4-20mA Current Loop USB Data Logger
CONNECTION
Positive measurement input

BATTERY REPLACEMENT
We recommend that you replace the battery every 12 months, or prior to logging critical data.
The EL-USB-4 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 the battery you are ordering is 'press fit' and
is not fitted with solder tags. Before replacing the battery, remove the EL-USB-4 from the PC.
Note:
Leaving the EL-USB-4 plugged into the USB port for longer than necessary will 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.
