(PCS) FRONT PANEL PARTS COUNTING
NOTE: Access to the pieces function, via the front panel, is disallowed if a PDA is functional or 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.
1. Press the FUNCTION switch (or MODE and
RANGE switches simultaneously for dual
range models).
Display cycles repeatedly through PCS, HI-OK-LO, CAL1, CAL2, T ,
and CAL 100.
2. Press the MODE switch 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 switch.
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 switch.
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 switch.
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 switch 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 switch.
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 switch again.
You are now in the weighing mode you used just before selecting the
parts counting mode.
(HI-OK-LO) CHECKWEIGHING / PROCESS CONTROL LIMITS
1. Press the FUNCTION switch (or MODE and
RANGE switches simultaneously for dual
range models).
Display cycles repeatedly through PCS, HI-OK-LO, CAL1, CAL2, T ,
and CAL 100.
2. Press the MODE switch when HI-OK-LO
appears on the display.
HI, OK, and LO flash.
3. Press the ZERO switch. HI flashes and zeros are displayed.
4. Place weight on the pan which represents the
upper control limit of the acceptable weight
range.
HI flashes and the upper weight is displayed.
5. Press the ZERO switch. LO flashes and the upper weight is displayed.
6. Remove the upper limit weight and place
weight on the pan which represents the lower
control limit.
LO flashes and the lower weight is displayed.
7. Press the ZERO switch. HI-OK-LO briefly appears and then OK and the lower weight 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 switch. The balance then returns to normal operation.
