Electrical testing and measuring tools are essential to measure or compare electrical quantities because they can compare unknown quantities with a standard value.
Electrical measuring instruments include ammeters, voltmeters, multimeters, Clamp meters, and so on. Generally, these devices measure the value of electrical quantities for instance current, voltage, resistance, and electric power.
Measurement is a necessary operation to identify the electrical measuring unit. So, It works by comparing the unit of an unknown quantity to the standard unit of electrical equipment.
Firstly, Digital Multimeter is working like an ammeter, voltmeter, and ohmmeter. It measures current, voltage, and resistance, respectively. Therefore, it is also known as an AVO meter.
Secondly, This device's primary role is to measure the electrical characteristics of tools and wires in industries. Multimeters are used for various functions depending on the requirements, such as electricity, labs, power sources, and circuits.
Finally, it is a portable gadget featuring positive and negative indication needles on a numeric LCD digital display. Batteries, home wiring, electric motors, and power sources may all be tested with multimeters.
The essential parts of the Digital Multimeter are:
- Power Source
Functions of Digital Multimeters
Depending on the type, these devices can provide a variety of readings. So, fundamental sorts of multimeters are mainly used to measure current, resistance, voltage, verify continuity, and test a whole circuit. Functions of a multimeter are:
- Firstly, It can measure Resistance in Ohms
- Capacity in Farads
- Can measure the temperature in Fahrenheit/ Celsius
- AC Voltage & Amperage
- Inductance Henry
- DC Voltage & Amperage
- Frequency in Hz
- Conductance in Siemens
- Finally, can calculate Duty Cycle
Advantages of using AVO Meter
- It gives an automatic o/p display.
- Results can record and store in memory
- It includes auto polarity functions
- It ensures accuracy
- Measuring ranges can be set automatically
- Resistance toward mechanical damage
- It has Multifunctionality
- Zero adjustments cannot be required
- In short, Measurement accuracy is high
The fluke digital multimeter may be outfit with a variety of features. In general, it has a big display and is used to monitor voltage and electrical resistance.
Moreover, some devices include advanced functions for measuring humidity, duty cycle, pressure, frequency, and temperature. Most importantly, Fluke multimeters are shielded against transient voltage. It is a tiny portable device for measuring voltage, current, and testing diodes.

The Clamp meter consisted of a basic digital multimeter and a current sensor. Likewise, it is also known as loop tester, long tester, or milliampere Clamp meter. Probes measure the voltage on the other hand clamps measure current. In short, the main advantage of using a Clamp meter is that without disconnecting the circuit someone can measure current using a clamp meter. Clamp meters are used not only for industrial equipment but also for HVAC.
They are primarily used for
Three types of clamp meters exist:
|Current transformer clamp meters||Alternating Current|
|Flexible clamp meters||Measure ac only; good for measuring in tight spaces.|
|Hall Effect clamp meters||Both AC and DC|

An electrical tester is a tool that is inserted into an electrical socket to ensure that it is properly wired.
There are different kinds of testers available in Bangladesh. But Fluke's and voltage monitors are appropriately used in a wide range of applications and circumstances. These testers are reliable, safe, and easy to use, extending from non-contact voltage monitors.
