The E-Meter (also electropsychometer and Hubbard Electrometer) is an electronic device used in Scientology that allegedly "registers emotional reactions". [1] After claims by L. Ron Hubbard that the procedures of auditing, which used the E-Meter, could help heal diseases, the E-Meter became the subject of litigation.

Before we dive into decoding multimeter symbols, let’s take a quick moment to review the four main parts of a multimeter. There are two types of multimeters: analog and digital. While both measure current, resistance, and voltage, digital multimeters are more commonly used today due to their increased accuracy. The four main parts of a multimeter a...
Hold Button
When you’re measuring electrical properties with your multimeter, sometimes you might need to freeze the reading to take a closer look or record it for future reference. That’s where the Hold button comes in handy. This button lets you “hold” the reading on the display, allowing you to examine the measurement at your leisure. Whether you’re troubleshooting a faulty electrical system or trying to calibrate a piece of equipment, the Hold button is an indispensable feature that can make your job...
MIN MAX Button
If you were using a higher-end multimeter, chances are it has a Min Max function. This feature is incredibly useful for monitoring readings over a certain period to detect any fluctuations or anomalies. Here’s how it works: first, you preset a maximum and minimum limit for the multimeter reading. Then, you take a steady measurement and hit the Min Max button. The multimeter will then track the minimum and maximum values within the range you’ve set. If the reading goes above or below the prese...
RANGE or LO/HI Button
This button is typically located at the top of your multimeter and has a “Lo/Hi” symbol above it. Its purpose is to help you cycle through different meter ranges to find the most appropriate one for your measurement. While many modern multimeters, like the Fluke 117, come with auto-ranging capabilities, some models still require you to manually switch between different ranges. For example, you may need to switch from measuring in ohms to megaohms. In these cases, the Range button becomes incr...
Understanding the symbols on a multimeter is crucial in using the device correctly and ensuring accurate measurements. Some of the essential symbols to know include the On/Off switch, the AC and DC voltage buttons, the Range (Lo/Hi) button, and the Function button. Knowing the Min/Max, Hold, and Auto-V LoZ buttons can help you get more out of your ...
This tutorial will show you how to use a digital multimeter (DMM), an indispensable tool that you can use to diagnose circuits, learn about other people's electronic designs, and even test a battery. Hence the 'multi'-'meter' (multiple measurement) name. The most basic things we measure are voltage and current.

Looking inside volt and ampere meters Simple explanation without complex mathematics by Jules Perrin VK3JFP Ever wondered how your trusty analogue voltmeter works? A lot goes on inside the meter, but it is all based on Ohm’s Law. Digital meters work on the same principles as analogue, but without a colourful display. Moving Coil Meter (MCM)
An E-meter is an electronic device used during Dianetics and Scientology auditing. The device is a variation of a Wheatstone bridge, which measures electrical resistance. It is formally known as the Hubbard Electrometer, for the Church's founder, L. Ron Hubbard. Critics point to a lack of scientific basis for the E-meter and associated practices.
Apr 15, 2023 · A typical multimeter can measure voltage, current, and resistance. The best multimeters can also measure other electrical characteristics such as continuity, frequency and capacitance. They also come with built-in non-contact voltage detectors.
