1Introduction
This document is a user manual for the LCD interface for instrument TunnelTech
500/700, which helps to navigate the menus and sub menus using the unit’s
keypad membrane.
Keypad Membrane
Using the keypad buttons the user can access and navigate the menus and sub
menus. The device includes the following buttons:
Exit to main measurements screen from any menu position
Select/Apply
Scroll up/Increment
Scroll Down/Decrement
Pressing the “Exit” or “Enter on
Exit” in any menu returns the
user to the previous menu
screen, while the “Mode” key
will bring the user back to the
Measurements screen of the
main menu.

Welcome Screen
The welcome screen displays “Codel – FM” (manufacturer’s name) and
“TT500/700 SERIES” (instrument’s name).
The welcome screen is closely followed by the measurement initialisation screen.
Depending on if the attached peripherals have been powered down, the current
state of the attached devices will be displayed.
After initial setup, the device displays the current measurement for an attached
device:
If the display unit is unable to communicate with the attached peripheral the screen
will display a communications fault. This will show an “E-Cell Comm Fault” or “Vis
Comm Fault” respective of where the fault resides.
If no devices are configured or have been disabled, the screen will display a
warning message to alert the user that no devices are attached.

The Instrument has following main menu options:
Acts as main screen for data observation and allows the user to select which
measurand data is to be displayed.
Allows the user to view more in-depth diagnostic data for each channel available
on the device, as well as set some status information for peripheral measurement
devices.
Allows the user to alter the setup of the device.

3Measurements
The measurements screen acts as the main observation screen, displaying the data
collected from the attached peripherals.
From the main measurements screen pressing button brings up the channel
selection menu which allows the user to select which attached channel should be
displayed on the main screen.
Select Channel
The channel selection menu displays all the currently enabled peripheral
measurand devices. The displayed measurements are extracted directly from the
attached peripherals and are dynamically updated on the display.

If the peripheral PCBs on the
device are different, or not
installed the menu results
shown in Figure 3 could be
different.
Missing menu options could
also be caused by peripheral
boards being disabled. See

The diagnostic status menu system can provide for the user, a constant update on
the peripheral flags which describe the current condition the device is in.
The menu is split into two Submenus, containing E-Cell and Vis Status options.
The Status menu has two sections “Mode status” and “Performance Status”
The flag is a Boolean with each flag being represented by a ‘0’ or a ‘1’.
