Extra-High Accuracy VOM

Higher accuracy specifications for those more critical measurements are found in the Model 270-5. It has a better than 30% improvement in voltage and resistance accuracy as a full-function/range member of the Simpson 260 type VOM group.

DC V Accuracy 1.25% of Full Scale
AC V Accuracy 2% of a Full Scale
Resistance Accuracy 1.08 of Arc
Diode Protected Self-Shielded Movement
Includes Batteries and Probe Leads With Alligator Clips
