SETUP MODE
The Setup Mode allows the user to set all needed character-
istics of the meter.
To enter the mode, press the SETUP key and
enter the password when the device is in idle or
control mode.
If the correct password is not entered, the user can only view
the setup parameters (except for passwords) without modify-
ing them (and the device remains in control mode). An
exception is certain setup items, or flags, which can activate
special tasks, when set and confirmed.
To each setup parameter (or setup item) is assigned a three
characters (one letter followed by two digits) setup code which
is entered and displayed on the secondary LCD. The first
character identifies the group of setup items, while the two
digits identify the particular item within that group.
The setup codes can be selected after password is entered
and CFM key is pressed. When CFM is pressed, the current
setup item is saved on EEPROM and the following item is
displayed.
