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. This series balance is equipped with the Automatic Counting
Accuracy Improvement (ACAI) function to improve the counting accuracy.
Note
※
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
pC5
(
pC5
= unit
)
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 5, 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.
25 0
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. When PRINT key pressed, unit mass is stored and changes the count
display. (eg: when the number is 25,
25
pC5
is displayed.
Note
※
If the balance judges that the mass of the samples is TOO light
to acquire accurate weighing, it displays an error requiring the
addition of more samples to the specified number and press the
PRINT key. When the unit mass is stored correctly, the balance
proceeds to the counting mode.
※
If the balance judges that the mass of the samples is too light and is
not adequate to be used as the unit mass, it displays
lo
.
※
Registered unit mass is remembered even when the power is turned off.
