3.0 Configuration

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.

3.1 Configuration 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

3.1.1 Revolution 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.

Figure 3-1. Sample Revolution Configuration Display

3.1.2 EDP Command Configuration

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.

Specifies the number of full scale graduations.
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.

Specify prompts for use in setpoint names (up to 16 characters). Prompts are referenced by the NAME parameter under the SETPTS submenus; prompts appear in the secondary display area during setpoint execution for batch type setpoints.
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 value specified for this parameter affects the function of the front panel TARE and ZERO keys. See Section 12.5 on page 75 for a complete description of TARE and ZERO key functions for each of the regulatory modes.
Regulatory word for GROSS. Specifies GROSS or BRUTTO.

4.4 More About Calibration

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

4.4.1 Adjusting 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 to save the value, then press to return to the CALIBR menu.

4.4.2 Gravity 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

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
value 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.

9.0 EDP 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.

9.1 The 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

9.1.7 Batching 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

10.0 Print 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.

10.1 Print 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.

Note
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.

The Revolution configuration utility provides a print formatting grid with a tool bar. The grid allows you to construct the print format without the formatting commands (<NL> and <SP>) required by the front panel or EDP command methods. Using Revolution, you can type text directly into the grid, then select weight value fields from the tool bar and place them where you want them to appear on the printed ticket.

11.0 Setpoints

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.

11.1 Batch 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.

PAU SE Pauses the batch sequence indefinitely. Operator must activate the BATSTRT
digital input to continue processing.
DELAY Delays the batch sequence for a specified time. The length of the delay (in
tenths of a second) is specified on the Value parameter.
WAITSS Wait for standstill. Holds the batch sequence until the scale is at standstill.
COUNTER Specifies 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.
AUTOJOG Automatically jogs the previous filling operation.
COZ Center of zero. The digital output associated with this setpoint is activated
when the scale is at center of zero. No value is required for this setpoint.
INMOTON In motion. The digital output associated with this setpoint is activated when the
scale is not at standstill. No value is required for this setpoint.
INRANGE In range. The digital output associated with this setpoint is activated when the
scale is within capacity range. No value is required for this setpoint.

–GROSS Negative gross weight. The digital output associated with this setpoint is
activated when the gross weight reading is less than zero. No value is required for this setpoint.
–NET Negative net weight. The digital output associated with this setpoint is activated
when the net weight reading is less than zero. No value is required for this setpoint.
BATCHPR Batch processing signal. The digital output associated with this setpoint is
activated whenever a batch sequence is in progress. No value is required for this setpoint.
TIMER Tracks 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.
CONCUR Allows 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.

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 acquires the tare regardless of the value specified for the REGULAT parameter on the PROGRM menu.

Note
The batching switch option, PN 19369, comes as a complete unit in an FRP enclosure, with legend plate, locking stop switch (mushroom button), and a run/start/abort 3-way switch.
Figure 11-7. Batching Switch Wiring Diagram
Both switches are wired into the indicator's digital I/O terminal strip as shown in Figure 11-7. Each switch uses a separate digital input.
Once cables and switches have been connected to the indicator
, use the setup switch to place the indicator in setup mode. Use the DIGIN menu (see Section 3.2.8 on page 38) to configure digital input functions. The default values for DIGIN1 and DIGIN2 are BATSTRT and BA
TRUN, respectively.
When configuration is complete, exit setup mode. Initialize the batch

12.4 Status Messages

Two EDP commands, P and ZZ, can be used to provide status about the indicator.
The P EDP command returns currently shown in the indicator’s primary display area.
The ZZ EDP command returns whatever is currently shown in both the primary and
ondary displays. Depending on the type of
sec device used to receive data from the indicator, the standstill and center of zero symbols may be shown as spaces or as special characters. The ZZ command returns information in the following format:
PPPPPPP uu ssssssssssssssss
where:
PPPPPPP is the information shown on the
primary display
uu is the 2-digit units annunciator
ssssssssssssssss is the contents of the
secondary display
If the indicator is in an underrange or overload condition, the weight
value is replaced with

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,

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:

terminal to an indicator at address 65 (decimal) on the RS-485 network, use the format shown in Figure 12-2.

12.10 Digital Filtering

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.
Figure 12-4. Analog Output Menu
The analog output must be calibrated after the indicator itself has been configured (Section 3.0) and calibrated (Section 4.0).
1. Enter setup mode and go to the ALGOUT menu (see Figure 12-4):
Set OFFSET to 0% for 0–10 V output,
% for 4–20 mA output
20
Set mode select jumper on analog output
board to “V”
for 0-10 V output, or “I” for
4-20 mA output
Set MIN to lowest weight value to be
tracked by
the analog output
Set MAX to highest weight value to be
tracked by
the analog output
2. Connect multimeter to connector J1 on the
alog output board:
