10.0 CALIBRATION

The PGW XXXe series can only be calibrated with an external mass. The

PGW XXXi series can be calibrated with either an internal mass (default

method) or an external mass (if setup by the user to do this). 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).

• Pressing [Esc] will abort the calibration at any time

• 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

• Check the display is at zero. Tare if necessary

• Press the [Cal] key

showing “LOAD 0”. Make sure the pan is empty then press the [Enter]

key to continue

• The balance will then show the value of the calibration mass required

sounding a beep, for example “LOAD 1000 g”

• Place the mass on the balance. Press [Enter] to continue

• The display will show the busy symbol and after calibration is complete

it will display “UNLOAD” sounding a beep. Remove the weight. Another

beep will be heard confirming the unloading action. The balance will
