CHAPTER 5 - SETUP
Chapter 5 covers firmware settings to prepare the controller for calibra-
tion and operation. User and service personnel should be familiar with
the information in this chapter before going through the setup proce-
dures. Alternatives to these procedures are not recommended.
Keypad Functions (See
Fig. 5-1)
FIG. 5-1 FRONT PANEL
Zero • Used in Gross mode to zero the display to within the tolerance
level.
• This function can be used as many times as desired as long as the
total does not exceed the value entered as the zero tolerance.
• The zero key is also used to exit a menu after entering number(s)
without changing the original number. For example - when entering
a Span value (18), the user decides that the original number (15) is
OK. By pressing the Zero Key you can exit the menu without
changing the original number (15), even though you have typed
new numbers and they appear on the display.
Mode • In standard controllers, the mode key toggles between gross and net
weight.
• In controllers with any one or all of the mode options (Total Mode,
Peak Hold Mode, or Rate of Change Mode) installed the mode key
toggles between gross/net weight and the option(s).
NOTE: To order Total, Peak or ROC options, contact your local Hardy Representative or
call/FAX/E-mail Hardy Instruments, Sales Department.

Tare button is pressed and places it in the tare register setting the

Vessel weight) and Gross weight (e.g. vessel weight + material
