Amprobe® True RMS Auto-Ranging Digital Multimeter with Temperature & Backlit Display

Description

The Amprobe® 34XR-A is a true rms digital multimeter with temperature measurement. The 34XR-A includes all the features and functions needed for a wide range of applications. True-rms instruments are accurate on any AC waveform.

There are two basic AC measuring systems. One is "average sensing rms indicating." this is the most common system because it is affordable and easy to manufacture. An instrument with this type of measuring system measures the average of a sine wave and then multiplies it by 1.112 allowing the instrument to indicate rms.

This measuring system is only accurate on sine waves.

The second measuring method is called "rms sensing rms indicating." an instrument with this type of measuring system computes the rms value of the measured waveform (sine or otherwise). This is referred to as "true-rms" reading. This measuring system is accurate for any waveform.

When an average sensing instrument is used on a non-sinusoidal waveform measurement accuracy could be off as much as 50%. Since you may not know what type of AC waveform you are measuring a true-rms instrument should be used whenever possible.
