as a reference, it displays
lo
. Do not use the sample.
The decimal point position depends on the 100% reference mass.
（ For details, refer to the table below*. ）
6 Remove the sample.
Reading the percentage
7 Place a sample to be compared to the reference mass on the pan.
The displayed percentage is based on the 100% reference mass.
While the stabilization indicator is on, pressing the PRINT key will
output the weight value, using the RS-232C serial interface.
Note
Peripheral equipment, that is sold separately, such as a printer or a personal computer is required.
