The (

SPACE
) and key ( . ̅ ) button functions depend on context. When editing a floating point number,
the key ( . ̅ ) inserts a negative sign if the editing cursor is at the start of the number and negative
signs are allowed. Otherwise it moves the decimal place to the current cursor location. The (
+
SPACE
)
key inserts a positive sign if the cursor is at the start of the number; otherwise it enters a space.
For non-floating point numbers, these keys usually increment or decrement the current value by 1.
When editing the month field of a date, the (

Instrument Status Light Buttons (4)
Located in the top left corner, these lights indicate the status of the instrument as a whole.

A red light indicates that the instrument has a major failure and is not functioning.

An orange light indicates there is a minor problem with the instrument, but the instrument may
still take measurements reliably.

A green light indicates that the instrument is working and there are no problems.
In the case of an orange or red light enter the Status Menu to find which components are failing
(refer to Section 3.4.4) or pressing the orange or red light when illuminated will bring up a pop up
box with a full list of current faults.
Pressing the green status light button at any time will cancel any open edit box or menu and return
the user to the home screen.
If no instrument status lights are on and the keypad is backlit, this indicates that the instrument is
running the bootloader. The screen will also indicate that it is in the bootloader menu.
3.3.2 Home Screen
The home screen is composed of seven parts: readings (1), error/status line (2), instrument activity
line (3), selection buttons (4), time/date (5), concentration units (6) and USB status (7).
