The EEDM504F Basic Digital Multimeter TRMS is the third in Snap-on's next generation horizontal multimeter series. 
The new larger display reads easily with a quick backlight adjustment feature making it the best meter Snap-on has innovated for bright daylight use.
The EEDM504F taps into a wide range of electrical impulses necessary for diagnosing circuit or component issues. It assesses ohms, AC/DC volts, True-RMS AC, AC/DC amps, Hz frequency among other automotive electrical measurements. A record mode allows for the storage of minimum and maximum readings over a measurement period whether testing voltage or voltage drops, Ohms or resistance readings for circuits and components, or Hz for signal rates. Plus an industry leading 7-year limited warranty.
A convenient test lead storage wrap with retention strap, built-in tilt stand, and separate fuse/battery compartment for speedy replacements when needed make this multimeter an easy-to-use necessity for diesel truck techs.
