1 General Information and Warnings
1.1 About this Manual
This manual is divided into chapters by the chapter number and the large text at the top
of a page. Subsections are labeled as shown by the 1 and 1.1 headings shown above.
The names of the chapter and the next subsection level appear at the top of alternating
pages of the manual to remind you of where you are in the manual. The manual name
and page numbers appear at the bottom of the pages.
1.1.1 Text Conventions
The keys used to interface with the PS-500 are located on the front panel of the
indicator. The keystrokes are shown in BOLD incased between brackets. (e.g. [ZERO])
Displayed messages appear in LCD format (e.g. setup) type and reflect the case of
the displayed message.
1.1.2 Special Messages
Examples of special messages you will see in this manual are defined below. The
signal words have specific meanings to alert you to additional information or the relative
level of hazard.
CAUTION!
This is a Caution symbol.
Cautions give information about procedures that, if not observed, could result
in damage to equipment or corruption to and loss of data.
ELECTRICAL WARNING!
THIS IS AN ELECTRICAL WARNING SYMBOL.
ELECTRICAL WARNINGS MEAN THAT FAILURE TO FOLLOW
SPECIFIC PRACTICES OR PROCEDURES MAY RESULT IN
ELECTROCUTION, ARC BURNS, EXPLOSIONS OR OTHER HAZARDS
THAT MAY CAUSE INJURY OR DEATH.
NOTE: This is a Note symbol. Notes give additional and important information, hints
and tips that help you to use your product.

4 PS1000/2000 User Instructions
1.2 Warnings
lRead all operating instructions carefully before use.
lAvoid lengthy exposure to extreme heat or cold. Your scale works best when
operated at normal room temperature. Always allow the scale to acclimate to
a normal room temperature before use.
lAllow sufficient warm up time. Turn the scale on and wait for a few minutes if
possible. This will give the internal components a chance to stabilize before
weighing.
lThese electronic scales are precision instruments. Do not operate near an
in-use cell phone, radio, computer or other electronic device. These devices
emit RF and can cause unstable scale readings.
lAvoid using in heavy vibration and airflow conditions.
lRead the weight shortly after loading. The output of the loadcell and A/D
may be a little influenced after weight sits for a long time.
1.3 EMC Compliance
The following warning may be applicable to your machine.
United States
This equipment has been tested and found to comply with the limits for a Class A digital
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference when the equipment is operated in
a commercial environment. This equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in accordance with the instruction
manual, may cause harmful interference to radio communications. Operation of this
equipment in a residential area is likely to cause harmful interference in which case the
user will be required to correct the interference at his own expense.
DANGER: FOR YOUR PROTECTION, ALL MAINS (110V OR 230V)
EQUIPMENT USED WHERE DAMP OR WET CONDITIONS MAY OCCUR
MUST BE SUPPLIED FROM A CORRECTLY FUSED SOURCE AND
PROTECTED BY AN APPROVED GROUND FAULT PROTECTION
DEVICE (RCD, GFCI ETC).
DANGER: RISK OF ELECTRICAL SHOCK. BE SURE TO UPLUG THE
INDICATOR BEFORE REMOVING THE COVER OR OPENING THE UNIT.
REFER TO QUALIFIED SERVICE PERSONNEL FOR SERVICE.
CAUTION!
This is a Class A product.
In a domestic environment this product may cause radio interference in which
the user may be required to take adequate measures.

PS1000/2000 User Instructions 5
Canada
This digital apparatus does not exceed the Class A limits for radio noise emissions from
digital apparatus set out in the Radio Interference Regulations of the Canadian
Department of Communications.
Le présent appareil numérique n’émet pas de bruits radioélectriques dépassant les
limites applicables aux appareils numériques de la Classe A prescrites dans le
Règlement sur le brouillage radioélectrique edicté par le ministère des
Communications du Canada.
1.4 Routine Maintenance
1.5 Cleaning the Indicator
1.6 Sharp Objects
Do not use sharp objects such as screwdrivers or long fingernails to operate the keys.
IMPORTANT: This equipment must be routinely checked for proper operation
and calibration.
Application and usage will determine the frequency of calibration required for
safe operation.
Always turn off the machine and isolate from the power supply before starting
any routine maintenance to avoid the possibility of electric shock.
Table 1.1 Cleaning DOs and DON’Ts
DO DO NOT
Wipe down the outside of standard products
with a clean cloth, moistened with water and
a small amount of mild detergent
Attempt to clean the inside of the indicator
Use harsh abrasives, solvents, scouring cleaners or
alkaline cleaning solutions
Spray the cloth when using a proprietary
cleaning fluid
Spray any liquid directly on to the display window

This chapter introduces indicator mounting, display and keypad operation in normal
weigh mode.
3.1 Indicator Mounting
The PS-500 is supplied with an ABS plastic bracket. Wall mount vertically or bench
mount horizontally depending on your needs.

3.3 Display
The PS-500 indicator utilizes a 7 segment LCD (Liquid Crystal Display) providing the
weight and system information.
Arrows will illuminate to designate the current mode.

The current live weight is being displayed when the arrow flashes. The current weight is
locked when the arrow does not flash.
NET Indicates net mode and the tare weight is not 0.
lb Indicates the current unit of measure is lb.

3.4 Keyboard
The keyboard consists of four keys, some of which have multiple functions.
Figure 3.2 SBI-521 Keypad
Table 3.2 Function of the Keys (Normal Working Mode)
Key Function
If this key is only set for HOLD (P2=0), press to enter or exit the HOLD mode.
If this key is only set for PRINT (P2=1), press to output the data according to P4 setting.
If this key is only set for HOLD and PRINT (P2=2), press to output data according to P4
setting and hold the current weight.
Choose weighing units; lb, kg, lb:oz
Note: The weighing units that can be used are restricted by display division, and
calibration weight unit (restricted by P8, P9, and P10)
For example, if the calibration unit is kg; calibration display resolution is 50kg (that
means: P8=5, P9=0, P10=0). If the UNIT key is pressed to choose weighing units, lb or
lb:oz are not allowed to choose since the display resolution of 100lb or 2000oz is not
available to this indicator.
Tare function
This function can be activated only when the scale is in stable mode and the gross
weight is not a negative value.
Power on
Zero function: When the weight is within zero range, it will activate as ZERO function
and clear the tare weight. When the weight is not within the zero setting range (P13),
the scale will show 0----- (zero point is over the setting range) or 0_____ (zero is below
the setting range).
Power off
ignore modification
Prepare to exit from current working mode

3.6 Hold Function
HOLD function can be used to freeze a displayed number. In this mode, the scale can
capture a dynamic number, hold a stable number, or average a unstable number and
then HOLD (freeze) this number temporarily for the user to view or record.
The HOLD function can be used in normal weighing mode, counting mode and percent
weighing mode. After entering HOLD mode, the speed of A/D converter can be
increased to 80Hz (if USER-HOLD-AD.H.SPD is set to YES) from original 10Hz for
some dynamic weighing applications.
It is possible to weigh restless weighing samples such as live animals or moving objects
within the hold function. The indicator provides special mode settings to accommodate
weight movements.
3.6.1 Access the Hold Mode
To enter the HOLD mode, press the [HOLD] key while in the normal weighing mode.

PS1000/2000 User Instructions 15
4 Setup Mode
To set up the indicator, you must first enter the appropriate menu mode. The front panel
keys become directional navigators to move around in the menus. See Table 4.1 for
details.
4.1 Entering the Setup Menu

and use the [HOLD/PRINT] key to shift the flashed position.
The parameter will be designated in the following format:
PN.x or PNN.xx - P is parameter; N or NN is the parameter number; x or xx is the choice
within the parameter. Refer to Table 4.2 for parameters and the options for each
parameter.
