Installation
Preparation
This product is intended for indoor use.
Select a level, rigid work area that is free from drafts and
vibrations (i.e. away from doors, windows, air conditioning
and heating vents).
The line voltage to the balance should be reasonably con-
stant (+/-10%) and free from fluctuations.
Position balance to allow the removal of the power adapter
plug from the wall outlet. It is not advisable to use an outlet
that is shared with fluorescent fixtures or other electrical
equipment that draws current in an inconsistent manner.
Do not locate the balance near magnetic materials, or near
instruments that incorporate magnets in their design. Avoid
areas that experience extreme highs, lows or fluctuations in
room temperature. Excessive temperatures that may affect
balance operation and accuracy are 1) above 105°F (40°C)
and 2) below 60°F (15°C).

Setup
Carefully remove the balance and all accessories from the
carton. There are no tie-downs; however there may be pack-
ing materials under the pan support (square-pan models only).
LEVELING THE BALANCE
1. The leveling feet are located on the bottom of the balance.
Do not turn the balance over. Viewing the balance from
above, turn all leveling feet counterclockwise until the feet
are fully retracted into the balance base.
2. Note the position of the bubble on the leveling vial.
For maximum weighing accuracy, the bubble should be
located inside the black ring. Some adjustment will likely be
necessary.
3. Begin with the foot that is opposite of the location of the
bubble and turn clockwise until the bubble is moved into
the black ring. If necessary, repeat this step with the other
leveling feet until the bubble is positioned in the center of
the black ring.
4. Avoid extending the level feet too far. If it seems necessary
to do so, it is likely that the tabletop is not level. Check the
surface on which you have placed the balance; it may be
necessary to choose another location.
The bubble moves TOWARD a foot when that foot is
turned CLOCKWISE. The bubble moves AWAY from a
foot when that foot is turned COUNTERCLOCKWISE.
POWERING THE BALANCE
WARNING
Verify that you have received the proper voltage
power supply for your country of use!
Insert the power cord into the receptacle located at the back
of the balance and plug the power adapter into a wall outlet.
The display will perform a quick test in which all segments are
briefly illuminated and display “stabilizing” for 30 seconds.
INITIAL WARM-UP PERIOD
After the initial power-up, it is necessary to allow a minimum of
60 minutes for the balance components to become warm
and for the internal temperature to stabilize.

!
Memo:
Note

It is not necessary to unplug your balance from the power
source when it is not in use. It is advised to leave the unit
plugged in so that all components are warm and the balance
is ready to weigh at any time. If you wish, the display can be
turned off to save the segment life, by simply pressing the
Display On/Off button.
WEIGH PAN INSTALLATION
WARNING
Mishandling the balance weigh pans can
cause serious mechanical damage!
The balance weigh pan engages critical and delicate
mechanical components inside the balance. Please observe
the following precautions when handling the weigh pans:
1. Do not apply manual pressure to the weigh pan at any time.
2. Do not bump the pan.
3. Do not drop objects onto the pan.
4. Do not attempt to clean or vigorously wipe the pan while it is
installed on the balance.
ROUND-PAN MODELS
Balances with 3.5” or 4.5” round pans feature a weigh pan
assembly that consists of an aluminum pan and an impact pro-
tection ring that helps to shield the weigh pan from lateral
shocks. (For models with 6” pans, simply place pan on pan
stem.)
1. Place the impact ring on the balance first.
2. Center the weigh pan over the impact ring and gently slide
or twist (do not push) the pan onto the pan stem.
3. When removing the pan for cleaning, remove the impact
ring first and then pull the weigh pan straight up and off
(pulling the pan at an angle could result in mechanical
breakage).
SQUARE-PAN MODELS
Simply place the square top-pan on the pan support.
You’re ready to begin weighing!

Display and Keypad
The balance features an integrated display/keypad. The
high-contrast LCD display simultaneously provides alpha and
numeric information for ease in setup and accuracy in inter-
pretation of results.
DISPLAY

Software Layout
The balance has a wide variety of modes of operation and set
up parameters for different weighing applications. Parameters
can easily be changed by scrolling through the options and
choosing the desired selection. The different weighing modes
include: basic weighing, animal weighing, statistics, counting,
check weighing and specific gravity calculating. The default
mode is basic weighing. When a mode is turned ON, the mode
name will appear in the lower left corner of the display.
Basic weighing = WEIGH Counting = PCS (for pieces)
Animal weighing = ANIMAL Check Weighing = UNDER, OK or OVER
Batch Weighing = Prompts Specific gravity = SPC GRAVITY (and prompts)
Statistics = SAMPLES
Modes must be turned Off to return to basic weighing or
entering a new mode will turn the previous mode Off.
Setup parameters for optimizing the balance for your specific
needs and conditions include: weighing unit, environmental set-
tings, serial interface settings and Good Laboratory Practice

Calibration
Your balance was calibrated at the factory; however, it is nec-
essary to re-calibrate upon setup and on a regular basis
thereafter. The factory recommendation for calibration is
once per week using the maximum permissible weight stan-
dard. Reasons for more frequent calibration include 1) moving
the balance, 2) organizational procedures, 3) special sam-
ples/applications which require documented calibration
time/date stamp.
Your balance may be calibrated in the External mode or the
Manual mode. Both use an external mass standard. In the
external mode the balance will recognize the calibration
weight as one of the permissible weight values, whereas in the
Manual mode an exact certified value of the calibration
weight is entered.
