The Key Off Logger (KOL) is a self-powered current logging device designed to monitor and record electrical current consumption over extended periods. The system is capable of measuring current levels ranging from milliamps (mA) to more than 500 amps (A) and can record data continuously for up to 24 hours.

Logged data is stored locally on a microSD card for convenient retrieval and analysis. The KOL features adjustable sampling rates to accommodate various testing requirements and incorporates an integrated real-time clock (RTC) to provide accurate timestamping of all recorded data.

With Bluetooth® and CAN connectivity, the KOL is well suited for vehicle electrical system analysis, key-off current draw testing, battery drain investigations, and long-duration data acquisition applications.
