Setup and Use

The procedure for setting up the OWL Electric Current Data Logger is as follows:
1. Plug the current probe into the receptacle on the logger.
2. Adjust the range switch on the current probe to suit the application. A good way to verify a
conductor's maximum range is to check the circuit breaker or fuse rating. Then set the range on the
probe to the next highest. To maximize the resolution of the readings, always choose the lowest
range possible that will encompass the full range of data you want to record.
3. Run TrendReader Software and communicate with the logger by double clicking on the com port
icon and pointing the flashing wand at the logger's optical port. Once the Status menu is displayed
select the Setup option.
4. Make sure the equation number matches the probe being used - Refer to Table 3-2. Then select
the range corresponding to the logger's switch setting. Note the software shows the highest
possible reading which allows for a small amount of overshoot. Therefore, if the switch setting is 5
on an A60FL/A65FL then choose the 5.438 A range in software.
5. To start the logging session point the wand at the logger's optical sensor,then select Send Setup.
WARNING: DO NOT CHANGE RANGE SWITCH WITHOUT ALSO SETTING LOGGER
