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.
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-through) serial cable.
Use the USB port to connect to a computer with a USB 2.0 Type A to Type B cable.
Interface connections on the rear of the balance

USB Used to connect to PC only
RS232 Used to connect to PC or Printer
For Connecting, Configuring and Testing the Printer / Computer Interface, see the Printing section.
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.
