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.

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.
