6-2 Counting Mode (PC)
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 GX series balance is equipped with the
Automatic Counting Accuracy Improvement (ACAI) function to improve the counting accuracy.
Notes
For counting, use samples that have a unit mass at least ten times greater than that of the
minimum display in grams.
If the sample unit mass variable is too large, it may cause a counting error.
To improve the counting performance, use the ACAI function frequently or divide the samples
into several groups and count each group.
Selecting the counting mode
1 Press the MODE key to select
pC
(counting mode).
Storing a sample unit mass
2 Press the SAMPLE key to enter the sample unit mass
storing mode.
Even in the storing mode, pressing the MODE key will
switch to the next 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
pC
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 be displayed.
Press the PRINT key to calculate and store the unit mass.
The balance displays
25
pC
(counting mode) and is
set to count samples with this unit mass. (The sample unit
mass is stored in non-volatile memory, and is maintained
even if the AC adapter is removed.)
To improve the accuracy of the unit mass, proceed to
step 8.
