• 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 100.054g and the
display reads 100.050g when using an external mass of 100g, then
reduce the internal mass value by 0.050g. Enter the new revised value
of 100.004 (in place of 100.054g) 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.
OPERATOR
Enter the current passcode (OLD) first then enter a new
passcode if desired. A passcode set to zero will disable
the security feature and allow unlimited access.
SUPERVISOR First enter the current passcode (OLD) and then enter a
new passcode, if desired. A passcode set to zero will
disable the security feature and allow unlimited access.
