CHAPTER 2: GETTING STARTED
After unpacking the scale, a small amount of preparation is required before the scale can be
used. All PALLET RUNNER 3000 models are factory tested and calibrated prior to delivery.
1. Remove all packaging from scale.
2. Position the scale on a firm, flat surface.
3. Lower the forks by squeezing the hand control upwards. The hand control is located
at the top of the swivel handle.
4. Turn the scale’s power ON to begin use. (If the display is not at a zero weight reading,
press the Zero key).
5. Slide the Pallet Runner forks under any standard pallet. (For optimum weighing
accuracy, the forks must be at least ¾ of their length under the pallet to be weighed).
6. Engage the lift mechanism by lowering the hand control. It may be necessary to hit
the release button before doing so.
7. Lift the pallet by cranking the handle in an UP/DOWN direction a minimum of 3
complete cycles. Now view the display for the weight value.
NOTE: Your PALLET RUNNER 3000 will automatically shut off after five minutes of non-
use. To change this setting, see Chapter 5.
For best results, be sure to follow these general guidelines:
•If using the AC adapter, do not share an AC outlet with electrical noise producing
equipment, such as refrigeration units. This includes products with electrical motors
and/or relays.
•Do not place the scale in an area with changing ambient temperature and/or high
humidity.
•Do not place the scale in an area with vibrating equipment.
•You may obtain a weight reading while moving, however for the best accuracy a
static weighment is advised.

3.2.1 FUNCTION KEYS
Units – This key toggles the scale among the available weight units. Available weight
units as shipped from the factory include lb, kg and pieces.
Zero/OFF – When held for three seconds, powers the scale OFF. Otherwise, this key
sets the scale to display zero provided the following conditions are met:
1. The scale is displaying Gross weight.
2. The scale is not in motion.
3. The scale is not in overload (see Appendix C for error codes).
Net/Gross - This key toggles the scale between Gross weight and Net weight only if a
Tare has been established.
Tare - This key is used to establish a Tare provided the following conditions are met:
1. The scale is not at or below Gross zero.
2. The scale is not in motion.
3. The scale is not in overload (see Appendix C for error codes).
ON/Print – This key is used to turn the scale ON. (The Print function is not available
on this model).
3.3 GENERAL SCALE OPERATION
3.3.1 WEIGHING AN ITEM
1. Select the desired weighing unit by pressing the UNITS key until that unit is
indicated on the display.
2. If necessary, press the ZERO key to obtain a weight reading of zero.
3. Raise the object to be weighed off the floor and allow the weight indication to
stabilize. If the item weight exceeds the scale’s weight capacity, it displays
“”.
4. Read the weight shown on the display.
3.3.2 TARING AN ITEM
To weigh an item in a container or on a pallet, the weight of that container or pallet
must first be subtracted from the overall weight to obtain an accurate weight reading.
This is known as taring.
1. Select the desired weighing unit by pressing the UNITS key until that unit is
indicated on the display.
2. If necessary, press the ZERO key to obtain a weight reading of zero.

8
3. Raise the empty container or pallet off the floor and allow the weight indication to
stabilize.
4. Press the TARE key. The display shows zero weight and turns the NET
annunciator on.
5. Place the material to be weighed on the container or pallet, raise it off the floor
and allow the weight indication to stabilize.
6. Read the weight shown on the display.
7. You may toggle between the gross weight and the net weight by pressing the
NET/GROSS key.

CHAPTER 4: ADVANCED FEATURES AND OPERATION
4.1 PIECE COUNTING
This mode is used to indicate the number of pieces of an item you have placed on the
scale’s forks and is accessed by pressing the UNITS key. To ensure accuracy, the
parts you are counting must be consistent in weight.
The scale uses the sampling method to determine the average piece weight (APW) of
the items you wish to count. When sampling items, always count the parts in your
hand and place them on the scale all at once. If the APW of the items is too light or
the total weight of the sample is too light, accuracy cannot be guaranteed. You will get
an error message, but piece counting will still be allowed.
1. Press the UNITS key until “PCS” is indicated on the display. If a previous sample
has not been taken, the scale will display “10 0”. If a previous sample has been
taken, the scale will display the current number of pieces on the platform.
2. If the items you will be counting require a container or pallet, you must first tare
the container or pallet off by pressing the TARE key.
3. If the screen does not show “10 0”, press the TARE key once. The scale is
prompting you to place ten identical items on the scale’s forks.
NOTE: If you wish to change the sample number, simply press the NET/GROSS
key repeatedly until the desired sample number appears. Available choices are 5,
10, 25, 50 and 100.
4. Place the sample items on the scale’s forks all at once and allow the weight
indication to stabilize. Once this is done, the zero indicated after the sample
number will change to a “–“. For example, “10 –“.
5. Press the NET/GROSS key to take the sample. If the sample size is large
enough, the scale now displays the number of pieces on the forks. If it does not,
the scale briefly displays “Add” and automatically increments the sample size.
Repeat Step #4 with the new sample size.
NOTE: If the scale continues to display “Add” even after sampling 100 pieces, the
unit weight of the items you wish to count is too light for your scale to process
accurately.
6. To exit the piece count mode, press the UNITS key. The APW will remain in
scale memory until you repeat Steps # 2 or #3.

CHAPTER 6: SCALE CALIBRATION
6.1 SCALE CALIBRATION OVERVIEW
The PALLET RUNNER 3000 scale may be calibrated with any precision test weight
between 30 pounds and 3000 pounds. The recommended test weight is 2000 pounds, but
in general the larger the test weight, the more accurate the scale will be.
Before you can calibrate the scale, you must enter the Setup Menu. See Section 5.2.1 for
instructions on how to do this.
6.2 ZERO CALIBRATION (F16)
1. While in the Setup mode, scroll to "F 16", then scroll down once using the ZERO/OFF
key to enter zero calibration menu. The display will momentarily show "C 0" followed by
a value. This value is the internal A/D count and can prove useful when trying to
troubleshoot setup problems.
2. After making sure that there are no test weights on the platform, press the ZERO/OFF
key again to zero out the displayed value.
3. Press the NET/GROSS key to save the zero point value. The display will show "EndC0"
momentarily, then revert back up to F16. At this time, proceed to the F17 span
calibration to complete indicator calibration.
6.3 SPAN CALIBRATION (F17)
1. While in the Setup mode, scroll to "F 17", then scroll down once using the ZERO/OFF
key to enter span calibration menu.
2. The display will momentarily show "C 1" for the span calibration, followed by a value
with one flashing digit. Place the test weight on the weighing mechanism.
3. Use the four directional keys (shown in Figure 6-1 below) to adjust the displayed value
to the actual test weight value. Increase the flashing digit by pressing the UNITS key.
Decrease the flashing digit by pressing the ZERO/OFF key. Pressing the ON/PRINT
key or the TARE key will change the position of the flashing digit.

6. If the calibration was not successful, one of the error messages below will appear. Take
the indicated action to correct the problem, then perform a new calibration.
" Err0 " - The calibration test weight or the adjusted keyed-in weight is larger than the full
capacity of the scale. Change the calibration test weight or check the input data.
" Err1 " - The calibration test weight or the adjusted keyed-in weight is smaller than 1% of
the full capacity of the scale. Change the calibration test weight or check the input data.
" Err2 " – The calibration test weight does not match the keyed-in weight. This could also
be due to an internal fault and/or damaged load cell. Or you could have simply forgotten
to place the test weight on the scale before pressing the NET/GROSS key.

APPENDIX D: NOTES ON RECHARAGEABLE BATTERY
D.1 OVERVIEW
Your scale contains two internal lead-acid rechargeable batteries connected in parallel.
Before using the scale for the first time, please charge the battery overnight.
The scale’s battery should operate for about 40 hours if left on continuously. Therefore,
greater usage times can be achieved by selecting an appropriate Auto Power Off Period
under A15 of the User Menu.
The battery can be charged while ON or OFF and the scale can be operated while it’s
charging.
D.2 WHEN TO CHARGE THE INTERNAL BATTERY
1. The best time to charge the sealed lead-acid type battery is any time the scale is not in
use. You do not have to wait for the Low Battery Indication – in fact it’s best you don’t.
Charging the battery when the scale is not in use keeps the battery “fresh” and is the
recommended way to manage your scale’s battery.
2. When the battery needs to be charged, the Low Battery Indicator will appear in the
upper left-hand corner of the display. The scale may be used for an additional 15 to 30
minutes without damage to the internal battery. If the scale is used for more than 30
minutes after a low battery indication, permanent damage may occur to the
battery and/or the battery may not accept a charge.
NOTE: When a low battery indication occurs, the scale automatically shuts off after 5
minutes of idle use.
D.3 HOW TO CHARGE THE INTERNAL BATTERY
1. Connect the charger (AC Adapter 12 VDC, 800mA) to the scale, and then plug the
charger into an AC outlet. Make sure that the AC voltage appearing at the wall
outlet matches the input voltage marked on the AC adapter.
2. After the charging period expires, unplug the charger from the AC outlet, then from the
scale. The scale is now ready for use under its own battery power.
NOTE: The charger may be left connected to the scale indefinitely without damage to
the internal battery.
D.4 HOW LONG TO CHARGE THE INTERNAL BATTERY
In general, the battery should be allowed to charge a minimum of 1.5 hours for every hour
of use.
If you discharge the battery below 50% and do not allow the proper time for charging, you
may notice a decline in the usage period. This is due to the battery’s reluctance to accept a
charge.
