3.1 Select the Location
Avoid heat sources
3.2 Leveling
Be sure the balance is level before it is used or after its location is
changed.
The PX balance has a level bubble in a small round window beside
the display.
To level the balance, adjust the 4 leveling feet until the bubble is
centered in the circle.
Please refer to the right figure for leveling.
3.3 Connecting Power and Acclimatising the Balance
Connect the DC output connector to the power receptacle on the rear of the balance.
Then connect the AC adapter plug to a suitable electrical outlet.
Acclimatising
It is suggested that the balance should not be used until it has been connected to
power and acclimatised to the environment for a certain period of time. In the case of a
balance with the precision above 0.1 mg, the acclimatisation time should be 1.5 hours;
in the case of balance with the precision of 0.01 mg, the acclimatisation time should be
more than 4 hours.
3.4 Connecting the Interface
The PX balance has two data interfaces, RS232 and USB.
Use the RS-232 port to connect either to a computer or a printer with a standard
(straight-through) serial cable. Use the USB port to connect to a computer with a USB
2.0 Type A to Type B cable.
