USB Port Connection
The MicroLite interfaces with the computer via any of its USB Host ports. In order to be
detected by the computer and by the MicroLab Lite software, the USB driver must
first
be installed. USB driver installation is part of the software installation (see section
Software Installation on page 8).
MicroLite LCD Status when Connected to USB
The USB connection status is always displayed on the MicroLite LCD when connected
or disconnected from a USB port.
The LCD flashes
USB ON
once when connected and flashes
USB OFF
once when
disconnected from the USB port.
The logge
r LED (located adjacent to the logger’s USB connector) also lights up green
when connected to the USB port.
If the MicroLite is in
Run
mode when connected to the USB port, the LCD will only
display the current temperature reading and will not scroll through the other readings.
If the MicroLite is in
Stop
mode when connected to the USB port, the LCD will display
STOP
. If the logger had recorded an alarm during the previous data logging session,
then the LCD will also scroll through the alarm durations.

The MicroLite Battery
The MicroLite runs on a standard 3V CR2032 lithium battery.
The battery maintains the MicroLite’s Real-Time Clock (RTC). The logger’s time/date
settings are synchronized with the PC when you perform a Setup. Removing the battery
will return
the logger’s time/date settings to the default of 01 Jan 2004.

Battery Level
The MicroLite battery level indication is provided in the MicroLab
Lite software’s Setup
dialog (see page 10).
The MicroLite battery
’s maximum lifespan is approximately two years. This long battery
life is achieved by the MicroLite putting itself
to sleep
between data recordings. While in
sleep mode, the data logger consumes a minimal amount of power.
MicroLite will
wake up
for a few micro-seconds whenever it has to record a data sample
or display new data on the LCD screen.
