Data Sheet
AU92
Automotive Multimeter
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.
n Performs all standard electrical
test for on-car and bench
troubleshooting
n Tests engine RPM and dwell
