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.
© Adam Equipment Company 2010 7 5.0 SETTING UP THE BALANCE 5.1 ASSEMBLING THE BALANCE Locate the balance on a solid surface, free from v ibration For PGWi models, tilt the balance on it’s side and remove the two shipping screws and nuts before use. If you need to ship the balance, replace the screws but do not over-tighten which may damage the internal mechanisms For the low capacity scales (0.001g except the PGW 753) remove the shipping protection screw and transit disc from the top of t he balance and place the plastic top pan support on the balance. Do not use excessiv e force when removing and installing the screw. Gently place the plastic pan support into the rece ptacle and secure with the supplied screw. To not over-tighten the screw. It should be finger tight only. Put the Stainless steel pan on top of the pan support Place the draught shield frame and the top cover a round the pan (for 0.001g models only) Level the balance using the adjustable feet and sp irit level Connect power to the balance For best performance, let the balance warm up for 30-60 minutes and calibrate before using Screws with nuts Label

5.2 LEVELLING THE BALANCE
After placing the balance in a suitable place,
level it by using the spirit level on the rear of t
he
balance. To level the balance turn the two
adjustable feet at the rear of the balance until
the bubble in the spirit level is centred.
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
followed by a symbol indicating the balance is in
busy mode. If the balance serial number is not
set the display will show dashes. The display
will show zeroes accompanied by the
0
symbol.
Before you start weighing, you have to wait for the balance to achieve a
stable internal temperature.
A stable sign ~ is shown when the balance is in
stable 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.
