TT-830 Bench Scale Service Manual
There are three levels of TT-830 setup you can access through the front
panel:
User level
The first level is the User level. These are the most commonly
changed values and parameters that you will use in the course of
operating the TT-830.
Configuration level
The second level is the Configuration level. These items deal with
some of the basic functions of the TT-830 and do not need to be
accessed very often.
Calibration level
The third level is the Calibration level. This section will need to be
accessed only when the scale is being calibrated, or if you change
scale capacity or division size.
A different password is needed to access each level. Once you access the
level you want, the display presents a series of soft key choices. By pressing
the appropriate soft key and following text prompts on the display, you can
set up your TT-830 to suit your needs.
Following are the instructions you need to access the setup of the TT-830.

until the TT-830 beeps. . . The display asks for a password and
