Model 3275 Checkweigher User’s Manual
The Model 3275 Checkweigher is a reliable, easy to operate, high speed
weighing scale, designed to allow entry of a target weight, along with se-
lected over and under weight limits for the rapid processing of items that
must be checked for conformity to a precise weight range. It may be used in
stand-alone or interfaced applications. The Model 3275 incorporates ad-
vanced electronic design, including a graphic over/under display, optional
handheld remote keypad and serial multi-scale communications. The scale
is housed in a watertight enclosure to permit use in wet environments and
can be washed down as necessary to meet sanitary requirements.
This scale has been calibrated and inspected for mechanical and electronic
integrity prior to shipment. It should be free of defects and in perfect operat-
ing condition upon receipt. To confirm this, the scale should be inspected
immediately for any physical damage incurred in transit. If the scale is
damaged, contact your local Weigh-Tronix supplier.
Place the scale on a stable, non-vibrating, level surface. Adjust the platform
feet so that the platform is level and all four feet are in equal contact with the
surface, then tighten the lock nut on each of the feet. Use the leveling
bubble to make the proper adjustment.
The scale requires a 117 VAC, 50/60 Hz power source, isolated from
electrical noise inducing equipment such as motor starters, fluorescent
lighting, etc. The scale is supplied with a UL standard 3-prong plug for AC
operation and must be connected to an outlet which provides a third wire
earth ground to insure proper operation and safety. The ground wire must
be connected to the building safety (earth) ground and neutral bus at the
main fuse box.
Print out of checkweighing transactions may be obtained by manual key
actuation or by automatic transmission when the scale is stable and a
positive net weight is present. Automatic transmission is selectable in the
scale configuration menu.

Requirements
Connecting the scale to an
outlet without a safety ground,
bypassing the safety ground,
or in any other way disrupting
the safety earth ground, could
make the scale an electrical
shock hazard, or could affect
its operation.

6Model 3275 Checkweigher User’s Manual
When the scale is stable and displays a positive net weight, press the PRINT
key to transmit data (weight display will flash).
The scale initiates an automatic transmission when the scale is stable, a
positive net weight is present and the scale has registered a minimum of 20
graduations of motion since the last print (weight display will flash).
The data transmitted when a print command is actuated is selected in the
scale configuration menu. The choices of data sent are:
1. Displayed weight or displayed weight with status identification (over,
accept, under)
2. Displayed weight with status identification and weight deviation from
target weight.
Up to 32 Model 3275 checkweighers can be connected through their respec-
tive RS-485 I/O ports to an IBM PC/AT®* or compatible computer which may
be used as a controller for the scale(s). The controller continuously polls the
connected scales and can handle 5 transactions per second.

The display and control keys are located in a stainless steel housing on
top of a stainless steel column. See Figure 1. The housing can be tilted
20 degrees on its axis to allow the operator to select the best viewing
angle.
The Over/Under/Accept display consists of 45 segments, 19 Over (Yel-
low), 19 Under (Red), and 7 Accept (Green), plus the legend block for
each. In operation, only one segment and the legend illuminate for the
Accept range. If the weight on the scale is in the Over or Under range, an
increasing number of segments, radiating outward from the center,
“illuminate’’ in proportion to the amount the weight is over or under target
weight. The Over or Under legend also illuminates.
The Center-of-Zero illuminates when the scale is within ±¼
division of reference pushbutton zero.
The N illuminates to indicate that tare is in effect.
The Weight display consists of six 7-segment digits and accompanying
decimals. The appropriate unit of measure for the displayed weight is
illuminated to the right of the weight display.
There are ten membrane type control keys on the face of the display
housing.
UNDER/OVER/ACCEPT Used as selection keys during operation.
TEST Initiates the display test sequence.
ZERO Zeros the scale, and returns scale to
normal operation from any operator setup
function.
SETUP Places the scale in the setup mode.
PRINT Initiates the transmission of serial data to
a peripheral device.
UNITS Used to select unit of measure for the
weight displayed.
TARE Enters a pushbutton tare value, and used
to enter a numerical tare value.
GROSS Displays gross weight when the scale is in
net mode.

Software Options
The 3275 Checkweigher can be modified with optional software. If you do not
have any of these options installed on your 3275 you may disregard the last
portion of this manual.
If you have one of these software options, follow the directions for your
particular option. The optional programs available are:
• Multiple Setup
• Multiple Setup with Manual Recall
• Standard Deviation
• X-Bar R
• LB-OZ
• Percent
Each of these programs is explained on the following pages. Some of these
programs require additional hardware. Consult the instructions that come
with each program or the 3275 Service Manual.
This program can only be operated if the Multiple Setup Option is installed
and if you use the optional Remote Keypad.
The Multiple Set Up option allows you to enter and store six weight param-
eters in up to ninety-nine different memory channels. You may recall any
memory channel and its stored weight parameters by entering a two digit
channel number on the remote keypad thus adding supervisor security to
the settings.
This program will extend power up initialization time to approximately 60
seconds. During initialization, the display will be blank until it is finished.
Current parameter settings are automatically restored following a power loss
and subsequent power up.
The parameters that can be programmed and saved are
• Target Weight
• Tare Value
• Over Tolerance Value
• Under Tolerance Value
• Over Alarm Value
• Under Alarm Value
The Setup currently installed can be identified at any time by pressing TEST.
The channel number will be displayed temporarily as “SEt xx”. If no Setup is
in use, the display will show “SEt 0”.
If an invalid Setup channel number (1-99 are acceptable) is entered, the
scale will display "Error" momentarily then return to the last setup.
To save Setup values:
1. Set target weight, tare, and
tolerance values as explained on
pages 4-6 of this manual.
2. Press ALT and decimal (.) on
the remote keypad. . . The display shows “Alt.”.
