CHAPTER 1: INTRODUCTION TO THE PALLET RUNNER 3000 PALLET JACK SCALE

The PALLET RUNNER 3000 Series Scale is a general purpose, industrial grade pallet weighing

scale. Featuring complete portability utilizing 2-6 Volt internal batteries, push button tare, and an

easy to use piece-counting function.

The display type, enclosure type and scale capacity information can be found in Table 1-1.

All PALLET RUNNER 3000 model scales are factory tested and calibrated prior to delivery.

Therefore calibration is not required after unpacking the scale. A small amount of preparation is

necessary before the scale can be used. You will find this information in Chapter 2. Please read

these instructions carefully and completely, prior to using the scale.

Prior to using the scale, please read this user’s guide carefully and completely. Store the manual

in a safe and convenient place so it will be available if you have questions concerning the

operation of the scale.

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.

CHAPTER 3: OPERATION

3.1 DISPLAY

The PALLET RUNNER 3000 utilizes a 6 digit LCD (Liquid Crystal Display) to display the

weight and system information Table 3-1 summarizes the display

annunciators.

MEANING

0

Better known as the “Center of Zero” annunciator, this light is active

whenever the displayed weight is within ± 0.25 divisions of true zero.

Indicates that the scale is displaying net weight.

Indicates that the scale is displaying gross weight.

Indicates that a tare weight has been established in the system.

lb, kg, pcs

Indicates the unit of the displayed weight. .

This light is on whenever the scale is stable.

Indicates that the battery voltage is too low for normal operation. Use the AC

adapter to re-charge the battery.

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.

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 5: SCALE CONFIGURATION

5.1 SCALE CONFIGURATION OVERVIEW

The scale contains two main setup menus: The User (“A”) menu - which configures the

serial communication port and enables some user options - and the Factory Setup (“F”)
