3-3 Measuring Percentage

The weight of a sample is shown as a percentage of the reference sample weight.
A reference sample weight can be set by weighing an actual sample (setting a reference
weight by weighing an actual sample) or entering a value (setting a reference weight by
entering a value).

3-3-1

Setting a reference weight by weighing an actual sample

1

Go to the function setting mode.

(Refer to Section 2-6 “Basics of Function
Settings.”)

Press and hold the [Function] key until “Func” is

displayed.

2

Select percentage weighing mode.

Press the [Zero/Tare] key several times to select

“1. SEt 3.”

3

Save the mode.

Press the [Set] key.

The percentage weighing mode is set and “%” is
displayed.

4

Start measuring the reference sample weight.

<Press and hold>

Press and hold the [Function] key. After “P. SEt” is

displayed, release the key.

The previously saved reference sample weight
blinks.

5

Save the reference sample weight.

Put the reference sample on the balance and then press

the [Function] key.

The reference weight is saved.

6

Weigh a sample.

The display indicates the percentage of the sample to the

reference sample weight.

Pressing the [Function] key toggles the display
between percentage weight and total weight.
