this equipment. Failure to comply with these warnings could result in personal injury
and/or property damage. Retain all instructions for future reference.
Verify that the AC adapter’s input voltage range and plug type are compatible with the
local AC main power supply.
Make sure that the power cord does not pose a potential obstacle or tripping hazard.
Do not position the balance such that it is difficult to reach the power connection.
The balance is for indoor use only. Do not operate the equipment in hazardous or
unstable environments.
Operate the equipment only under ambient conditions specified in these instructions.
Do not drop loads on the pan.
Use the balance only in dry locations.
Disconnect the equipment from the power supply when cleaning.
Use only approved accessories and peripherals.
Service should only be performed by authorized personnel.
Intended Use

2. INSTALLATION
2.1 Select the Location
Avoid heat sources, rapid temperature changes, air current or excessive vibrations. Allow sufficient
space.
2.2 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.
2.3 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.
2.4 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.
