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 PR balance has a level bubble in a small round window
beside the display.
To level the balance, adjust the 2 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 PR balance has an RS232 port.
Use the RS-232 port to connect either to a computer or a printer with a standard (straight-through) serial
cable.
Interface connections on the rear of the balance

2.5 Initial Calibration
