10.0 CALIBRATION
The PW series can only be calibrated using either an internal mass (default
method) or an external mass (if setup by the user). See the User Parameters
section.
10.1 MANUAL CALIBRATION
Pressing the [Cal] key will start calibration. Calibration can also be initiated by
a change in internal temperature or a set time period as determined by the
user (see section 13.5).
10.1.1 Calibration using Internal Calibration mass
• Check the display is at zero. Tare if necessary
• Calibration will begin automatically. When calibration is complete the
balance will return to weighing.
10.1.2 Calibration using External Calibration mass
• Pressing [Esc] will abort the calibration at any time
• Press the [Cal] key
• The display will show the balance setting a new Zero condition by
showing “LOAD 0”. Make sure the pan is empty then press the [Enter]
key to continue
• The display will show the busy symbol and then will ask for the value of
the calibration mass to be entered sounding a beep and displaying the
default calibration mass. For example, “CAL MASS 100,000 g” where
