The Different Types of Multimeters and Their Applications
The multimeter is a popular measurement instrument among electrical engineers and technicians in Singapore. This device is available under a variety of brand names, including Fluke multimeters, and is used for detecting and resolving various issues in circuits. Multimeters, which can measure electrical properties such as current, voltage, and resistance, are vital in any engineering workshop or laboratory. They have different reading capabilities depending on the model and are used by a variety of professionals, from electricians working on circuits and power sources to technicians in laboratories.
Having the right type of multimeter is the key to a task well done. Therefore, let’s learn more about the various types of multimeters to better understand their applications in the industry.
Analog Multimeters
The analog multimeter is constructed with a moving coil meter and a pointer that indicates the scale readings. Due to their internal structure, they are exceedingly sensitive and must be handled with care.
The microammeter inside the analog multimeter detects the current and moves the needle on the indicator against a graduated scale. Compared to digital multimeters, they can still detect voltage with great sensitivity due to their low resistance in current measurement.
Digital Multimeters
Equipped with a digital counter and an LCD display, the digital multimeter has become a popular electrical measuring instrument in Singapore due to its ease of reading and high measurement accuracy. As one of the most commonly utilized testing equipment in diverse industries, it enhances the accuracy of the readings by obtaining multiple signal samples within a short span of time. The device eliminates the need to physically select the measurement through its automatic ranging feature.
Digital multimeters can be classified into three distinct types:
1. Fluke Multimeters
Fluke multimeters are one of the most commonly used instruments and are configured with a number of collaborative features. Featuring a wide display, they can measure both electrical resistance and voltage. Some Fluke multimeters have advanced functions to measure frequency, temperature, humidity, and other variables, making it easy to assess different functions for each project. These devices are shielded against transient voltage. They are generally used for calibration purposes, such as calibrating current, voltage, and other electrical units.
The Fluke multimeter is small, portable, and comes with multiple selectors, so you can conveniently pick the required function. The signal’s magnitude does not need to be known or estimated for an accurate reading, as it shifts to the correct port for the required measurement. It is protected to prevent damage in case the fuse is connected to the wrong port. This instrument is typically used when working with HVAC (Heating, Ventilation, and Air Conditioning) systems and automobile batteries. Fluke multimeters are a great instrument to start with if you are unclear about the type of digital multimeter you need to use.
2. Clamp Digital Multimeters
As opposed to the Fluke multimeter, a clamp digital multimeter can test the basic electricity flow in your battery, machine, or HVAC equipment. This multimeter gets its name from the device’s clamp, which can be fastened to the area of the equipment that you wish to measure.
When using the instrument to precisely calculate the level of current, connect its clamp to the electric device. Clamp digital multimeters also include two probes for measuring voltages on electric devices. Once they are accurately measured, both can be calibrated or adjusted based on the parameters you select. With a variety of applications, it is often recommended as an excellent multimeter for professional use.
3. Autoranging Multimeter
The autoranging multimeter is a simple device that measures the readings you need to take automatically. As it has fewer knobs and settings to work with, it usually measures only one component at a time. This tool is ideal for simple projects and is highly recommended for both beginners and professionals.
