PROCEDURE
• Make sure the balance is level and has been ON for 4 hours or more at
a stable temperature.
• Calibrate the balance twice. This helps to reduce any stresses in the
mechanics.
• To verify the accuracy of this internal calibration, place an external
mass approximately equal to the same internal calibration mass.
Record the result.
• When "INT CAL" is displayed select "YES" by pressing the [Enter] key.
The value of the internal mass set in the factory will be displayed.
• A new internal value can then be reset to display the external mass
value correctly. If the reading for the external mass is greater than the
actual value of the mass then reduce the internal mass value by the
difference. Enter this reduced value when prompted by the display.
For example, if the internal mass previously set is 520.054g and the
display reads 500.050g when using an external mass of 500g, then
reduce the internal mass value by 0.050g. Enter the new revised value
of 520.004 (in place of 520.054g) when prompted. The adjustment can
be done for up to ±100mg.
• Repeat the calibration and check the value of the external mass again.
• Repeat this procedure until the value displayed is correct for the mass
used.
• Press [Esc] to return to normal weighing.

13.6 PASSCODES

To enable the security features in this balance it is necessary to set
passcodes. There are 2 passcodes called Operator Passcode and Supervisor
Passcode. The Operator Passcode allows an authorised user to operate the
basic weighing functions of the balance but will not allow access to the
Supervisor Menus if the Supervisor Passcode has been set.
To change or disable a Passcode it will be necessary to enter the current
passcode.
Press [Enter] when "PASSCODES" is displayed to enter this section.
