The channel configuration is software selectable. Any channel can be configured to measure voltage, current or temperature. The logger is waterproof and meets the rugged IP67 (NEMA 6) standard for mounting as an engine component or on the vehicle frame.

Its small size means it is easy to install for in-vehicle testing and other field testing applications. The ADAQ Mini Logger works well for a wide range of applications including performance, monitoring, R&D, and duty cycle measurements. Its standard on-board storage is a 4GB MicroSD card. Maximum card size is 32 GB.

The ADAQ Mini Logger is also an optional companion product to the OBD and J1939 Mini Loggers. Together the ADAQ Mini Logger and either the DAWN OBD or J1939 Mini Logger simultaneously acquire analog and in-vehicle network data.

There is one 20 pin connector for the analog inputs. One connector is for power/start trigger and the third is a USB connector. The WiFi antenna connector is an option.
