3.0 UNPACKING THE BALANCE
Remove the balance from the packing by carefully lifting it out of the box. Inside the box
you will find everything needed to start using the balance.

4.0 LOCATING THE BALANCE
•The balance should not be placed in a location that will reduce
the accuracy.
•Avoid extremes of temperature. Do not place in direct sunlight or
near air conditioning vents.
•Avoid unsuitable tables. The table or floor must be rigid and not
vibrate.
•Avoid unstable power sources. Do not use near large users of
electricity such as welding equipment or large motors.
•Do not place near vibrating machinery.
•Avoid high humidity that might cause condensation. Avoid direct
contact with water. Do not spray or immerse the balances in water.
•Avoid air movement such as from fans or opening doors. Do not
place near open windows or air-conditioning vents.
•Keep the balance clean. Do not stack material on the balances
when they are not in use.

5.0 SETTING UP THE BALANCE
5.1 ASSEMBLING THE BALANCE
•Locate the balance on a solid surface, free from vibration
•For the low capacity scales (0.001g) remove the shipping protection screw and transit
disc from the top of the balance and place the plastic top pan support on the balance. Do
not use excessive force when removing and installing the screw.
•Gently place the plastic pan support into the receptacle and secure with the supplied
screw. Do not over-tighten the screw. It should be finger tight only. Put the Stainless steel
pan on top of the pan support
•NOTE: The plastic pan support can be fitted in 2 orientations, place it in the orientation
that has the smallest gap between the front edge and the display.
•Place the draught shield frame and the top cover around the pan (for 0.001g models
only).
•Level the balance using the adjustable feet and spirit level.
•Connect power to the balance.

•For best performance, let the balance warm up for 15 minutes and calibrate before
using.
5.2 LEVELLING THE BALANCE
After placing the balance in a suitable place,
level it by using the spirit level on the rear of the
balance. To level the balance turn the two
adjustable feet at the rear of the balance until
the bubble in the spirit level is centered.
5.3 WARM-UP TIME
Attach the power supply cable to the connector
on the rear of the balance. Plug the power
supply module into the mains. The display will
indicate the balance serial number (if set) and
the software revision number followed by the
capacity of the balance.
Next the balance will run a self-test by
displaying all segments and then will show
zeroes accompanied by the zero symbol. If the
balance serial number is not set, the display will
show dashes.
Before you start weighing, you have to wait for the balance to achieve a stable internal
temperature. Typical initial warm-up time suggested for a balance already at room
temperature is about 15 minutes.

A stable sign ~ is shown when the balance is instable
condition. It will turn off if the balance is not stable.
Exact zero is shown when the “0“ symbol is on to
the left of the display area.
6.0 DISPLAY
The LCD has several areas-
- A large 7 digit area to display the weight with symbols for
common weighing units on its right and symbols for zero, tare (Net) and stability on
the left.
- A 10 digit area which allows a large amount of flexibility for displaying text
messages concerning menus, operation and
errors, for example to display the current weighing mode or to guide the user
through processes such as density determination.
