configure the digital inputs.
Digital outputs are typically used to
drive other equipment. Outputs are designed to sink,
rather than source, switching current. Each output is a
normally open collector circuit, capable of sinking 250
mA when active. Digital outputs are wired to switch
relays when the digital output is active (low, 0 VDC)
with reference to a 5 VDC supply.
Use the SETPTS menu to configure digital outputs.

3.0Configuration
To configure the 520 indicator, the indicator must be
placed in setup mode. The setup switch is accessed by
removing the large fillister head screw on the enclosure
backplate. Switch position is changed by inserting a
screwdriver into the access hole and pressing the
switch.
When the indicator is placed in setup mode, the word
CONFIG is shown on the display. The CONFIG menu is
the first of ten top-level menus used for configuring the
indicator. Detailed descriptions of these menus are
given in Section 3.2. When configuration is complete,
return to the CONFIG menu and press the
key to exit setup mode, then replace the
access screw.

3.1Configuration Methods
The 520 indicator can be configured by using the front
panel keys to navigate through a series of configuration
menus or by sending commands or configuration data
to the EDP port. Configuration using the menus is
described in Section 3.1.3.
Configuration using the EDP port can be accomplished
ing either the EDP command set described in
us
Section 9.0 or Version 3.0 or later of
configuration utility.
the Revolution
3.1.1Revolution Configuration
The Revolution configuration utility provides the
preferred method for configuring the
Revolution runs on a personal computer to set
configuration parameters for the indicator (see
Section 5.0 on page 44). When Revolution
configuration is complete, configuration data is
downloaded to
page 45). Figure 3-1 shows an example of one of the
Revolution configuration displays.
The EDP command set can be used to configure the 520
indicator using either a personal computer or terminal.
Like Revolution, EDP command configuration sends
commands to the indicator EDP port; unlike
Revolution, EDP commands can be sent using any
external device capable of sending ASCII characters
over a serial connection.
EDP commands duplicate the fu
the indicator front panel and provide some functions
not otherwise available. EDP commands can be used to
simulate pressing front panel keys, to configure the
indicator, or to dump lists of parameter settings. See
Section 9.0 on page 50 for more information about
using the EDP command set.

3.2Menu Structures and Parameter Descriptions
The following sections provide graphic representations of the 520 menu structures. In the actual menu structure, the
settings you choose under each parameter are arranged horizontally. To save page space, menu choices are shown
in vertical columns. The factory default setting appears at the top of each column and is bolded. Parameters shown
surrounded by a dotted-line box only appear under the special circumstances explained under each box.
Most menu diagrams are accompanied by one or more tables tha
t describe all parameters and parameter values
associated with that menu option. Default parameter values are shown in bold type.
The value entered must be in the range 1–9 999 999 and should be consistent with legal
requirements and environmental limits on system resolution.
To calculate GRADS, use the formula, GRADS = Capacity / Display Divisions.
Display divisions for primary and secondary units are specified on the FORMAT menu.
Automatically zeroes the scale when within the range specified, as long as the input is
within the ZRANGE and scale is at standstill. Selections are ± display divisions. Maximum
legal value varies depending on local regulations.
Selects the range within which the scale can be zeroed. The 1.9% selection is ± 1.9%
around the calibrated zero point, for a total range of 3.8%. Indicator must be at standstill to
zero the scale. Use 1.9% for Legal-for-Trade applications.
Sets the level, in display divisions, at which scale motion is detected. If motion is not
detected for 1 second or more, the standstill symbol lights. Some operations, including
print, tare, and zero, require the scale to be at standstill. Maximum legal value varies
depending on local regulations.
If this parameter is set to OFF, the standstill annunciator does not light; operations normally
requiring standstill (zero, tare, print) are performed regardless of scale motion. If OFF is
selected, ZTRKBND must also be set to OFF.
Determines the point at which the display blanks and an out-of-range error message is
displayed. Maximum legal value varies depending on local regulations.
Sample rate. Selects measurement rate, in samples per second, of the analog-to-digital
converter. Lower sample rate values provide greater signal noise immunity. If instability
occurs, use lower sample rate to reduce signal noise.
Selects the digital filtering rate used to reduce the effects of mechanical vibration from the
immediate area of the scale.
Choices indicate the number of A/D conversions per update that are averaged to obtain the
displayed reading. A higher number gives a more accurate display by minimizing the effect
of a few noisy readings, but slows down the settling rate of the indicator.
Enables RATTLETRAP® digital filtering. RATTLETRAP is most effective at filtering repeating
vibrations caused by mechanical noise from nearby machines but may increase settling
times over standard digital filter selections.
Digital filter cutout sensitivity. Specifies the number of consecutive readings that must fall
outside the filter threshold (DFTHRH parameter) before digital filtering is suspended.

Regulatory mode. Specifies the regulatory agency having jurisdiction over the scale site.
• OIML, NTEP, and CANADA modes allow a tare to be acquired at any weight greater than
zero. NONE allows tares to be acquired at any weight value.
• OIML, NTEP, and CANADA modes allow a tare to be cleared only if the gross weight is at
no load. NONE allows tares to be cleared at any weight value.
• NTEP and OIML modes allow a new tare to be acquired even if a tare is already present.
In CANADA mode, the previous tare must be cleared before a new tare can be acquired.
• NONE, NTEP and CANADA modes allow the scale to be zeroed in either gross or net
mode as long as the current weight is within the specified ZRANGE. In OIML mode, the
scale must be in gross mode before it can be zeroed; pressing the ZERO key in net mode
clears the tare.

The following topics provide additional information about
compensating for environmental factors (Section 4.4.1)
and diagnostic information for determining expected zero
nd span coefficients.
a
4.4.1Adjusting Final Calibration
Calibration may be affected by environmental factors
including wind, vibration, and angular loading. For
example, if the scale is calibrated with 1000 lb, a strain
test may determine that at 2000 lb the calibration is 3 lb
high. In this case, final calibration can be adjusted by
tweaking WVAL to 998.5 lb. This adjustment provides
a linear correction of 1.5 lb per 1000 lb.
To adjust the final calibration, return to the
prompt and press to show the test weight value.
Press
or to adjust calibration up or down. Press

4.4.2Gravity Compensation
This feature is used to compensate for the variance in
gravitational pull from one location to another and is
available for the
compensation, the GRAVADJ parameter under the
PROGRM menu must be set to ON (see Section 3.2.5 on
page 30), and the LATITUD (latitude) and ELEVATN
(elevation in meters, relative to sea level) parameters
set before calibrating
page 40).
If the indicator is later installed at a different location,
vity compensation can be applied to a pre-calibrated
gra
indicator by adjusting the LATITUD and ELEVATN
parameters.

COUNTING MODE KEY FUNCTIONS
The 520 provides a piece count mode that allows the
indicator to serve as a counting scale. In piece count
mode, the indicator display shows the number of parts
on the scale rather than the weight of those parts.
Legal-for-Trade applications require product to
be sold by weight rather than an equivalent
pa
rts count. Operator access to piece count
mode is disabled when the indicator is shipped
from the factory.
To enable operator access to piece count mode, set the
ACCESS parameter to ENABLE (COUNT submenu
on the PROGRM menu) or send the CNTMOD=
ENABLE EDP command.
Piece count mode has two submodes:
•Count display mode displays the current parts
count and allows
ticket printing using the
CFMT print format.
•Sample acquisition mode is used t
o calculate
the average piece weight of the sample for
parts counting.
Count Display Mode
Piece count mode is entered by pressing the MODE
(GROSS/NET) key from normal weighing mode. In
count display mode, the display shows the number of
parts rather than weight, the two-digit annunciator
displays
PC, and pressing the PRINT key sends the
CFMT print format data string to the serial port.
If a sample weight has not yet been acquired, the
or switches automatically to sample acquisition
indicat
mode.
Sample Acquisition Mode
Sample acquisition mode is used to select the sample
quantity and calculate the average piece weight for the
parts being counted.
To set a new sample weight, do the following:
1. Place empty parts container on scale. Wait for
standstill, then
press TARE to acquire the tare
weight of the container.
2. Press
3. From count display mode, press the

placed on the scale. Add the number of parts
shown or choose a different sample size by
pressing the
SAMPLE key to scroll through the
selectable sample quantities (5, 10, 20, 50,
100).
5. Once the sample quantity is on the scale, press
ENTER to calibrate the indicator for counting
the new parts. The indicator display shows the
message
–CNT– as it acquires the sample
weight, then switches to count display mode
and shows the part quantity.
If the weight of the sample quantity is

The 520 provides a checkweigh mode that can be
enabled for either absolute values (ABS) or percent
values (PERCENT).
Checkweighing Modes
•ABSOLUTE allows you to enter actual weight
values for over and under (values can be either
positive or negative).
•PERCENT allows you to enter a target weight
and percentages of this value (in whole

percent values) for over and under.
Autoprint Modes
•WAITSS print mode performs an automatic
print any time the weight settles out of motion
within the ACCEPT range. The autoprint is
reset each time the scale goes into motion and
then achieves standstill within the acceptable
weight range.
•TARGET print mode performs automatic print
any time the weight settles out of motion
within the ACCEPT range. To reset, the scale
weight must return to within the zero band, as
specified in the CKZBAND parameter, and
then achieve standstill again within the
acceptable weight range.

9.0EDP Commands
The 520 indicator can be controlled by a personal
computer or terminal connected to the indicator EDP
port. Control is provided by a set of EDP commands
that can simulate front panel key press functions,
display and change setup parameters, and perform
reporting functions. The EDP port provides the
capability to print configuration data or to save that
data to an attached personal computer. This section
describes the EDP command set and procedures for
saving and transferring data using the EDP port.
9.1The EDP Command Set
The EDP command set can be divided into five groups:
key press commands, reporting commands, the
RESETCONFIGURATION special function
command, parameter setting commands, and transmit
weight data commands.
When the indicator processes an EDP command, it
sponds with the message

executed. If the command is unrecognized or cannot be
executed, the indicator responds with
The following sections list the commands and

9.1.1Key Press Commands
Key press EDP commands (see Table 9-1) simulate
pressing the keys on the front panel of the indicator.
These commands can be used in both setup and
ing mode. Several of the commands serve as
weigh
“pseudo” keys, providing functions that are not
represented by a key on the front panel.

9.1.7Batching Control Commands
The commands listed below provide batching control through the EDP port.
BATSTART
If the BATRUN digital input is active (low) or not assigned, the BATSTART command can be used to start the
batch program.
BATRESET
Stops the program and resets the batch program to the first batch step. Run the BATRESET command after
making changes to the batch configuration.
BATPAUSE
Stops the batch program at the current step. All digital outputs set on by the current step are set off. The
BATSTRT DIGIN or BATSTART EDP commands can be used to restart the batch program at the current step.
BATSTATUS
The BATSTATUS command is used to check the current status of various setpoint and batching conditions.
BATSTATUS returns 14 bytes of status data as described in Tabl e 9-15. BATSTATUS is principally used to
provide status information to a controlling batch program when
using the Remote I/O Interface option.
Status information returned in bytes 3–
12 is coded as ASCII characters @ (hex 40) through O (hex 4F); only
the low order bits of these characters are significant. Table 9-15 shows the low order bit assignments for bytes
3–12. Use Tab le 9-16 on page 60 to interpret the status of the low order bits for a given ASCII

10.0Print Formatting
The 520 provides seven print formats. Formats GFMT, NFMT, EDPFMT, and CFMT will be printed in a ticket
format based on the current mode of operation when the
HDRFMT can be inserted into any other ticket format using the <AE> formatting command. SPFMT is printed if
PSHPRINT is set to ON or WAITSS in the setpoint configuration. STRMFMT defines what the streamed output
will be if the FORMAT parameter is set to CUSTOM.
Each print format can be customized to include up to 300 characters of information, such as company name and
address, on print tickets. You can use the indicator front panel (PFORMT menu), EDP commands, or the
Revolution® configuration utility to customize the print formats.
10.1Print Formatting Commands
Table 10-1 lists commands you can use to format the 520 print formats. Commands included in the format strings
must be enclosed between < and > delimiters. Any characters outside of the delimiters are printed as text on the
ticket. Text characters can include any ASCII character that can be printed by the output device.

10.3Customizing Print Formats
The following sections describe procedures for customizing print formats using the EDP port, the front panel
(PFORMT menu), and the Revolution® configuration utility. See Section 12.7 on page 77 for information about
custom stream formatting.
With a personal computer, terminal, or remote keyboard attached to the 520 EDP port, you can use the EDP
command set to customize the print format strings.
To view the current setting of a format string type the name of the
check the current configuration of the GFMT format, type GFMT and press
print format and press ENTER. For example, to
ENTER. The indicator responds by
sending the current configuration for the gross format:
GFMT=<G> GROSS<NL>
To change the format, use the GFMT or NFMT EDP command followed by an equals sign (=) and the modified
print format string. For example, to add the name and address of a company to the gross format, you could send the
following EDP command:
GFMT=JOE'S SALVAGE<NL>1167 EAST HIGHWAY ROAD<NL>ANYTOWN<NL2><G> GROSS<NL>
A ticket printed using this format might look like the following:
JOE'S SALVAGE
1167 EAST HIGHWAY ROAD
ANYTOWN
1345 LB GROSS
The ticket above could also be formatted by specifying the company address information in the HDRFMT ticket
format, then substituting the <AE> command for the address in the GFMT ticket format:
HDRFMT=JOE'S SALVAGE<NL>1167 EAST HIGHWAY ROAD<NL>ANYTOWN<NL2>GFMT=<AE><G> GROSS<NL>
10.3.2 Using the Front Panel
If you have no access to equipment for communication through the EDP port or are working at a site where such
equipment cannot be used, you can use the PFORMT menu (see Figure 10-1) to customize the print formats. Using
the PFORMT menu, you can edit the print format strings by
in the format string.
changing the decimal values of the ASCII characters
Lower-case letters and some special characters cannot be displayed on the 520 front panel (see the ASCII

11.0Setpoints
Note
The 520 indicator provides eight configurable setpoints for control of both indicator and external equipment
functions. Setpoints are configured to trip based on specified conditions; tripping the setpoint can be used to
request indicator functions (print, tare, accumulate) or to change the state of a digital output controlling external
equipment.
11.1Batch and Continuous Setpoints
520 setpoints can be either continuous or batch setpoints.
Continuous setpoints are free-running: the indicator constantly checks the input channel for the setpoint value
at each A/D update. If the input channel weight reading matches the setpoint value, the indicator sets the
corresponding digital output on.
Batch setpoints are active one at a time, in an ordered sequence. The 520 can use batch setpoints to control up
to eight separate batch processing steps. A digital output associated with a batch setpoint is on until the setpoint
condition is met, then latched for the remainder of the batch sequence.
To use batch setpoints, you must activate the BA
whether a batch sequence is automatic or manual. AUTO sequences repeat continuously, while MANUAL
sequences require a BATSTRT digital input or BATSTART EDP command before restarting. As shown in
Table 11-1 on page 65, GROSSSP, NETSP, and RELSP setpoint kinds can
continuous setpoints.
If the checkweigh function is enabled, setpoints remain configured but do not function until checkweigh is
disabled.
The BATCH parameter must also be set on for each batch setpoint. If the setpoint is defined but the BATCH
parameter is off, the setpoint operates as a continuous setpoint, even during batch sequences.

DELAYDelays the batch sequence for a specified time. The length of the delay (in
tenths of a second) is specified on the Value parameter.
WAITSSWait for standstill. Holds the batch sequence until the scale is at standstill.
COUNTERSpecifies the number of consecutive batch sequences to perform. A
BATRESET needs to be sent (through either a serial command or digital input)
or a new counter value entered for COUNTER setpoint to function properly.

TIMERTracks the progress of a batch sequence based on a timer.
The timer value, specified in tenths of a second on the VALUE parameter,
determines the length of time allowed between start and end setpoints. The
indicator START and END parameters are used to specify the start and end
setpoints. If the END setpoint is not reached before the timer expires, the digital
output associated with this setpoint is activated.
CONCURAllows a digital output to remain active over a specified portion of the batch
sequence. Two types of concur setpoints can be configured:
Type 1 (VA L U E = 0 ) : The digital output associated with this setpoint becomes
active when the START setpoint becomes the current batch step and remains
active until the END setpoint becomes the current batch step.
Type 2 (VALUE > 0): If a non-zero value is specified for the VALUE parameter, that
value represents the timer, in tenths of a second, for this setpoint. The digital
output associated with this setpoint becomes active when the START setpoint
becomes the current batch step and remains active until the timer expires.
NOTE: If more than one concurrent setpoint is configured, each must be
assigned to a different digital output.
Figure 11-1 shows the general structure of the SETPTS menu. See Section 3.2.7 on page 35 for a detailed
description of the SETPTS menu. The eighteen setpoint kinds
are described in Table 11-1 on page 65.

GROSSSP, NETSP, and RELSP setpoint types: Allows the digital output associated
with a setpoint to shut off before the setpoint is satisfied to allow for material in
suspension.
The ON value adjusts the setpoint trip value up or down (depending on the TRIP
parameter setting) from the setpoint value.
The LEARN value can be used to automatically adjust the preact value after each
batch. LEARN compares the actual weight at standstill to the target setpoint value,
then adjusts the preact by half of the difference after each batch.
The FLOW value provides compensation for material flow rate in determining when to
shut off the digital output. Rather than waiting for the specified weight to be reached,
FLOW preact uses the change in weight over time to anticipate when the preact
weight value will be reached.
setpoints with PREACT set to ON or LEARN. Depending on the TRIP setting
specified for the setpoint, the setpoint trip value is adjusted up or down by the preact
value.
GROSSSP, NETSP, and RELSP setpoint types: Specifies the preact variable for
setpoints with PREACT set to LEARN or FLOW.
PREADJ variable sets what percentage of error correction applied each time a preact
adjustment is made (default is 50%)
PRESTAB variable is timeout for PREACT LEARN value. For setpoints set to LEARN
or FLOW, PRESTAB specifies the time (in 0.1 second intervals) to wait for standstill
before adjusting the preact value. PREACT is not recalculated if standstill is not
achieved (default is 0).
PREBAND defines a band value that will prevent the PREACT from becoming
skewed if a large amount of product falls into the scale at the end of a filling cycle
(default is 0.0).
PRE CNT is PREACT LEARN interval. For setpoints set to LEARN or FLOW, PRE
CNT specifies the number of batches after which PREACT is recalculated. Default
value of 1 specifies that PREACT will be recalculated after every batch cycle.
this setpoint is:
• For +RELSP, the value of the relative setpoint plus the value (VALUE parameter) of
this setpoint
• For –RELSP, the value of the relative setpoint minus the value of this setpoint
• For %RELSP, the percentage (specified on the VALUE parameter for this setpoint)
of the relative setpoint
GROSSSP, NETSP, and RELSP setpoint types: Specifies whether the setpoint is
used as a batch (ON) or continuous (OFF) setpoint.
GROSSSP, NETSP, RELSP, PAUSE, DELAY, and WAITSS setpoint types: Specify ON
to update the accumulator and perform a print operation when the setpoint is
satisfied. Specify ONQUIET to update the accumulator without printing.
GROSSSP, NETSP, RELSP, PAUSE, DELAY, and WAITSS setpoint types: Specify ON
to perform a print operation when the setpoint is satisfied; specify WAITSS to wait for
standstill after setpoint is satisfied before printing.
GROSSSP, NETSP, RELSP, PAUSE, DELAY, and WAITSS setpoint types: Specify ON
to perform an acquire tare operation when the setpoint is satisfied. NOTE: PSHTARE

12.6.1 Continuous Output Serial Data Format
If continuous transmission is configured for the EDP or
printer port (STREAM parameter on the SERIAL
menu), the
520 sends data using the Consolidated
Controls serial data format shown in Figure 12-1:
Figure 12-1. Continuous Output Serial Data Format
12.6.2 Demand Output Serial Data Format
When demand mode is configured for the EDP or
printer port in the setup menus (PRNDEST on the
SERIAL menu), the
520 uses a data string formatted for
a basic ticket printout. The particular ticket format
printed depends on the indicator configuration.
You can use the EDP port or keypad to fully customize
ticket to work with a wide variety of printers,
the
scoreboard displays, and other remote equipment. See
Section 12.0 on page 73 for more information on
custom print formats.
12.6.3 RS-485 Data Formats
The 520 has a built-in RS-485 software protocol which
is enabled when you assign a non-zero address to the
indicator. Valid RS-485 addresses must be in the range
1–255; the address is specified on the ADDRESS
parameter on the SERIAL menu.
All remote commands are initiated using the data
format shown in Figure 12-2:
If the initiating device address matches the port address
520 on the RS-485 network, that indicator
of a
responds. For example, with demand outputs, or in
response to a XG command, the responding indicator
uses the format shown in Figure 12-3:
Figure 12-3. RS-485 Respond Data Format
Example: To send the XG command from an ASCII
terminal to an indicator at address 65 (decimal) on the
RS-485 network, use the format shown in Figure 12-2.

12.7Custom Stream Formatting
Each port can be independently configured to stream a default frame format or can be customized to stream a
user-defined format. Custom formatting is very similar to the standard print formatting described in

Standard digital filtering uses mathematical averaging
to eliminate the variant digital readings that the A/D
converter sends periodically because of external
vibration. Digital filtering does not affect the indicator
measurement rate, but does affect the settling time. The
selections from 1 to 256 reflect the number of readings
averaged per update period. When a reading is
encountered that is outside a predetermined band, the
averaging is overridden, and the display jumps directly
to the new value.
12.10.1DIGFLTx Parameters
The first two digital filtering parameters, DIGFLT1,
and DIGFLT2, are configurable filter stages that
control the effect of a single A/D reading on the
displayed weight. The value assigned to each
parameter sets the number of readings received from
the preceding filter stage before averaging.
A rolling average from filter one is placed in filter two.
The overall filtering is effectively a weighted average
of the product of the values (DIGFLT1 X DIGFLT2)
within a time frame equivalent to the sum of the values
(DIGFLT1 + DIGFLT2).
Setting the filters to 1 effectively disables digital
filtering.
12.10.2RATTLETRAP® Filtering
RATTLETRAP digital filtering (RATTRAP parameter
set ON) uses a vibration-dampening algorithm to
provide a combination of the best features of analog
and digital filtering. The RATTLETRAP algorithm
evaluates the frequency of a repeating vibration then
derives a composite displayed weight equal to the
actual weight on the scale less the vibration-induced
flaws. It is particularly effective for eliminating
vibration effects or mechanical interference from
nearby machinery. Using RATTLETRAP filtering can
eliminate much more mechanical vibration than
standard digital filtering, but will usually increase
settling time over standard digital filtering.
12.10.3DFSENS and DFTHRH Parameters
The digital filter can be used by itself to eliminate
vibration effects, but heavy filtering also increases
settling time. The DFSENS (digital filter sensitivity)
and DFTHRH (digital filter threshold) parameters can
be used to temporarily override filter averaging and
improve settling time:
•DFSENS specifies the number of consecutive
scale readings that must fall outside the filter
threshold (DFTHRH) before digital filtering is
suspended.
•DFTHRH sets a threshold value, in display
divisions. When a specified number of
consecutive scale readings (DFSENS) fall
outside of this threshold, digital filtering is
suspended. Set DFTHRH to NONE to turn off
the filter override.
12.10.4Setting the Digital Filter Parameters
Fine-tuning the digital filter parameters greatly
improves indicator performance in heavy-vibration
environments. Use the following procedure to
determine vibration effects on the scale and optimize
the digital filtering configuration.
1. In setup mode, set the digital filter parameters
(DIGFLT1 and DIGFLT2) to 1. Set DFTHRH
to NONE. Return indicator to normal mode.
2. Remove all weight from the scale, then watch
the indicator display to determine the
magnitude of vibration effects on the scale.
Record the weight below which all but a few
readings fall. This value is used to calculate the
DFTHRH parameter value in Step 4.
For example, if a heavy-capacity scale
produces vibration-related readings of up to 50
lb, with occasional spikes to 75 lb, record 50 lb
as the threshold weight value.
3. Place the indicator in setup mode and set the
DIGFLTx parameters to eliminate the vibration
effects on the scale. (Leave DFTHRH set to
NONE.) Find the lowest effective value for the
DIGFLTx parameters.
4. Calculate the DFTHRH parameter value by
converting the weight value recorded in Step 2
to display divisions:
threshold_weight_value / DSPDIV
In the example in Step 2, with a threshold
weight value of 50 lb and a display division
value of 5D:
set to 10DD for this example.
5. Finally, set the DFSENS parameter high
enough to ignore transient peaks. Longer
transients (typically caused by lower vibration
frequencies) will cause more consecutive
out-of-band readings, so DFSENS should be
set higher to counter low frequency transients.
Reconfigure as necessary to find the lowest
effective value for the DFSENS parameter.
50 / 5D = 10. DFTHRH should be

12.11 Conversion Factors for Secondary Units
Note
The 520 has the capability to mathematically convert a
weight into many different types of units and instantly
display those results with a press of the
Secondary units can be specified on the FORMAT
u using the SECNDR parameter, or by using EDP
men
commands.
•To configure secondary units using the front
nel menus, use the Table 12-11 to find the
pa
conversion multiplier for the MULT parameter.
For example, if the primary unit
the secondary unit is short tons, set the MULT
parameter to 0.000500.
•To configure secondary units using EDP
commands, use
the Table 12-11 to find the
conversion multiplier for the SEC.MULT
command. For example
, if the primary unit is
pounds and the secondary unit is short tons,
send the EDP command SEC.MULT=
0.0005<CR> to set the multiplier for the
secondary units.
Ensure that the secondary decimal point
position is set appropriately for the scale
capac
ity in the secondary units. If the converted
value requires more digits than are available,
the indicator will display an overflow message
(OVERFL).
For example, if the primary units are short tons,
secondary units are pounds, and the secondary decimal
point is set to 8888.888, the indicator will overflow if 5
tons or more are applied to the scale. With 5 tons
applied, and a conversion factor of 2,000, the
secondary units display needs five digits to the left of
the decimal point to display the 10,000 lb secondary
units value.
The following calibration procedure requires a multi
meter to measure voltage or current output from the
analog output module. If the option is not already
installed, see Section 2.4 on page 8.

The analog output must be calibrated after the
indicator itself has been configured
