4.2.4. Battery Condition Icon
On all the main LeveLine
®
Meter screens, a battery condition icon is displayed in the top left
corner. The icon shows full when the batteries are fresh, and gradually empties as the
batteries are used. When the batteries need replacing, the empty battery icon will flash on
and off. If you ignore this, the Meter will automatically switch itself off when the battery
voltage becomes too low for reliable operation.
When using rechargeable batteries, the battery icon will not show completely full, even with
freshly charged cells. This is due to the fact that rechargeable batteries are only rated at
1.2V per cell compared to 1.5V per cell for alkaline batteries. This indication does not affect
battery life. The icon will simply sit at the ¾ full mark for a longer period of time.
4.2.5. Battery Saver Functions
The LeveLine
®
Meter is designed to switch off automatically if you do not touch any of the
keys for 30 minutes.
The display on the LeveLine
®
Meter incorporates a white backlight to improve visibility in
low-light conditions. As on a mobile phone, the backlight switches on each time a key is
pressed and stays on at full brightness for a short time before fading to half brightness then
switching off.
During normal operation, if you want to activate the backlight without changing the Meter
function, simply press the
ESC
key.
4.3. Overview of the Operating System
The operating software in the LeveLine
®
Meter has been designed for simple, intuitive use.
If you are used to operating a mobile phone or programming audio/visual equipment using
a remote control, you should feel at home with the familiar up/down left/right arrow shaped
navigation keys and central
OK
key.
The tree structure behind the
MENU
key should also be very familiar. Each item on the
menu leads to a sub menu and then either on to further menus or final choices. Each
branch of the menu system is navigated using the arrow keys. At each point, selections can
be made by either pressing the
OK
key or the right arrow key.
To reverse along a branch of the menu system, use the
ESC
(escape) key or left arrow key.
After a short time, you should be able to navigate around the entire menu system at speed
using just the four arrow keys. If, at any time, you leave the Meter in one of the sub-menu
screens, it will automatically back out to the main operating screen after 15 seconds.
4.4. Initial Switch On and Clock Setup
To switch the meter on or off, briefly press the red key.
Do not hold it down.
The meter
contains a real-time clock. When switching on for the first time, you must set the clock. The
first screen you will see is the Time & Date Setting Screen.
