9 Percentage Weighing
The weight of a reference sample is saved as 100%. When a sample is placed on the balance, the balance
indicates the percentage of that sample with respect to the reference sample weight.
A reference sample weight can be set by weighing an actual sample or entering a value.
* Select [
1. Set. 3] (Percentage Weighing) in Function 1.
9.1 Set a reference weight by weighing an actual sample
You can make the display indicate the weight percentage (%) of a sample with respect to a reference
sample weight.
1. Start sampling.
Make sure that the [%] sign is displayed and press and hold the
Function key for a few seconds.
(This operation may be performed with a container placed on
the balance.)
The display then blinks [
P. SEt].
The previously-saved reference sample weight blinks.
2. Put a sample on the balance.
Put the reference sample on the balance.
3. Save the reference weight.
Press the Function key.
4. Put a sample to weigh on the balance.
The display indicates the percentage of the sample weight with
respect to the saved reference sample weight.
The minimum unit is automatically selected, depending on the saved reference weight.
Min. Indication Range of Reference Weight
L -- Err
Reference weight < Lower weight limit
1% Lower weight limit
≤ Reference weight < Lower weight limit × 10
0.1% Lower weight limit
× 10 ≤ Reference weight < Lower weight limit × 100
0.01% Lower weight limit
× 100 ≤ Reference weight
You cannot set a value below the lower weight limit as a reference weight.
* The lower weight limit depends on the model. For more information, refer to Section 23: Specifications
on page 83.
