Introduction
Thismanualexplains the operationofthe PC-820partscounting scale. The
PC-820is acomputer-based countingscale whichcanbeconfiguredand
programmedformany applicationsand toyourspecific needs.
Due to the unlimited variety of applications available for the PC-820, it is not
practical to describe in this manual all the possible specialized operations.
This manual explains only the basic application which ships from the factory
and also assumes all the functions of the scale are enabled. Your scale,
whichhasbeenconfiguredfor yourparticularapplication,maynot havethe
samedisplaysor enabledfunctions.
Major sections of this manual are headed by titles in a black bar like
Intro-
duction above.Subheadingsappear inthe leftcolumn.Instructions andtext
appear on the right side of the page. Notes, tips, warnings and special
instructions appear in the left column.
This manual is divided into the following main sections:
•UnpackingandPreparingthePC-820
•PC-820Description
•WeighingOperations
•CountingOperations
•PC-820Menus

knobs above each foot against the scale base.
Plug the unit into the appropriate power source. Keep in mind that the power
receptacle must be earth grounded and easily accessible to the user.
Press any key to activate the scale.
Upon power up the unit will briefly display an opening screen, then show the
default display mode. The scale is now ready for use. After several minutes of
inactivity the scale will go into a sleep mode. Press any key to reactivate the
scale.
Unpacking and Preparing the PC-820
The unit must be plugged into
an easily accessible outlet that
is earth grounded and of the
appropriatevoltage.

Front Panel Keys
Hard Keys
The PC-820 is a 12”x 14”scale with an attached 5”x 12”display housing.
See Figure 1. The scale base is cast aluminum enclosing a QDT®(Quartzell®
DigitalTechnology) weightsensor andelectronics package.Thescaleplatter
is stainless steel.
Figure 1
PC-820 front panel
The display is a 64 x 240 dot matrix which allows several lines of text and the
ability to display graphics. See Appendix A: Available PC-820 Displays .
There are five softkeys located directly below the display, a numeric keypad
to the right and six other labeled keys. The keys will be described in the next
section.
BuiltintothePC-820 are two RS-232serialports (Com1 and Com2).Com1
can also be used as an RS-485 port. See the PC-820 Service Manual for
information on setting up Port 1 as RS-485. Com2 can be a bidirectional RS-
232portor aprinter,keyboard and scannerport.
This scale has an internal database and an option card to support a remote
Quartzell®oranalog base.
The keys on the front panel of the PC-820 are of two types; hard keys and
softkeys. Hard keys are labeled directly and softkey labels appear on the
display.Softkeysfunction differently atdifferent times andtheirlabels change
asneeded.
Belowarebriefdescriptions for each ofthehard key functions:
ESCAPE Press the ESCAPE key to back out of menus or cancel a
numericentry withoutaccepting thevalue.
ZERO Press the ZERO key to establish a zero reference. When the
scale is at zero, ±¼division, the center-of-zero icon will be
displayed. When the scale is in motion the stable scale icon
will disappear. See note at left.
TARE With an empty container on the scale, press the TARE key
to enter an active tare weight. The display shows net weight.
ENTER Press the ENTER key to accept displayed information,
whether it is numeric characters you have keyed in or if it is
a choice displayed while in the menus.

Counting Operations
Toperforma countingoperation thefirststep isto obtaintheaverage weight
of each piece or the piece weight, abbreviated as pcwt. You can key in a
known piece weight or you obtain a piece weight by sampling.
Sampling consists of placing a known number of pieces on the scale and
letting the scale determine the individual piece weight. The scale uses this to
determine the count of pieces placed on the scale. The piece weight is kept
in memory until a new sample is taken.
Pieceweightsandother information can bestoredin an internal database.
Informationis storedunderpartnumbers.When yourecall apart numberfrom
the database, the piece weight, tare weights, etc. become active. This means
you do not have to resample parts each time you want to count them.
You can sample parts using the bulk or dribble modes. In bulk mode you are
prompted to place a specific number of parts on the scale all at one time.
After motion ceases the scale automatically calculates the piece weight and
goes into the count mode. This means you must have the counted parts or
sample ready to place on the scale all at once.
In dribble mode the scale prompts you to place the sample of parts on the
platform and when you are done, press the ENTER key. The scale calculates
the piece weight and puts the display into the count mode. This allows you to
count out your sample parts onto the platform.
When you press the SAMPLE softkey you are given two new softkey
choices. One is sMode. This stands for sample mode. Press this and you
canchoosebetween Bulk orDribblesampling modes. Theothersoftkey
offered is sWeight. This stands for sample weight and lets you choose from
four minimum samples weights based on the shown percent of full scale
capacity.
Follow these steps to perform a counting operation using the bulk mode:
1. Press the SAMPLE softkey. . . The scale zeroes itself and the
display prompts you to:
Load all
samples or key in sample size.
Sample Size = 5 . Five is the default
sample size.
2. You can place all the items or
parts on the scale
or
key in a new sample size, X,
press the ENTER key, then
place all X samples on the
scale. . . The display shows Standby. . .
computing piece weight , then the
display shows the weight and count.
3. Place the items to be counted on
the scale. . . Countandweightaredisplayed.
4. Repeat step three until you are
done with all identical items.

To perform a count while using a container, place the container on the scale
and press the SAMPLE key. The scale automatically zeroes and the scale is
ready for bulk or dribble sampling as described in the previous sections.
When you key in a number on the numeric key pad the display shows new
softkey choices. The choices are P/N, PCWT, TARE, DESC, NAME, ID, and
LOC/LOT, SET A, SET B. Press one of these softkeys to assign the keyed-
invalueto that function.Thedisplay returns tonormaloperating modewith

The database can hold up to 1000 records. A record can consist of the
following:
•PartNumber(P/N)
•TareWeight
•Piece Weight
•PieceCount
