5-2 Counting Mode (PCS)
This is the mode to determine the number of objects in a sample based on the standard sample unit
mass. Unit mass means the mass of one sample. The smaller the variables in each sample unit
mass is, the more accurate the counting will be. The GP series balance is equipped with the
Automatic Counting Accuracy Improvement (ACAI) function to improve the counting accuracy.
Note
If the sample unit mass variable, the difference from sample to sample, is too large, it may
cause a counting error.
Selecting the counting mode
1 Press the MODE key to select pcs (counting mode).
Storing a sample unit mass (Weighing input mode)
2 Press the SAMPLE key to enter the sample unit mass
storing mode.
3 To select the number of samples, press the SAMPLE key
several times. It may be set to 10, 25, 50 or 100.
Note
A greater number of samples will yield more accurate
counting result.
4 Place a container on the weighing pan, if necessary.
Press the RE-ZERO key to cancel the weight (tare). The
number specified in step 3 appears.
e.g.: 25 0
pcs
is displayed if 25 is selected in step 3.
5 Place the number of samples specified on the pan. In this
example, 25 pieces.
6 Wait for the stabilization indicator to come on. Press the
PRINT key to calculate and store the unit mass. The
balance displays 25
pcs
(counting mode) and is set to
count samples with this unit mass. (The sample unit mass
stored, even if the AC adapter is removed, is maintained
in non-volatile memory.)
To improve the accuracy of the unit mass, proceed to step 8.
Notes
If the balance judges that the mass of the samples is too
light and can not be stored as the unit mass, it displays
lo .
If the balance judges that the mass of the samples is too light to aquire accurate weighing, it
displays an error requiring the addition of more samples to the specified number. In the
example above,
1
50-
pcs appears, requiring 25 more samples. Add 25 samples and press
the PRINT key. When the unit mass is stored correctly, the balance proceeds to the counting mode.
Key entry of the unit mass value (digital input mode) is possible. For details, refer to “11-4
