weigh mode. In the event of a power failure while in the setup mode, any changes that
have been made will be lost.
13
Select Scale Capacity
When the setup mode is accessed, the first parameter displayed is the capacity
parameter. The capacity parameter toggles the display between CAPAj and the current
capacity. The capacity can be expressed in lb or kg. The UNITS annunciator to the right
of the weight display will indicate either lb or kg. The calibration and capacity setup unit is
defined by the startup units Units parameter setting.

5000 divisions. To enter a different resolution, press the UNITS button until the display
momentarily shows Cnt by and then displays the current resolution.
The resolution can be a value between 200 and 50,000 divisions of capacity. The UNITS
annunciator to the right of the weight display will indicate either lb or kg. Press the ZERO
button to increment through the available range of possible resolutions. Once maximum
resolution has been reached, the level will roll over to the minimum value.
Zero and Span Calibration
Press the UNITS button until CAL 0appears on the display. Remove all weight from the
scale platter. To ensure fast and accurate calibration, be sure there are no air currents or
vibration present.
Press ZERO and wait for the display to count down to 0. If the calibration zero is
accepted, the display will read CAL FS. If the display reads CAL 0, repeat the zero point
calibration process.
NOTE: If Ernno appears during the calibration count down, the scale is in motion. All
vibrations and air currents must be removed from the scale platform to complete the
calibration process.
NOTE: If rg Err appears on the display, the calibration zero is out of range. Press ZERO
to clear the error. Refer to the A/D Ranging section for additional information.
To perform the span calibration, place the calibration weight on the platform. Use the
numeric keypad to enter the desired calibration weight and press ENTER. The span
point can be calibrated using any weight between 2% and 100% of scale capacity. Wait
for the display to count down to 0. If the span calibration is successful, the display will
return with donE.
If the display returns to CAL 0, the A/D is auto ranging, and you will need to repeat the
zero and span calibration process.
14
NOTE:
If Er dP appears on the display, the calibration span weight value has an incorrect
decimal point location.
If Er cnt appears on the display, the calibration span weight value has a count by
resolution greater than that of the indicator's count by resolution.
If Er nEg appears on the display, the calibration span is in a negative range. Check
polarity of load cell connection and repeat zero and span calibration.
If SPAn Eappears on the display, the calibration span is out of range. Press ZERO to
clear this error. Refer to the A/D Ranging section for additional information.
WARNING: Calibration at 2% of capacity has been provided as a convenience to
customers with high capacity scales in remote or inaccessible locations. Scales
calibrated at 2% of capacity may have more errors at full capacity than scales calibrated
at 25% or 50%. Hardy Process Solutions recommends that all scales be calibrated at full
capacity whenever possible.

A/D Range Troubleshooting
On scales with factory installed platforms, the zero and span will lie within permissible
limits. The allowable load cell signal input range is from 0.112 mV/V to 7 mV/V.
1) Enter the calibration mode.
2) Press PRINT until the A/D raw counts are displayed.
3) Remove all items from the platform and record the dead load raw counts
reading.
4) The dead load raw counts must be between -50,000 and 1,900,000 counts. If
the readings are outside of the limits specified, change the dead load until you
meet these requirements.
5) Place full capacity on the platform and record the raw counts. Subtract the dead
load counts from the full load counts to calculate the span. Refer to Table 1 and
verify that the span falls within the specified range. The "Full Load" raw counts
(span + dead load) should not exceed 1,999,999 counts.
6) When using 75%, 50%, 25%, 20% or 10% of full load to calibrate, refer to Table
1 for full load, 75%, 50%, 25%, 20%, 10% span ranges.
Platform load Minimum span
Full 30,000
75% 22,500
50% 15,000
25% 7,500
20% 6,000
10% 3,000

Parameter Setup Mode
The indicator provides many parameters that allow you to customize the operation of
your indicator to meet your application’s needs. To access these parameters the setup
mode must be accessed, which can be entered using any of the three methods below.
Power–up Front Panel Setup Mode Access
To enter the calibration mode, power up the indicator while pressing and holding the
ZERO and the UNITS buttons. When rEL Pb is displayed, release both buttons. The
display will momentarily read Ent Cd, and then go blank. Press the ZERO button five
times. The display will indicate the number of times the ZERO button has been pressed.
When 5is displayed, press the UNITS button and wait a few seconds.
Note: If the code is not entered before the timer is finished, the scale will bypass code
entry and enter the normal run mode. The front panel access feature during power-up is
not available when the Operating Mode (oP)parameter is set to 44S.
Front Panel Setup Mode Access
To enter the calibration mode, press and hold the UNITS and ZERO buttons until the
parameter review starts (Cand Pare displayed). Press the HIDDEN button, located to
the right of the display after Capaj and the capacity is displayed. The display will
momentarily read Ent Cd, and then go blank. Press the ZERO button five times. The
display will indicate the number of times the ZERO button has been pressed. When 5is
displayed, press the UNITS button and wait a few seconds.
NOTE: If the code is not entered before the timer is finished, the scale will bypass code
entry and enter the normal run mode. The front panel access feature during power-up is
not available when the Operating Mode (oP)parameter is set to 44S.
Switch Setup Mode Access
The calibration switch can be accessed by removing the meter’s back cover. With the
indicator powered on, press the CAL switch (S1), located in the lower left corner of the
main board. Pressing the CAL switch also exits the setup mode and saves any changes.
Warning: do not press the CAL switch while powering up the scale, this will cause the
scale to reset all parameter settings.
Exiting the Setup Mode
To exit the Calibration and Parameter Setup Menu, momentarily press the CAL switch or
scroll through the menu options, by pressing the UNITS button, until donE nappears.
Press the ZERO button until donE yappears and then press the UNITS button. The
indicator will return to the normal weighing mode. If any menu selections were changed,
the new values will be saved.
Note: No new setup information is saved until the scale displays SAVEd and returns to
the weigh mode. In the event of a power failure while in the setup mode, any changes
that have been made will be lost.
