The ESI-385A combines many of the necessary features required for today's automotive diagnostics. For example: use the frequency readings to test crankshaft and camshaft sensors. Or, use the duty cycle setting to test feedback carburetors and idle air control motors. As you can see, it can test just about any electrical signal on the vehicle.

This is a high impedance meter (10 Meg/Ohm) that will not overload sensitive onboard
computers and sensors. The ESI-385A has 25 test ranges and measures volts, amps, ohms, RPM, duty cycle, frequency, dwell, continuity, and diode test. It comes equipped with an RPM clamp, probe test leads, alligator clip test leads, protective holster, instructions and installed 9 volt battery.
