(PCS) Front Panel Parts Counting:
Note: Access to the PCS function via the front panel is disallowed if bi-directional RS-232 is enabled. RS-232 is enabled by
selecting local control (LC) oFF (see RS-232 Front Panel Configuration section for details). Local control ON means the
front panel controls the balance.
User Action Balance Response
1 Press the FUNCTION button (or MODE and
RANGE buttons simultaneously for dual
range models).
Display cycles repeatedly through PCS, HI-OK-LO, CAL1, CAL2, T , and
CAL 100.
2 Press the MODE button when PCS appears on
the display.
PCS and 0 flash. This is a prompt to zero the balance with the container that
will hold the pieces on the weighing pan.
3 Place the empty container on the pan, wait 10
seconds, and then press the ZERO button.
PCS and 10 flash. This is a prompt to place 10 pieces in the container.
4 Place 10 pieces in the container, wait 10
seconds, and then press the ZERO button.
PCS continues to flash and OK appears on the display while a stable weight is
obtained. Then 10.000, or something very near it, appears on the display. The
number of decimal places depends on the weight. PCS continues to flash. This
prompts you that you may now increase the sample size in order to obtain a
more statistical significant sample which yields a more accurate parts counting
conversion factor. The decimal places aid you in rounding the piece count
correctly as the sample size increases.
5 If you want a larger sample size to be used in
computing the parts counting conversion
factor, add pieces (the balance will count
them) until the decimal part is near 0.7 or 0.3.
Then press the ZERO button.
The balance will round to the nearest whole number but still show the decimal
places. This step may be repeated as many times as you desire.
6 When you are satisfied the sample size is large
enough, press the ZERO button once again.
The balance rounds to the nearest whole number, the decimal places disappear,
and PCS lights steadily.
7 When you wish to count something else, press
the MODE button.
You are now back at Step 2 with a flashing PCS and 0.
8 If you want to exit the counting mode, press
the MODE button again.
You are now in the weighing mode you used just before selecting the parts
counting mode.
(HI-OK-LO) Checkweighing / Process Control Limits:
User Action Balance Response
1 Press the FUNCTION button (or MODE and
RANGE buttons simultaneously for dual
range models).
Display cycles repeatedly through PCS, HI-OK-LO, CAL1, CAL2, T , and
CAL 100.
2 Press the MODE button when HI OK LO
appears on the display.
HI, OK and LOPCS and 0 flash.
3 Press the ZERO button. HI flashes and zeros are displayed.
4 Place weight on the weighing pan which
represents the upper control limit of the
acceptable weight range.
HI flashes and the upper weight limit is displayed.
5 Press the ZERO button. LO flashes and the upper weight limit is displayed.
6 Remove the upper limit weight and place
weight on the weighing pan which represents
the lower control limit of the acceptable
weight range.
LO flashes and the lower weight limit is displayed.
7 Press the ZERO button. HI OK LO briefly appears and then OK and the lower weight limit are
displayed.
8 Remove the lower limit weight. LO appears and zeros are displayed.
The balance is now ready to checkweigh samples. The balance displays OK along with the weight of the sample if the sample is within
the acceptable weight range. If the sample is too heavy, HI and the weight are displayed. If the sample is too light, LO and the weight are
displayed. The weight limits are stored until the balance is turned off.
To exit check weighing, press the MODE button. The balance then returns to normal operation.
