Unpacking and Startup

Counting Scales:

After opening the shipping carton, remove the molded foam top from the carton. (On
2 lb. and 5 lb. capacity scales the platform is packaged on top of this foam, remove it
first and lay it aside.)

Gently lift and remove the stainless steel platform cover only.

Remove any options which may be packed with the scale.

Carefully remove scale from the packaging by grasping both sides of the base.
DO NOT LIFT SCALE BY THE TOP SPIDER OR SUB-PLATFORM ASSEMBLY.

Place the scale on a stable, level surface for operation.

Adjust the corner leveling feet until the level bubble indicates the unit is level. Firmly
tighten hex jam nuts on the leveling feet. (Any time the scale is relocated, it should be
leveled.)

Remove the protective plastic wrap from the platform and place the platform on the
spider.

To activate the scale, plug the line cord into any grounded 50/60 hertz 120 volt outlet.

Operational Features

Automatic Zero-Tracking (AZT) - Maintains the system zero and is normally set to +/-

1/4 of the display resolution.

Count/Weigh - Scale is capable of both counting and weighing functions. The count
may be turned off on the 7600 if not needed.

Four Selectable Sample Sizes - Four different sample sizes may be entered into the
scale memory during programming.

Counting Functions - A variety of different counting methods may be employed,
depending on type of counting selected during calibration.

Sample Update - Piece weight accuracy may be improved after the initial sample by
adding a quantity of parts between 10% and 100% of the original sample to the
platform. When this is done the scale will recalculate the piece weight, display the new
percent error/accuracy for 2 seconds and then return to the counting mode.

Second Base - An optional second base is available to expand the capacity of the
scale.

Peak/Hold – Captures the peak reading directly (based on filter settings) or after preset
number of “stable” readings.

Accumulation – Based on count or weight.

Counting Scale Connectors:

The following connectors may be accessed through the opening on the bottom of the
scale.

D-Subminiature Connector (9-pin) - Used with RS-232 Interface.

Remote Display Connector - Used to connect a remote display option to the scale.

REMOTE BASE CPC Style connector (8 pin) - Same as indicator wiring.

weight, if any, and puts it into the piece weight entry mode.
TARE Button - Will tare off any weight setting on the platform and enter it into the tare
memory.
KEYPAD TARE Button - Will display whatever tare is presently stored in the tare
memory and puts the scale into the keypad tare entry mode.
BASE Button - Used to switch the scale between base 1 and base 2, when the
second base option is installed.
% Button - Used to display the percent of error, or percent of accuracy. (Only if these
features have been selected during programming.)
ID Button - Will display whatever ID number is presently stored in the ID memory
and puts the scale into the ID entry mode.
CHECK Button - Pressing this button will cause the scale to initiate the diagnostic
countdown. It may also be used as a continue key if the scale should freeze on any of
the diagnostic numbers during countdown.
CLEAR Button - Used when the scale is in one of the data entry modes. Pressing this
button once will put a decimal point onto the display and pressing it a second time will
clear the display.
ENT Button - Used when the scale is in one of the data entry modes. Button is used
to enter information into the system memory.

Menu Access:

To access instrument configuration, calibration or to enable options, depress the “Zero”
key for five seconds.
The Audit Trail counters (“Pxxxx” and “Cxxxx”) are displayed first followed by access
code request (“AC?”). The initial factory setting is “0000” which is entered “AC0000” and
“Print”. If no entry is made, instrument returns to operate mode. Stepping the “Zero” key
when “AC?” is on, will display software version, display check and keypad test.

Configuration Blocks: 50, 60, 70 and 80 may be accessed form the front panel of the

scale by pressing and holding the PRINT button for 2 seconds. The scale will then
display CFG 60. At this point, you can press ENT to select this category or key in the
number of any of the other accessible categories.

Configuration/Calibration Main Blocks: 10, 20, 30, etc can be stepped to directly
by incrementing “CAL 10” to “20” and “enter” (Options are CAL 1). The sub
parameters need to step through to the next “main” before a direct change.

From any “main” point, exit by changing to “CAL 0” and “enter”. A “store” “no”
will need to be changed to “yes” to save any changes. Changing to “CAL 0” from
within “CAL 40” allows exit prior to adjusting span.

NOTE: During the setup procedure each step will be printed to any device interfaced to

the RS-232 port. If options are not present, steps will not appear.

CAL 80 Formatted print slot programing

BUILDING A FORMATTED PRINT

The user defined formatted print is the string of information sent from the RS-232 port
when the PRINT button is pressed, or the scale receives an SRP command from a
computer or terminal. The user selects the format of this string by entering two digit print
codes into the 20 available print slots, PSL 81 through PSL 101. When you are finished
entering data to construct the formatted print, "99" is entered to mark the end of print
formatting.

EXAMPLE OF BUILDING A FORMATTED PRINT
To build a simple formatted print that could be sent to a ticket printer the following print
codes could be entered:

PSL 81 - 30 (gross w/ prefix & suffix.) The result:
PSL 82 - 65 (CR/LF)

PSL 83 - 32 (net w/ prefix & suffix.)

COMMAND FORMATS

The Model 7600 can be controlled from an external device (such as a computer or
terminal) by various commands, each three letters long, which represent related English
phrases or words. For example, to tell the scale to zero, type ZRO followed by a car­riage return.
The basic command formats are:

[<add>]<cmd><cr>

<cmd> [<xx.xx>]<cr>

Where <cmd> is a three-letter command, <add> is a scale address number (0-255),
<cr> represents a carriage return, and <xx.xx> is a mixed number, the brackets [ ] are
used to indicate an optional part of the command.

Examples:

SRP<cr> Send a formatted print

ITW 13.43<cr> Instructs scale to set tare weight

to 13.43 in the current unit

5 SGW<cr> Instructs the scale with address #5 to

send the Gross weight.

25

COUNTING

An electronic counting scale counts parts by knowing the weight of a single piece,

dividing that into the total weight on the scale and displaying the result. With the 7600,

this piece weight may

be entered into the scale by one of two methods:

FIRST: Counting out a "sample" quantity of the parts and placing them onto the

scale. The scale will take the weight of the sample, divide it by the known
quantity and derive a piece weight used to count the rest (or "bulk") of the
parts.

SECOND: If the individual piece weight of the parts is already known, this weight

value may be entered into the scale via the keypad.
SAMPLE SIZE:
If the "sample" method of piece weight entry is used, the total weight of the sample must
be at least 0.04% of platform capacity or the scale will not recognize the sample. When
sampling, it is always advantageous to use the largest sample possible. Not only does
the larger quantity tend to average variations in the weight of individual pieces, but the
heavier sample weight improves the counting accuracy of the scale itself.

NORMAL COUNTING PROCEDURE

ONE SWITCH COUNTING - The 7600 is normally shipped from the factory set

up to follow this counting procedure. Unless your 7600 has been programmed for one of

the

alternate counting choices, this procedure is the only one necessary to learn.

NORMAL COUNTING - Using Sample

1. If a container will be used to hold items being counted, place it on the platform.

2. Press the SAMPLE SET button. The scale zeroes. "AddXXX" appears on the display

(where "XXX" is one of the four pre-programmed sample sizes.). Repeated pressing
of the switch successively displays the four sample sizes entered during calibration.

3. If a different sample size is required, key in the desired sample size (do not press

ENT).

4. Place the entire sample on the platform at one time. (If the scale has been

programmed to show the percent of error; this value will be displayed momentarily at
this time.) The scale will now automatically switch to the count mode, displaying the
number of parts in the sample.

5. All of the remaining parts may now be added to the scale and counted. ZERO,

TARE and KEYPAD TARE buttons may now be used without affecting the piece
weight.

6. To count a different part, return to step one.

26

NORMAL COUNTING - Keypad Piece Weight Entry
If the individual weight of the parts being counted is known in advance the piece weight
may be entered through the keypad. This eliminates the need for the sample set
operation. (If the percent of error feature has been selected in programming, the scale
will not calculate the percent of error when keypad entry of piece weight is used.)

1. Select the appropriate weighing unit (primary or secondary) for the piece weight

being entered by pressing the UNITS/4 switch.

2. Press the PIECE WEIGHT switch. The display will alternately show "PC" and any

previously stored piece weight.

3. Key in the weight of one piece and press ENT.

4. The scale will go into the count mode.

5. If a container will be used to hold the parts, place it onto the scale and use the

ZERO and/or TARE buttons to zero the scale. Add the parts to the scale at this time.
NOTE: The parts in a full container may also be counted by placing the full container
onto the scale and using KEYPAD TARE to key in the tare weight of the container.

ALTERNATE COUNTING METHODS
The 7600 may be programmed to perform a wide variety of different counting methods.
the following section describes these counting methods, refer to the "Calibration and
Programming Manual" for information on setting your scale to perform one of these.

Two Switch Counting
The 7600 can be programmed so that when the scale is in the sample set mode, the
sample will not be accepted until the ENT button is pressed. This allows parts to be
added to the platform one at a time, where as with the one switch method all of the
sample must be added at once.

Top-End Counting
The total number of items in an unsealed container can be determined without removing
the items from the container (except a sample). The container with parts is placed on
the platform and the piece weight is calculated when a sample quantity is either added
to (one switch) or removed from (two-switch operation) the container. Based on the
piece weight, the total number of items in the container is displayed.

Automatic Sample-to-Bulk Counting
This method requires that the scale be configured with two bases, a "sample" and a
"bulk" base. The lighter capacity "sample" base is used to calculate the piece weight,
and the parts are counted on a heavier capacity "bulk" base. In most cases, higher
counting accuracy is achieved with this method because the calculated piece is more
precise when the sample is weighed on the light-capacity sample base. In normal
operation, when the sample is placed on the sample base, the scale automatically
switches to the bulk base and items to be counted are placed on the bulk base.

27

Counting by First Determining Error of Count (One-Switch Method using
Automatic Sample Update)

The percent error/accuracy of count can be updated by adding more items to the
sample after the initial sample size is placed on the platform and the percent
error/accuracy has been displayed. In normal operation , the sample is placed on the
platform and a percent error/accuracy is momentarily displayed, followed by the count.
More pieces are then placed on the platform in the range of 10% to 100% of the original
sample. A new piece weight is calculated based on the larger sample size, and the new
percent of error/accuracy will be momentarily displayed. This may continue until a
satisfactory percent of error/accuracy is achieved.

Counting by First Determining Error of Count (Two-Switch Method)
The percent error of count can be determined before the piece weight is established.
Sample pieces are added to the platform until the percent of error/accuracy is
acceptable. The sample size (number of pieces) is then keyed-in and entered, and the
scale is ready to be used for counting.

Piece Weight Displayed as Weight Per 1000 Pieces
If selected in calibration, the piece weight can be displayed as weight per 1000 pieces.
This option is useful when the items being counted are very light and the piece weight
for one item would be an extremely small number. When entering the piece weight
through the keypad (for normal counting), enter the weight for 1000 items if the piece
weight is to be displayed as weight per 1000 pieces.

Negative Counting
This method is used to count the number of items removed from a container without first
knowing the piece weight. The number of items removed from the container is shown on
the display as a negative number.

Normal Operation with Two Switch Counting

1. If a container will be used to hold items being counted, place it on the platform.

2. Press the SAMPLE SET button. The scale zeroes. "AddXXX" appears on the display

(Where "XXX" is one of the four pre-programmed sample sizes.). Repeated pressing
of the switch successively displays the four sample sizes entered during calibration.

3. If desired, a different sample size may be keyed into the scale. As this number is

entered, the word "Add" will disappear and only the count indicator will be lit to
indicate that the scale is in the sample entry mode.

4. The sample may now be placed onto the scale, all at once or one at a time. (If the

percent of error feature has been selected in programming, the percent of error will
be displayed as the parts are placed onto the platform. The more parts that are
added, the lower the percent of error will be.)

5. Press the ENT button. The scale will switch to the count mode and display the

sample count.

6. The remaining parts to be counted may now be placed onto the scale.

28

Normal Operation with Automatic Sample to Bulk Feature
The second base option needs to be installed and calibrated for automatic
sample to bulk to operate. Base one is always the sample base and base two is
always the bulk base.

1. Press the BASE/1 switch to select the bulk base. (Base two indicator should
be lit)

2. Press the ZERO switch to zero the bulk base.

3. If an empty container will be used to hold items on the bulk base place it on
the platform and press either the ZERO or TARE switch.

4. If a full container will be counted on the bulk base. Place the container on the
platform, press the KEYPAD TARE switch and key in the weight of the
container, press ENT.

5. If a container will be used to hold the sample on base 1, place the container
on the scale at this time.

6. Press the SAMPLE SET button. The scale will switch to the sample base
(base 1). "AddXXX" will appear on the display (where "XXX" is one of the four
pre-programmed sample sizes). Select the desired sample size by repeatedly
pressing the SAMPLE SET switch, or key in an alternative sample size.

7. If the scale is programmed for a one-switch operation place the entire sample
on the sample base all at one time. The scale will momentarily display the
percent error/accuracy (If selected in calibration.), switch to the bulk base and
enter the counting mode. The bulk base is now ready to count the parts.

8. If the scale is programmed for a two switch operation, place the sample parts
onto the platform all at once or one at a time. The display will show the
percent of error/accuracy (If selected in calibration.). When all of the sample
parts are on the scale press ENT. The scale will switch to the bulk base and
enter the count mode. The bulk base is now ready to count the parts.

9. At this point ZERO and TARE switches may be used without affecting the
piece weight.

Top-End Counting (One-Switch Method; Sample Added)

1. Press ZERO to zero the scale.

2. Place container with parts on the platform.

3. Press KEYPAD TARE, key in the tare weight of the container, then press
ENT.

4. Remove the sample from the container.

5. Press the SAMPLE SET switch. "AddXXX" will appear on the display (where
"XXX" is one of the four pre-programmed sample sizes). Select the desired
sample size by repeatedly pressing the SAMPLE SET switch, or key in an
alternative sample size. IMPORTANT:The displayed sample size must
equal the number of sample items removed.

6. Place the sample pieces that were removed back into the container. The
scale will momentarily display the percent error/accuracy (If selected in
calibration.) and enter the count mode.

7. The display will show the total count for the items in the container.

29

Top-End Counting (Two-Switch method; Sample Removed)

1. Press ZERO to zero the scale.

2. Press KEYPAD TARE, key in the tare weight of the container, then press

ENT.

3. Place the container with contents on the platform and press the SAMPLE
SET switch. "AddXXX" will appear on the display (where "XXX" is one of the
four pre-programmed sample sizes). Select the desired sample size by
repeatedly pressing the SAMPLE SET switch, or key in an alternative sample
size.

4. Remove the displayed sample quantity from the container. The display will show the
percent error/accuracy (If selected in calibration.). Press ENT.

5. The scale will enter the count mode and display the number of parts in the container.

6. Return the sample pieces to the container.

Counting by First Determining Error of Count using Automatic Sample
Update (Normal Operation; One-Switch Method)

1. If a container will be used to hold items being counted, place it on the

platform.

2. Press the SAMPLE SET switch. "AddXXX" appears on the display (where
"XXX" is one of the pre-programmed sample sizes). Select the desired
sample size by repeatedly pressing the SAMPLE SET switch, or key in an
alternative sample size.

3. Place the sample pieces on the platform simultaneously. The Percent
error/accuracy will be momentarily displayed and the scale will enter the
counting mode.

4. To either decrease the percent of error or increase the percent of accuracy,
place more items on the platform in the range of 10% to 100% of the original
sample quantity. A new piece weight is calculated based on the larger sample
size, the new percent of error/accuracy is momentarily displayed and the
scale returns to the count mode. This may continue until the desire percent
error/accuracy is achieved.

5. Removing the original sample or adding a quantity of parts greater than the
original sample will disable the automatic update feature.

30

Counting by First Determining Error of Count (Two-Switch Method)

1. If a container will be used to hold the items being counted, place it on the
platform.

2. Press the SAMPLE SET switch for two seconds. "AddXXX" will appear on the
display (where "XXX" is one of the pre-programmed sample sizes). Select the
desired sample size by repeatedly pressing the SAMPLE SET button or key
in a new sample size.

3. Place the sample onto the platform all at one time (this should be done if the
parts are extremely small) or count them onto the platform one at a time.

4. The display will show the percent error/accuracy. Continue to count parts onto
the platform, as the sample increases the percent error will decrease and
accuracy will increase. When the percent error/accuracy is acceptable key in
the quantity of parts on the platform and press ENT.

Counting by First Determining Error of Count with Automatic Sample-To­Bulk Feature (Two-Switch-Method)

1. Press the BASE/1 switch to select the bulk base. (BASE 2 light should be lit)

2. Press the ZERO to zero the bulk base.

3. If a container will be used to hold items on the bulk base, place the container
on the platform and press ZERO or TARE.

4. If a container will be used to hold the sample parts, place it onto the sample
base at this time.

5. Press the SAMPLE SET switch for two seconds. "AddXXX" will appear on the
display (where "XXX" is one of the pre-programmed sample sizes). Select the
desired sample size by repeatedly pressing the SAMPLE SET switch or key
in a new sample size.

6. Place the sample onto the platform all at once (this should be done if the
parts are extremely small) or count them onto the platform one at a time.

7. The display will show the percent error/accuracy. If the percent error/accuracy
is not acceptable, continue to count parts onto the platform, as the sample
increases the percent error will decrease and the percent accuracy will
increase. When the percent error/accuracy is acceptable, key in the quantity
of parts on the platform and press ENT.

8. The scale will switch to the bulk base. Items may now be counted on the bulk
base.

Negative Counting, Sample Removed (Two Switch Method)

1. With nothing on the scale platform, press the TARE to set tare to zero.

2. Place the container with contents on the platform.

3. Press the SAMPLE SET switch. “AddXXX” will appear on the display (where
“XXX” is one of the four pre-programmed sample sizes). Select the desired
sample size by repeatedly pressing the SAMPLE SET switch, or key in an
alternative sample size.

4. Remove the displayed sample quantity from the container. The display will
show the percent error/accuracy (If selected in calibration). Press ENT.

5. The scale will enter the count mode and display the number of parts removed
from the container as a negative number. Removing pieces increases the
negative count.
