AM-530 Description
The Amprobe AM-530 Autoranging Digital Multimeter is the multimeter of choice for professional electrical contractors. The AM530 is a True-rms digital multimeter so it accurately measures voltage on systems affected by harmonics. With its full menu of digital multimeter features, you can use it to: measure and verify the presence of voltage before connecting new equipment or performing repairs; run new wiring; check continuity of electrical connections; identify blown fuses; troubleshoot motors or check transformers.
The CAT III 600V safety rating provides an extra measure of safety for high voltage multimeter applications. The Amprobe AM-530’s built-in flashlight helps you see wire colors in the dark and third hand probe holder gives you an extra hand when you need it.
Why you need a True-RMS Reading Multimeter
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.
