BATTERY REPLACEMENT
We recommend that you replace the battery every 12 months, or prior to logging critical data.
The EL-USB-5 does not lose its stored readings when the battery is discharged or when the battery is replaced; however, the data logging
process will 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 lithum batteries. Check with your supplier that the battery you are ordering is ‘press t’ and is not tted with solder
tags. Before replacing the battery, remove the EL-USB-5 from the PC.
Note:
Leaving the EL-USB-5 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.

EDGE TRIGGERING
If the user selects ‘rising edge’ triggering, then an event is recorded at the point a signal goes from low to high. This is the default
setting.
If the user selects ‘falling edge’ triggering, then an event is recorded at the point a signal goes from high to low.
