EL-USB-3
Voltage USB Data Logger
This data logger measures and stores up to 32,510 voltage readings over a 0-30V d.c. measurement range. The user can easily set up
the logging rate and start time, and download the stored data by plugging the module straight into a PC's USB port and running the
purpose designed software under Windows 98, 2000 or XP. The data can then be graphed, printed and exported to other
applications. The data logger is supplied complete with a long-life lithium battery. Correct functioning of the unit is indicated by
flashing red and greenLED. The data logger featuresapair of screw terminals and is is supplied completewitha set of measurement
leads terminating in crocodile clips.

LED FLASHING MODES
EL-USB-3 features a red and a green LED.
The LEDs on an EL-USB-3 will flash in one of the following ways, assuming alarm latching is turned off (exact
timings to be confirmed).
- Green single flash, Logger primed and ready to start.
every 30 seconds
- Green single flash, Logging in progress, last stored value OK
every 10 seconds
- Red single flash, Logging in progress, the last stored reading is equal to or the low alarm level
every 10 seconds (If latching is turned on, then a stored value is equal to or exceeds the low alarm level)
- Red double flash Logging in progress, the last stored reading is equal to or exceeds the high alarm level
every 10 seconds (If latching is turned on, then a stored value is equal to or exceeds the high alarm level)
- Green single flash, Low battery, logging in progress, the last stored value OK
every 20 seconds
- Red single flash, Low battery, logging in progress, the last stored value is equal to or exceeds the low alarm level
every 20 seconds
- Red double flash, Low battery, logging in progress, the last stored value is equal to or exceeds the high alarm level
every 20 seconds
- Green double flash, Logger is full, last stored value OK
every 20 seconds
- Red/Green single flash, Logger is full, last stored value is equal to or exceeds the low or high alarm level
every 20 seconds,
alarm latching turned on
- No LEDs flash LEDs disabled during configuration to save battery power and increase logging duration.
or
Battery dead.
exceeds
By default latching is disabled, so the red LED will continue to flash, even after the logged voltage has returned to
normal. The red LED will effectively have latched into its alarm condition. This feature ensures that the user is
notified that an alarm level has beenexceeded,withoutthe need to download the data from the logger.
Latching can be turned on via the control software. The red LED will then no longer continue to flash after the
logged voltage has returned to normal. Instead,thegreenLED will then flash.

BATTERY REPLACEMENT
Werecommendthat you replace the battery every 12 months, or priortologgingcritical data.
The EL-USB-3 does not lose its stored readings when the battery is discharged or when the battery is replaced; the
data logging process will however be stopped and cannot be re-started until the battery has been replaced and the
logged data has been downloaded to PC.
Only use 3.6V 1/2AA lithium batteries. Check with your supplier that thebatteryyouare ordering is 'press fit' and
is not fitted with solder tags. Before replacing the battery,removetheEL-USB-3 from the PC.
Note:
Leaving the EL-USB-3 plugged into the USB port for longer than necessary may cause some of the battery capacity
to be lost.
WARNING: Handle lithium batteries carefully, observe warnings on battery casing.
Dispose of in accordance with local regulations.
