AU92
Automotive Multimeter
Data Sheet
Model AU92 is a full featured multimeter that has additional
measurement for automotive servicing. It offers a built-in
thermometer to measure air, surface or immersion temperatures.
The meter also tests engine RPM and dwell in addition to standard
multimeter features of voltage, current, resistance and continuity.
Perform accurate RPM measurements for 2- and 4-stroke automotive
engines using the Inductive Pickup tool. A well designed tool
for your automotive testing needs.
