Carefully remove your PX balance and each of its components from the package. The included components vary
depending on the balance model (see the list below). Save the packaging to ensure safe storage and transport.
Please read the manual completely before installing and using the PX balance to avoid incorrect operation.
Components included:

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 Figure 2-1 for leveling.

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.

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-

When the PX balance is first installed, or when it is moved to another location, it must be calibrated to ensure
accurate weighing results. PX balances are classified into two categories, InCal models and ExCal models. InCal
models have a built-in calibration mechanism which can calibrate the balance automatically and does not require
the use of external calibration masses. If preferred, InCal models can also be manually calibrated with external
masses. ExCal models are calibrated with external masses. Make sure to have the appropriate calibration masses
available before beginning calibration.
