1.0 INTRODUCTION

This instrument is a precision digital indicator using the latest Sigma -Delta A/D technology to ensure fast and
accurate weight readings.

The setup and calibration of the instrument are digital, with a non-volatile security store for all setup parameters.
The instrument may be operated from either 4 AA batteries or a DC power source from 12V to 24V. There is a soft

power on/off function that retains memory of its state. Once an instrument is turned on it will automatically start up
again if the external power is interrupted.

The instrument is fitted with GSE -LINK communications as standard. This allows a temporary isolated
communications link to be established with a PC and enables software upgrades and the use of computerized
setup and calibrat ion via the Viewer software. Refer to GSE-LINK (Optional) section 3.10 for more information.

Figure 1: Weight Indicator

1.1 Overview

This instrument provides the ZERO and TARE functionality as well as providing more setup options (e.g. serial and
setpoints) and printing functionality.

It also supports special functions (e.g. peak -hold, live weight (livestock) averaging, counting, etc.), via the user
definable <FUNCTION> key. It is equipped with an NVRAM store to ensure day -to-day operating settings (e.g.
ZERO, TARE, CLOCK, etc.), are retained when power is removed.

This instrument has two isolated transistor outputs with status display on the front panel as well as the RS -232
communications port that can be used for printer driving or connection to a remote display or PC. There is a built-in
clock for date-stamping printed outputs.

3.0 INSTALLATION

3.1 Introduction

The following steps are required to set up the indicator.

• Inspect indicator to ensure good condition.

CF 147 2 version 1.1

• Use connection diagrams to wire up load cell, power and auxiliary cables as required.

• Use the drill hole template provided for hole locations.

• Connect Power to indicator and press <POWER> key to turn the instrument On.

• Refer to the Setup section 7.0 for information on configuring and calibrating the instrument.

• To turn instrument Off press and hold <POWER> key for three seconds (until display blanks).

3.2 General Warnings

• Indicator not to be subject to shock, excessive vibration or extremes of temperature (before or after installation).

• Inputs are protected against electrical interference, but excessive levels of electro -magnetic radiation and RFI

may affect the accuracy and stability.

• The instrument should be installed away from any sources of excessive electrical noise.

• The load cell cable is particularly sensitive to electrical noise and should be located well away from any power

or switching circuits.

• For full EMC or for RFI immunity, termination of cable shields and correct earthing of the instrument is
essential.

• Indicator and load cell cable are sensitive to excessive electrical noise. Install well away from any power or
switching circuits.

3.3 Electrical Safety

• For your protection all electrical hardware must be rated for environmental conditions of use.

• Pluggable equipment must be installed near an easily accessible power socket outlet.

• To avoid the possibility of electric shock or damage to the instrument, always switch off or isolate the

instrument from the power supply before maintenance is carried out.

3.4 Cleaning

• To maintain the instrument, never use harsh abrasive cleaners or solvents. Wipe the instrument with a soft
cloth slightly dampened with warm soapy water.

3.5 Panel Mount Template

Use the panel mount template for drill hole locations. The template indicates positions for the two 4mm mounting
screws through the panel. Also displayed on the template is the position of the rectangular hole that should be cut
to allow for the connection of cables. The drilling template supplied with the indicator allows for front or rear
machining of the panel.

3.6 Cable Connections

All cable connections are made to the rear of the instrument using screwless terminals. Wires must be stripped of
insulation by at least 10mm. To install, depress the orange lever beside the terminal required and push wire into the
hole. Release the lever and pull gently on the wire to ensure it is securely trapped in the termi nal. It is not
necessary to tin the ends of the wire with solder or to add crimp ferrules to the wires; however, these techniques
are also compatible with the terminals and may ultimately make for a neater job.

Figure 2: Cable Connections

3.7 DC Power (DC PWR +, DC PWR –)

CF 147 3 version 1.1

The DC supply need not be regulated, provided that it is free of excessive electrical noise and sudden transients.
The instrument can be operated from a high quality AC wall transformer as long as there is sufficient capacity to
drive both it and the load cells.

3.8 Load Cell Connection

3.8.1 Load Cell Signals and Scale Build

Very low output scale bases may be used but may induce some instability in the weight readings when used with
higher resolutions. Generally speaking, the higher the output, or the lower the number of divisions, the greater the
display stability and accuracy.

The instrument can display the milliVolt-per-Volt reading that can be used to check scale base signal output levels.
For more information, refer to SCALE (Scale Base Test Display) section 7.4.8.
The instrument may be connected for either 4-wire or 6–wire operation. To correspond with the actual cabling
installation the instrument must be configured in setup to the correct setting. For more information, refer to CABLE
(4-Wire or 6-Wire) section 7.4.1.

3.8.2 4-Wire Connection

The minimum connectivity requirements are the connection of four wires (i.e. Excitation + and – along with Signal +
and –). Internally the instrument has a precision analog switch that can be used to connect the Sense + and – lines
directly to the Excitation + and – lines.

Any addition to the load cell manufacturer's cable length using 4-wire connection is only recommended for short
cable runs. Where long additions to cable lengths are neede d, a 6-wire extension is required.

The BUILD: CABLE option must be set to 4 to allow for 4-wire connection. Refer to CABLE (4-Wire or 6- Wire)
section 7.4.1.

Figure 3: 4-Wire Connections

3.8.3 6-Wire Connection

The excitation and signal lines are connected the same as for a 4-wire installation. The extra two wires (Sense +
and –) should be connected to the Excitation + and – lines as close as possible to the load cell itself. Typically
these connections are made in a load cell termination box.

The BUILD: CABLE option must be set to 6 (the default) to allow for 6-wire connection. Refer to CABLE (4- Wire or
6-Wire) section 7.4.1.

CF 147 4 version 1.1

Figure 4: 6-Wire Connections

3.9 Auxiliary Connections

This section provides diagrams to illustrate the terminal connections.

3.9.1 RS-232 Serial

• Direct Personal Computer Link (RXD, TXD, GND)

Figure 5: RS -232 - Instrument to PC using COM Port (DB9)

Figure 6: RS -232 – Instrument to PC using COM Port (DB25)

• Printer Connections (RXD/TXD, GND and DTR)

Figure 7: RS -232 – Instrument to Printer (DB25)

• Remote Display (TXD, GND)

The remote display documentation should be referred to for connection details. Connect TXD to RXD and GND to

GND on the remote display.

3.9.2 Remote Input

The indicator requires a voltage free contact between TXD and RXD to enable the remote input (ie.
SPEC:REM.FN). Note: The remote input will not function when in setup or when using the opto-LINK.

CF 147 5 version 1.1

Figure 8: Remote Input

3.9.3 Outputs

The output drivers for the instrument are isolated open emitter transistor drives that are capable of driving up to a
total of 300mA. This configuration allows for the direct connection of the instrument outputs to most PLC types.

The voltage applied to the COM terminal appears on the output lines (i.e. OUT1 and OUT2) when the outputs are
active (e.g. to connect to a PLC connect +24V to the common terminal). The outputs can then be connected directly
to PLC inputs so when activated the PLC will see the 22V signal (approx. - the exact switch loss will depend on
loading of the output).

To drive external loads (e.g. relays), connect the relay coil positive supply to the output common and the output line
directly to one side of the relay coil. Connect the other end of the relay coil to the negative supply. It is
recommended that fly-back diodes or transient suppressors be fitted across relay coils to limit switching noise.

Figure 9: Instrument Outputs to Drive Relay

Figure 10: Instrument Outputs to Drive PLC

3.10 GSE-LINK (Optional)

CF 147 6 version 1.1

A temporary infrared communications link can be established between the instrument and a PC using an optional
GSE-LINK cable. The optional GSE-LINK cable can be used to transfer setup and calibration information from a PC
(e.g. to be stored for later use and/or transferred to other ins truments). It can also be used to download software
upgrades to the instrument from a PC.

The PC end of the GSE -LINK cable is a standard female DB9 connector. The instrument end of the cable consists
of an infrared transceiver, which attaches to the left side of the instrument display. To facilitate a quick and simple
connection, the infrared transceiver is secured in place by a permanent magnet located within the head of the GSE­LINK.

Refer to GSE-LINK Activation section 5.7.1 for more information.

WARNING

The GSE-LINK head contains a strong magnet and care should be taken with its proximity to electronic
media (e.g. credit cards, floppy disks, etc.) and/or other electronic instrumentation.

Figure 11: GSE-LINK Attachment

3.11 Connecting Shields

To obtain full EMC or for RFI immunity, cable shields MUST be connected to the earth lug on the rear of the
instrument.

Figure 12 illustrates an example of possible connections. Also shown are the connecting cables restrained using
cable ties fastened around the cable strain relief anchors.

Figure 12: Cable Shield Connection

3.11.1 Cable Shield Connection and Earthing

• Care should be taken when connecting shields to maximize EMC or RFI immunity and minimize earth loops
and cross-talk (interference) between instruments.

• For full EMC or for RFI immunity, termination of the cable shields at the earth lug is very important. The earth
lug of the instrument must be separately connected to ground potential via a reliable link.

• The instrument should only be connected to earth via a single reliable link to avoid earth loops.

• Where each instrument is separately earthed, interconnecting cable shields should be connected at one end

CF 147 7 version 1.1

only.

• Caution: Some load cells connect the cable shield directly to the load cell (and therefore the scale base).
Connection of the load cell cable shield in this situation may be site specific.

3.12 Regulatory Sealing Requirements

To comply with regulatory sealing requirements for each instrument, (i.e. to ensure instruments are not accidentally
or deliberately tampered with), it is important that proper sealing procedures be adhered to. Refer to Sealing
section 12.2 for more information.

5.0 BASIC OPERATION

In the most basic configuration, the instrument provides a simple weight readout.

5.1 Display and Controls

Figure 14: Display and Controls Illustration

5.1.1 Front Panel: Visual Display

The front panel has a six-digit LCD display. Figure 14 shows the main elements of the front panel.
The instrument has various main display sections for the visual output of weight information. Each display section is
described below.

• Weight Display
The Weight Display indicates the weight readings, setup information, errors and warnings.

• Units Display
The Units Display shows the units of the weight reading as either grams (g), kilograms (kg), pounds (lb), tons (t)
or none ( ). If the instrument is set up for counting the units display will show pieces (p).

• Status Annunciators
Status annunciators show the following:

Table 1: Status Annunciators
SYMBOL NAME DESCRIPTION

ZERO Visible when the gross reading is within ± ¼ of a division of true zero.
NET Visible when the displayed reading represents Net weight.

CF 147 9 version 1.1

MOTION Visible when the displayed reading is not stable.
OVER Visible when the setpoint weight is over the setpoint target.
UNDER Visible when the setpoint weight is under the setpoint target.

ZERO BAND
HOLD Visible when the displayed reading is held.

LOW
BATTERY

Visible when the displayed weight is within the zero 'dead' band setting. (The zero
band symbol shows near the top right corner of the display.)

Visible when battery voltage is too low and batteries need replacing or recharging.
(The low battery symbol shows in the top right corner of the display.)

When in Setup the editing annunciators are shown to identify the function of the front panel keys (i.e. GRP, ITM,

SEL, EDT and OK). For more information refer to Editing Annunciators section 4.1.

5.2 Operation Keys

The instrument has the following oper ation keys:

• POWER
Primary Operation Keys

• ZERO

• TARE

• GROSS/NET

• PRINT

• FUNCTION (user defined)

Each of the primary operation keys
has two separate functions.

5.2.1 Primary Function

A single press of each key triggers the weighing operation printed on it. The instrument allows individual keys to be
disabled in the setup. All keys are enabled at the factory, but some keys may have been intentionally disabled
(locked) during installation. If a key has been locked, a long beep sounds when it is pres sed. If however, the key
beeps normally, but does not appear to trigger the desired action, it is waiting for the weight reading to settle before
the action can proceed.

5.2.2 Editing Function

Available during digital setup and calibration. This function is displayed using the editing annunciators above each
key. Refer to Editing Annunciators section 4.1.

5.3 Stability Considerations

Once a <ZERO> , <TARE> or <PRINT> key is pressed the instrument waits for a stable valid reading before
performing the assoc iated operation. If the weight readings remain unstable or invalid due to some diagnostic error
for longer than 10 seconds, the operation is cancelled and the STABLE ERROR message is displayed.

To improve the stability of the weight reading, increase the filtering or relax the motion detection criteria. Refer to
FILTER (Reading Average) section 7.4.2 and MOTION (Motion Detection) section 7.4.2 for more information.

5.4 POWER Key

The <POWER> key is used to turn the instrument on and off. To initially turn the instrument on, press and
hold the <POWER> key. The display will show the following:

• Display segments will light and then clear.

• Software Version (e.g. V1.0).

• Calibration Counter (e.g. C.00010). Refer to Calibration Counter section 6.5 for more information.

• The current weight will then display.

To turn the instrument off, press and hold the <POWER> key for three seconds. The instrument will display OFF
followed by the three -second countdown.
When using batteries the backlight will automatically turn off to conserve power after a short period of inactivity. A
short press of the <POWER> key will turn the backlight on again. Refer to B.LIGHT (Backlight Operation) section

7.4.4 for more information.

CF 147 10 version 1.1

Note: The <POWER> key can be locked to prevent the ins trument being turned off from the front keypad. Refer to
KEY.LOC (Front Panel Key Locking ) section 7.4.4 for more information.

5.4.1 Automatic Operation

The <POWER> key on the instrument is unusual in that it has a memory function associated with it. This means
that the state of the power setting is remembered even if external power is interrupted. It is therefore possible to
turn the instrument on in the safe knowledge that it will operate whenever external power is available and will not
need to be manually turned on again if the power is interrupted.

5.5 ZERO Key

When an empty scale has drifted away from a true zero reading, this key is used to perform a zero
adjustment on the scale display. The zero adjustment is stored when power is removed and is re-used
when next powered up.

The amount of weight that may be cancelled by the <ZERO> key is limited via an item in the Setup of the
instrument. Refer to Z.RANGE (Allowable Zero Operating Range) section 7.4.2 for more information.
Long Press: When the indicator is set to Industrial mode a long press of the <ZERO> key will remove any stored
zero adjustment. Refer to Industrial vs. OIML and NTEP Modes, section 6.4, for more information on modes.

5.6 TARE Key

This key is used to temporarily set the scale to zero (such as cancelling the weight of a carton before
performing a filling operation). The display will show the Net weight and the NET annunciator will be lit.

The <TARE> key can operate in all modes (i.e. Industrial, OIML and NTEP). Refer to Industrial vs. OIML
and NTEP Modes section 6.4 for more information.
The weight tared is deducted from the allowable range of the scale, reducing the maximum weight that can be
displayed. The tare adjustment is stored when power is removed and is re-used when next powered up.

5.7 GROSS/NET Key

This key toggles the weight display between the Gross weight and the Net weight (provided that a Tare has
previously been acquired using the <TARE> key).

5.7.1 GSE-LINK Activation

This feature is used to temporarily connect a PC to the instrument for calibration and setup purposes. A long press
of the <GROSS/NET> key will toggle the GSE -LINK infrared communications On/Off. When the GSE-LINK has
been (enabled) the following will occur:

• The instrument briefly displays the prompt rin-L.

• The editing annunciators (i.e. GRP, ITM, etc.) will flash for up to five minutes while the instrument searches for

activity. During this period, the instrument also disables the RS -232 communications.

• Activity Located: If the instrument is successful in locating activity, the editing annunciators will continue to
flash during the entire period of communications.

• No Activity Located: If the instrument fails to locate activity, the GSE-LINK will be disabled and the editing
annunciators will stop flashing. The instrument will also revert back to the normal RS -232 communications (i.e.
the SERIAL:TYPE setting will be re-activated).

5.8 PRINT Key

If a printer or computer has been attached to the instrument and the manual print function has been
selected, the <PRINT> key will trigger an output of the current weight reading. The PRINT prompt is

displayed while waiting for the printer to accept data. If the printer is offline the PRINT prompt will remain
for a maximum of 10 seconds before the oper ation is cancelled. Each weight printed is automatically added to an
internal Total Weight.

Long Press: A long press of the <PRINT> key will print the total. The total weight is then cleared automatically.

5.9 FUNCTION Key

CF 147 11 version 1.1

When leaving the factory, the <FUNCTION> key is blank and has no primary function preprogrammed.
The primary function of this key can be selected from a number of different functions including peak -hold,

counting, etc. Refer to Special Functions section 11.0 for details of the available functions. Each primary
function has an associated overlay sticker that should be applied to the <FUNCTION> key to label the function of
the key.

Long Press: A long press of the <FUNCTION> key may be used for certain functions depending on the primary
function of the key.

6.0 CONFIGURATION ISSUES

6.1 General Setup Information

Configuration and calibration can be performed entirely from the front panel, using the digital setup facility. When
Full Setup is used, all menu items are accessible and care must be taken to ensure no accidental changes are
made to calibration and trade settings. In addition, there is also Safe Setup that provides restricted access. This
setup method ensures that only settings that are not calibration or trade sensitive can be changed.
Full and Safe Setup can be passcode-protected to prevent unauthorized or accidental tampering. If the scale has
been passcode -protected, the setup menus cannot be accessed until the correct code has been entered.

6.2 Basic Weighing Terminology

The following terms are used throughout the setup procedure. Knowledge of these basic weighing terms is
beneficial in setting up and calibrating the instrument.

Note: Descriptions of these and other terms used in this manual are listed in the Glossary Terms section 12.6.

Term Definition

Units Units of measurement (kilograms, tons, pounds, etc.).
Full Scale Total change in weight between zero gross load and full capacity gross load.
Resolution or Count -by Smallest change in weight units that the display can show.
Total Number of
Graduations
Division A single graduation.

Example

This example provides a check to ensure the capability of an indicator to read a stable weight on extremely small
divisions compared to the load cell capacities.
The check is to find out what the micro-Volt per division is and then compare this to GSE Scale System’s
specification. If GSE Scale System’s specification is smaller than the calculated value, the unit is within the
requirements of operation.
Note: The capability of an indicator may be different than the trade approval limit of the micro-Volt per division.

A 10,000lb 2.0mV/V load cell is used in an application requiring a 5000lb full scale, with weight displayed in 5lb
increments.

The values are:

• Units = lb

• Full Scale = 5000

• Count-by = 5

Calculating the total
number of
graduations:
Signal voltages can be calculated as follows:
Calculating the full
scale signal (load cell):

Maximum number of display steps between zero gross load and full capacity gross
load. It is equal to full scale divided by the count -by.

6.3 Filtering Techniques

There is a trade off between noise filtering and the step-response time of the system. The step -response is defined
as the time between placing a weight on the scale and the correct stable weight reading being displayed. This does
not affect the number of readings per second that are taken. It simply defines the amount of time that is required to
determine a final weight reading.

The FILTER setting in the instrument setup shows the amount of time over which the averaging is taken.
Increasing the averaging time will result in a more stable reading but will extend the time it takes the instrument to
settle to a final reading. Refer to FILTER (Reading Average) section 7.4.2.

6.4 Industrial vs. OIML and NTEP Modes

The instrument may be operated in Industrial, OIML or NTEP mode. (Note: For NSC requirements use the OIML
setting.) The OIML and NTEP modes restrict certain aspects of the operation of the instrument to ensure
compliance with the respective trade certified standards. For more information refer to the Calibration Counter

section below and also to the USE (Scale Use) section 7.4.2 for setup information. The following table lists the
operation differences for each of these modes.

Table 2: Industrial vs. OIML and NTEP Modes

Overload 105% of full scale Full scale +9 divisions 105% of full scale
Tare No restrictions on Tare Tare values must be > 0 Tare values must be > 0 and

rounded to the nearest graduation

Test Modes Unlimited time allowed Limited to five seconds Limited to five seconds

6.5. Calibration Counter

Within Setup there are a number of critical steps that can affect the calibration and/or legal for trade performance of
the instrument. If any of these steps are altered, the trade certification of the scale could be voided.

The instrument provides built-in calibration counter(s) to monitor the number of times the critical steps are altered.
The value of a counter is stored within the instrument and can only be reset at the factory. Each time a critical step
is altered, the counter will increase by one. Whenever the instrument is powered up, or setup mode is entered/
exited, the current value in the counter is displayed briefly (e.g. C00010).

Note: When the Scale Use is set to NTEP two counters will display. Refer to USE (Scale Use) section 7.4.2 for
setup information. The table below describes when the counter(s) will increm ent for Industrial, OIML or NTEP
modes.

Industrial OIML NTEP

The Calibration Counter
increments when trade
critical settings, marked
with , are changed. An
example of the counter is
C.00019.

CF 147 13 version 1.1

The Calibration Counter
increments when trade
critical settings, marked
with , are changed. An
example of the counter is
C.00019.

The Calibration Counter increments when trade critical
settings in the Calibration (CAL) menu, marked with , are

changed. An example of the counter is C.00010.
The Configuration Counte r increments when other trade

critical settings (i.e. not in the CAL menu), marked with ,
are changed. An example of the counter is F.00009.

The value(s) of the counter(s) is written on the tamperproof trade label on the front of the indicator for trade-certified
applications and functions as an electronic seal. If any legal for trade settings are changed on the instrument, the
current value of the calibration counter will be different from the recorded value and the seal is broken. In this
manual, items marked with indicate that the setting is legal for trade critical settings.

6.6 Passwords

The instrument has two levels of passcodes to provide a security lock on accessing Setup via the keypad.

• Full Setup Passcode

• Safe Setup Passcode

The Full Setup passcode can also be used to access Safe Setup.

6.6.1. Full Setup Password

Setting a passcode for Full Setup restricts any access to Full Setup. Refer to FULL.PC (Full Security Passcode for
Digital Setup) section 7.4.4.

6.6.2. Safe Setup Password

Setting a passcode for Safe Setup restricts access to Safe Setup functions. Refer to SAFE.PC (Safe Security
Passcode for Digital Setup) section 7.4.4.

6.6.3. Setup Lock-Out

If an attempt is made to enter Full or Safe Setup using an incorrect passcode, the instrum ent will respond with the
message ENTRY DENIED and then the user will be returned to normal operating mode. A passcode counter has
been set so that only three failed attempts can be made to access Full/Safe Setup. On the fourth attempt the user
will be 'locked out' of Full/Safe setup. Should this occur, the ENTER PASS prompt will not display, but instead the
ENTRY DENIED message displays and returns the user to the normal operating mode.

To rectify this issue the instrument must be turned off. When the ins trument is turned back on the passcode counter
is reset to zero (allowing the user to enter the correct passcode).

7.0 SETUP

The instrument digital setup facilities provide the means to configure and calibrate the instrument.

7.1 Accessing Setup

There are two methods to access the Setup area. For further details of menu items available in each setup mode,

used to cycle through the available items. The <SEL> key is then used to edit the item.

7.4 Setup Menus

The following sections describe the setup parameters of each of the Groups and Items in Setup.

7.4.1 BUILD (Scale Build)

Settings within this Group are used to configure the indicator to suit the current application. It is important to fully
set the options within this group before calibration is attempted. Later changes to items within this group may
invalidate the current calibration data.

• DP (Decimal Point Position)
Sets the location of the decimal point on the display. To avoid confusion, set this parameter first so that all other
weight related values are displayed with the decimal point in the correct position.

• Can be set from 000000 (none) to 0.00000

• Default: 000000

• CAP (Maximum Capacity)

Sets the nominal maximum capacity (or full scale) of the scale. This is set in weighing units (e.g. lb, t, etc.), with
the decimal point in place. For example, if a scale is to weigh 500.0 lb in 0.5 lb increments, CAP is set to 500.0,
and RES is set to 5.

• Range: 000100 to 999999

• Default: 003000

• RES (Count -by Resolution)

stabilize the display at the expense of rapid response to sudden weight changes.

• Options are: NONE, 0.2, 0.5, 1.0, 2.0, 3.0, 4.0 (time in seconds)

• Default: 0.5 (seconds)

• MOTION (Motion Detection)

Sets how much weight variation over a defined time period is allowed before the displayed weight is deemed to
be unstable. This value is displayed as weight change (0.5 or 1.0 graduations) per second. When set to OFF,
the Motion Detection is ignored and ZERO, TARE and PRINT actions are instantaneous.

• Options: OFF, 0.5-1.0, 1.0-1.0 (graduations per second)

• Default: 0.5-1.0 (0.5 graduations per second)

• INIT.Z (Initial-Zero on Startup)

This function can be used to automatically ZERO the indicator during power -up. The amount of weight that can
be zeroed is limited to +/– 10% of full scale.

• Options are: ON or OFF

• Default: OFF

• Z.TRAC (Zero Tracking Sensitivity)

Zero tracking allows the display to adjust for minor changes in the zero balance of the scale. When enabled,

This setting restricts the range over which the Zero functions can operate.

• Options are: -2_ 2, -1_ 3, -20_20

• Default: -2_ 2 (–2% to +2%)

• Z.BAND (Zero 'Dead' Band)

This is an adjustable margin either side of true zero that defines the zero 'dead' band. The zero 'dead' band is
used by the automated functions to determine zero load (e.g. a setting of 4 specifies that readings between –

4.5 and 4.5 are considered to be zero).
When the displayed weight reading is within this band the instrument displays the zero band annunciator.
Refer to Status Annunciators section 5.1.1.

• Settable over the full weight range. Always enter a number in multiples of display units. Refer to RES (Count -

by Resolution) section 7.4.1 for more information.

7.4.8 TEST (Special Test Functions)

Items within this Group allow access to the testing routines for the instrument. With these routines the scale base
output can be monitored and the inputs and outputs can be tested.

• SCALE (Scale Base Test Display)
Verifies the correct load cell capacity and/or load cell wiring is used. It sets up the instrument as a simple test
meter to measure the load cell signal output. The display reads in millivolts-per-Volt, factory calibrated to 0.1%
worst case. When accessing this item, initially there should be no weight on the scale. In OIML or NTEP
modes, this display is only active for five seconds before returning to the menu.

• FRC.OUT (Force Outputs)
Forces each of the output drivers in turn. All outputs turn OFF when leaving this step. The <EDT> key will
advance through each output (i.e. ON.1 and ON.2). Pressing <OK> will turn all outputs off and exit the test.

7.4.9 FACTRY (Factory Adjustment Menu)

• DEFLT (Restore Factory Settings Except for Calibration and Build)
Restores all settings in the digital setup, which are not calibration critical back to the original new settings
installed at the factory. The main use of this routine is to completely reset an instrument that is being installed
on a different scale. The instrument will prompt with Cont. N. Press <EDT> to change to Cont. Y and <OK> to
continue. When Cont. Y has been chosen the instrument will display DONE to indicate that the operation has
been completed.
Restoring the factory options does not affect the calibration. To reset the calibration to factory condition
CAL:FAC.CAL must be used. Refer to FAC.CAL (Restore Default Factory Calibration) section 7.4.3. This
menu item is only available when in Full Digital Setup mode.

7.4.10 – End – (Leaving Setup)

Refer to Exiting Full or Safe Setup section 7.2.

8.0 CALIBRATION

The calibration of the indicator is fully digital. The calibration results are stored in permanent memory for use each
time the instrument is powered up.

Note: Some of the digital setup steps can affect calibration. The BUILD and OPTION settings MUST be

CF 147 21 version 1.1

configured before calibration is attempted.

To perform a calibration, when in Full Setup select the CAL Group using the <GRP> key.
The calibration program will automatically prevent the instrument from being calibrated into an application outside

of its specification. If an attempt is made to calibrate outside of the permitted range, an error message will display
and the calibration will be abandoned. Refer to Error Messages section 12.4.

The instrument has a wide -range ADC. The non-trade calibration range of the instrument extends well beyond the
Trade approved range.

Note: It should not be assumed that just because the instrument has successfully calibrated a scale, that
the scale is correct for trade use. Always check the scale build against the approval specification.

8.1 Performing a Digital Calibration with Test Weights

Figure 15: Chart - Zero and Span Points to Interpolate Weight from Load Cell

The Zero setting (CAL:ZERO) specifies a gross zero point for the scale. The Span setting (CAL:SPAN) specifies a
second point (preferably close to full scale) used to convert the A/D readings into weighing units (e.g. kg). Select
either of the Zero (CAL:ZERO) or Span (CAL:SPAN) calibrat ion items. It is important that an initial Zero calibration
is performed before any SPAN calibrations. The chart shown here demonstrates how the zero and span points are
used to interpolate a weight reading from the load cell reading.

Note: Calibration points (Zero, Span and Linearization) must be spaced by at least 2% of Full scale from
each other.

8.1.1 ZERO (Zero Calibration Routine)

• Press the <SEL> key to start. The display will show the current weight. Remove all weight from the scale
structure.

• Press <SEL>, <EDT> or <OK> to execute a Zero Calibration. The display will show Z.in.P to indicate that zeroing
is in progress. When the process is complete the display will return to weight to allow the zero to be checked.

• Press the <ITM> key to leave the Zeroing routine or press <SEL>, <EDT> or <OK> to repeat the operation.

8.1.2 SPAN (Span Calibration Routine)

• Press <SEL> or <OK> to start. The display will show the current weight.

• Add the calibration test mass to the scale. The minimum accept able span calibration weight is 2% of the scale
range. A weight this small may limit calibration accuracy. The closer the test weight is to full scale the better the
accuracy.

• Press <SEL> or <OK> to show the calibration weight value. Change this to the correct calibration weight using the
<SEL> and <EDT> keys.

• Press <ITM> or <OK> to trigger the Span Calibration routine. The display will show S.in P to indicate that
spanning is in progress. When the process is complete the display will return to weight to allow the new weight
reading to be checked.

CF 147 22 version 1.1

• When the Span Calibration is complete, press the <ITM> key to leave the Spanning routine or press <SEL>,

<EDT> or <OK> to re-edit the calibration weight and repeat the operation.

8.2 Performing a Calibration with Direct mV/V Entry

In applications where test weights are not easily available, it is possible to calibrate the instrument directly by
entering the mV/V signal strength at Zero and full scale Span. The Direct Zero setting (CAL:DIR.ZER) specifies a
gross zero point for the scale. The Direct Span setting (CAL:DIR.SPN) specifies the mV/V signal strength
corresponding to an applied mass equal to the full scale reading. This calibration technique is not compatible with
linearization. Clearly the accurac y of this type of calibration is limited to the accuracy of the direct mV/V data.

8.2.1 DIR.ZER (Direct Zero Calibration Entry)

• Press the <OK> key to start. The display will show the current weight.

• Press the <OK> key to enter the Direct Zero setting. Change the mV/V setting to the correct value for Zero using
the <SEL> and <EDT> keys.

• Press the <OK> key to store the new zero calibration. When the process is complete the display will return to
weight to allow the new weight reading to be checked.

• Press the <ITM> key to leave the Direct Zero routine or <OK> to repeat the operation.

8.2.2 DIR.SPN (Direct Span Calibration Entry)

• Press the <OK> key to start. The display will show the current weight.

• Press the <OK> key to enter the Direct Span setting. Change the mV/V setting to the correct value for the full
scale signal strength, using the <SEL> and <EDT> keys.

• Press the <OK> key to store the new span calibration. When the process is complete the display will return to
weight to allow the new weight reading to be checked.

• Press the <ITM> key to leave the Direct Span routine or <OK> to repeat the operation.

8.3 Using Linearization

This section provides instructions on the use of the linearization. Linearization is used to approximate the weight
output to a non-linear scale. The chart below shows a non-linear characteristic for the load cell output. From the
chart, it can be seen that the trace with no linearization applied is a poor approximation to the real characteristic. By
applying on e or more linearization points, more accurate weight readings can be achieved.

To perform a linearization, a calibration of the zero and full scale span points must have been performed. Both the
zero and full scale calibration points are used in the linea rization of the scale base. These two points are assumed
to be accurately set and thus have no linearization error.

Figure 16: Chart - Non-Linear Characteristic for Load Cell Output

A maximum of five linearization points can be set independently between zero and full scale. Unused or unwanted
points may also be cleared. The maximum correction that can be applied using a linearization point is + / - 2%.

8.3.1 ED.LIN (Edit Linearization Points)

CF 147 23 version 1.1

• Press the <SEL> key to step through the list of points. Eac h point is shown as Ln.ppp where n is the point
number (1 to 5), and ppp is the approximate percentage of full scale where the linearization is applied. For
example, L1.050 indicates that linearization point one is active and was entered at about 50% of full scale. Unused
linearization points are shown with a row of dashes (e.g. L2. - - -).

• Press <OK> to change the linearization point selected or press <ITM> to exit without making any changes.

• After pressing <OK>, the current weight reading is display ed. Add the calibration test mass to the scale. The
closer the test mass is to the point of maximum error in linearity the more effective will be the correction. Press
<OK> to enter a corrected weight value for this point or <ITM> to exit without making changes.

• Use the <SEL> and <EDT> keys to enter the correct value of the calibration weight being used.

• Press the <OK> key to trigger the linearization routine. The display will show L.in P to show that linearization is in
progress. When the process is complete the display will show the weight to allow the new weight reading to be
checked before returning to the menus. Press <ITM> to leave the routine or <OK> to repeat the operation.

CF 147 24 version 1.1

8.3.2 CLR.LIN (Clear linearization)

• Press the <SEL> key to step through the list of points. Each point is shown as Ln.ppp where n is the point
number (1 to 5), and ppp is the approximate percentage of full scale where the linearization is applied. For
example, L1.050 designates that linearization point one is active and was entered at about 50% of full scale.
Unused linearization points are shown with a row of dashes (e.g. L2. - - -).

• Press <OK> to choose the linearization point to clear. The indicator will prompt to continue with CONT. N. Press

<ITM> to switch between Cont. N (No) and Cont. Y (Yes). The <OK> key is used to accept your choice. When
Cont. Y has been chosen the cleared linearization point then displays (e.g. L1. - - -).

• Press <ITM> to return to CLR.LIN.
Note: All linearization points are cleared by restoring the default calibration of the instrument. The zero and span

settings are also cleared by this process.

9.0 SERIAL OUTPUTS

The instrument can support the optional temporary GSE-LINK connection. In addition, there is a single bidirectional
RS-232 output. This provides a number of serial output options allowing communications with external devices
such as printers, computers, PLCs or remote displays. Refer to GSE-LINK Activation section 3.10. For wiring
connections and pinouts, refer to Auxiliary Connection section 3.9.

The serial available functions include:

• Automatic Weight Output (two formats available)

• Network Communications

• Master / Slave

• Printing

All serial output options are enabled and configured using the serial communications options in the digital setup
procedure. Refer to SERIAL (Serial Communications Options) section 7.4.5.

The instrument computer communications can range from simple automatic streamed output, through to a
command-response system. In addition to the GSE-LINK, the instrument can be programmed and calibrated via the
RS-232 serial port. The calibration counter is incremented when the calibration related steps are accessed via RS ­232, the serial port or the GSE -LINK. This means that calibration via the serial port or GSE-LINK cannot be carried
out without affecting the certification of a trade installation.

9.1 Automatic Weight Output

The automatic output is normally used to drive remote displays, a dedicated computer, or PLC communications.

Auto Weight Format String

The weight format string may be set to the following formats:

Format Description
AUTO1 <STX> <SIGN> <WEIGHT(7)> <STATUS> <ETX>
AUTO2 <STX> <SIGN> <WEIGHT(7)> <S1> <S2> <S3> <S4> <UNITS(3)> <ETX>

Where

• STX: Start of transmission character (ASCII 02).

• ETX: End of transmission character (ASCII 03).

• SIGN: The sign of the weight reading (space for positive, dash (-) for negative).

• WEIGHT(7): A seven character string containing the current weight including the decimal point. If there is no

decimal point, then the first character is a space. Leading zero blanking applies.

• STATUS: Provides information on the weight reading. The characters G/N/U/O/M/E represent Gross / Net /
Underload / Overload / Motion / Error, respectively.

• UNITS(3): A three character string, the first character being a space, followed by the actual units (e.g. ^kg or
^^t). If the weight reading is not stable, the unit string is sent as ^^^.

• S1: Displays G/N/U/O/E representing Gross / Net / Underload / Overload / Error, respectively.

CF 147 25 version 1.1

• S2: Displays M/^ representing Motion / Stable, respectively.

• S3: Displays Z/^ representing center of Zero / Non-Zero, respectively.

• S4: Displays - representing single range.

• Printing

The instrument has a single fixed printing format that is as follows:

000048 06/05/2003 15:10

121.4 lb G

The first line contains a six digit sequential number that is automatically incremented with each printing, up to a
maximum of 999999. The first line also contains the current date and time, printed in the selected format. The
second line shows the displayed reading, units and G for Gross or N for Net.

If counting is active, the printout has a third line for the counting information (p for pieces) as follows:

164 p

Whenever a new sample is taken when counting, the instrument prints the sample as in the following format:

SAMPLE: 100 p = 50.0 lb

In addition to the printout, the instrument adds the weight and pieces printed to the internal weight and count totals.
A long press of the <PRINT> key will print and clear these totals. The six digit sequential number is not cleared.
Following is a sample of a total ticket:

000049 06/05/2003 15:20

90.6 lb G
000050 06/05/2003 15:21

154.9 lb G
000051 06/05/2003 15:21

50.4 lb G
000052 06/05/2003 15:21

71.0 lb G
000053 06/05/2003 15:21

13.3 lb G
ITEMS: 5
TOTAL: 380.2 lb

If counting is active each of the individual printouts would have a third line as discussed above and the
TOTAL would have an additional QTY line as follows:

000054 06/05/2003 15:22

13.3 lb G
27 p
000055 06/05/2003 15:23

79.3 lb G
159 p
000056 06/05/2003 15:23

117.0 lb G
234 p
ITEMS: 3
TOTAL: 209.6 lb
QTY: 420 p

9.2 Master Serial Output

In Master mode, the instrument sends out the entire contents of the LCD every 100msec. This is essentially the
same as AUTO output but the format of the output string is designed to allow a remote display to exactly copy the
contents of the LCD including all of the annunciators and user prompts, etc.

CF 147 26 version 1.1

10.0 SETPOINTS

The instrument is capable of wo rking with two internal setpoints. The status of these setpoints is displayed on the
LCD. Each setpoint is associated with a physical output driver but it may also be simply used as an indicator.

Refer to SET.PTS (Setpoint Settings ) section 7.4.6 for details on settings.

10.1 Setpoint Connection

Refer to Auxiliary Connection section 3.9 for the method of connection of the external output drivers.

10.2 Setpoint Operation

Setpoint 1 is configured as an overload setpoint. The SET.PTS:TARG.HI value sets the value for the overload limit.
Setpoint 2 is an underload setpoint and its limit value is set by SET.PTS:TARG.LO value.
The SET.PTS:SRC setting allows the gross weight or displayed weight to be chosen as the source for the setpoint
operation. This allows the overload and underload limits to be linked to gross weights always or alternatively to be
linked to the current displayed weights.

When the selected weight is greater than the TARG.HI value the over annunciator is visible and output 1
is activated.
When the selected weight is less than the TARG.LO value the under annunciator is visible and output 2
is activated.

11.0 SPECIAL FUNCTIONS

11.1 Introduction

The instrument has a special function key on the front panel. This function of this key can be configured to any of
the key functions detailed below. Refer to KEY.FN (Key Functions) section 7.4.4 to configure the function key.
When leaving the factory, the <FUNCTION> key is blank and has no primary function pre-programmed. Each
primary function has an associated overlay sticker (supplied) that should be applied to the function key to label the
function. Ensure the keypad is clean and dry before affixing the sticker. Refer to Cleaning section 3.4 for more
information.

11.2 Key Functions

2.8 kg G
000010 06/05/2003 16:31

6.1 lb G

11.2.5 HOLD and PEAK HOLD

The <HOLD> key implements a manual Hold function. The <PEAK> key implements a Peak Hold function where
the largest absolute weight, either positive or negative is stored in the peak value (e.g. -30 is larger than 25). The
Hold annunciator is active when the display is showing the held weight. Refer to Status Annunciators section 5.1.1.

To perform the Hold function, do the following:

• Press the manual <HOLD> key once to hold the current displayed weight.

• Press the manual <HOLD> key again to return the display to normal weighing.
To perform the Peak Hold function, do the following:

• Press the <PEAK> hold key once to show the absolute peak weight reading.

• Press the <PEAK> hold key again to return the display to normal weighing.

• A long press of the <PEAK> hold key clears the peak value back to 0 (zero).

All printouts that print the displayed weight will use the held weight reading if it is currently being displayed.

11.2.6 LIVE.WT

The <LIVE.WT> key is used to enable live weight averaging. With this feature, it is possible to determine the weight
of a continually moving mass (e.g. livestock).

• Press and hold the <LIVE WT> key to switch between normal weighing and live weight mode. The display will
briefly show NORMAL or LIVE.WT.

During normal weighing, this key operates exactly like a manual <HOLD> key.
In Live -Weight mode the following sequence is followed:

• While the net weight is within the zero 'dead' band, the instrument shows the current weight.

• Press the <TARE> or <ZERO> key to clear any residual weight and return the scale to the zero state.

• Place the mass to be weighed on the scale.

• Once the weight moves outside the zero 'dead' band the instrument begins to calculate a long term average that
compensates for any movement in the mass. The instrument flashes the Hold annunciator and shows the current
average value.

• The Hold annunciator is steady when the final sample weight is shown on the display.

• Press the <LIVE WT> key to force the sample to be re-calculated.

• Once the weight is returned to the zero 'dead' band, the cycle can be repeated.

11.2.7 SHOW.T

The SHOW.T item stands for Show Total. The function key will be labeled <TOTAL>.
The PRINT key is used not only to print the current weight but also to add that weight to the current total.

• When the <TOTAL> key is pressed the indicator displays count followed by the number of items in the total.

• After this, TOTAL is displayed followed by the current total weight.
If the total weight is too large to display in six digits, the weight is shown in two sections labeled with the upper six

digits displayed before the lower six digits.
A long press of the <PRINT> key causes the total accumulated weight to be printed and then cleared. The
SERIAL:TYPE option must be set to PRINT to activate this function.
