Percent Mode (%)
The percent mode displays the weight value in percentage compared to a 100% reference
mass and is used for target weighing or checking the sample variance.
Selecting the percent mode
1 Press the MODE key to select the unit % (Percent mode).
If the percent mode can not be selected, refer to "5. Weighing
Units".
Storing the 100% reference mass
2 Press the RANGE key to enter the 100% reference mass
storing mode.
Even in the storing mode, pressing the MODE key will
switch to the next mode.
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 % .
4 Place the sample to be set as the 100% reference mass on
the pan or in the container.
5 Press the
PRINT key to store the reference mass. The
balance displays 100.00 % . (The decimal point position
depends on the reference value. The reference mass is
stored in non-volatile memory, and is maintained even if the
AC adapter is removed.)
Note
The decimal point position depends on the 100% reference mass.
100% mass Minimum display
0.0100g to 0.0999g 1%
0.1000g to 0.9999g 0.1%
1.0000g to weighing capacity 0.01%
If the balance judges that the mass of the sample is too light
(under 0.01g) to be used as a reference, it displays lo .
A 100% reference mass can be stored in the non-volatile
memory and is maintained even if the AC adapter is
removed.
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.
