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

Stability Indicator. This icon is illuminated when the balance

has stabilized, indicating that the displayed weight is your final

result.

Weigh Units. The current selected weigh unit is displayed. The

balance will keep two weigh units resident for ready use at all

times. Press "Select" to toggle between the two resident

weigh units. (Factory default is grams.) See page 12 for a

complete list of weigh units, their display abbreviations and

how to change the current weigh units.
