1. Introduction
The user-interface for the iSonic consists of a graphic LCD and a 6-key keyboard. With
this interface, the user can configure the entire set-up of the instrument and select
different information screens whilst the unit is in measurement mode.
After a power-up, the iSonic will always start the measuring process, this is called RUN
mode. When a user presses the “M” key on the keyboard, the unit will enter a
configuration mode, this is called MENU mode.
The interface for the user has been made to consistently work as follows:
The ‘M’ button either, when in RUN mode, calls up the menu, or, when in MENU
mode, takes the user a menu level up.
The ‘OK’ button either starts the editing of a value or confirms a value. When editing
a value, the ‘M’ key acts as a abort key, the value remains unchanged.
When editing a value, the Up and Down arrows (▲▼) either select options for that
value (eg. ON/OFF), or for numeric values selects the next digit value.
When in menu selection mode the Up and Down arrows (▲▼) select the next menu
entry.
When editing a value, the Left and Right arrows (◄►) either select options for that
value (for instance: ON/OFF), or for numeric values select the digit next to the one
currently selected.
When in MENU mode, the Left and Right arrows (◄►) select the next menu entry.
The entire menu system is shown in the attached, “Appendix 2 – Total Menu System”
Please note that the RUN mode is not always entered after a power-up; if unit has
detected a faulty configuration, the MENU mode is automatically entered, requiring a user
to configure the unit again.
Not all configuration data is available through this interface, certain settings such as
modem configuration, telephone numbers and the likes are only accessible through the
PC configuration program. The LCD/Keyboard interface is mainly provided for quick field
configuration changes and it is recommended to use the PC interface for initial
configuration of a unit. The reasons for this is two fold:
1. The PC configuration program is easier to work with and gives a more
comprehensive overview of a configuration.
2. The PC configuration program performs numerous checks and does not allow invalid
configurations. This is contrary to the menu system where a user is able to enter an
invalid configuration. The iSonic does perform certain checks on the configuration but
not all situations are tested.
