One of the most common test equipment being used today is the digital multimeter, or the DMM. This equipment is able to provide excellent readings of the basic measurements of amps, volts and ohms. These digital multimeters use digital and logic technology. The use of integrated circuits enables many new test features to be embedded. DMM’s are able to offer as standard the basic measurements that includes:
- Current (DC)
- Current (AC)
- Voltage (DC)
- Voltage (AC)
- Resistance
Most DMM’s are also able to offer additional test capabilities that include:
- Capacitance
- Temperature
- Frequency
- Transistor test
- Continuity (buzzer)
You need to look at the parameters and specifications when you choose a digital multimeter. Consider the measurements that can be made, the ranges, number of digits in the display as well as the mechanical details. The accuracy of a digital multimeter also requires careful consideration.
Digital multimeter offers several electronic measurement task in one tool. How convenient that is! Other terms for this is voltmeter or Ohm meter or Volt Ohm meter. The new improved integrated circuits of digital multimeter are more efficient, faster, and works with a large accuracy. Make sure that the digital multimeter you’ll buy has continuity and is packed with smart features, has the ability to log and graph data and also troubleshooting.
A digital multimeter has only three parts. These are the Display Screen. Selection Knob and Ports. The Display Screen is for better visualization. It has a 5-digit display screen. One for the sign value, and the other 4 for the number representation. The Selection Knob allows the user to choose the different jobs performed by the multimeter. There are actually two ports located in front of the unit. These are the maVΩ and the COM port. The maVΩ port allows the measurement of all the three units: current up to 200 mA, voltage and resistance. Red probe is plugged into this port. The COM port means common and black probe is plugged into this port. The particular 10A port is used to measure large current in the circuit.
Auto range is one of the features which is very useful and should be in a multimeter. It enables the multimeter to change its internal range according to the requirement to detect the correct voltage, current, or resistance of the circuit. It prevents overloading if the meter is in volt range. A Back-lit LCD is also very fancy and very useful especially if you are in a dark place. Auto-off is also a great feature. It tends to help those users who easily forget to turn the meter off when not in use. And using decent probes than lead is better because they make work easier and easy to replace if get damaged. Auto polarity is also an important feature because it lets you know the polarity of the current. Whether the voltage of the current being measured shows positive reading, or negative reading.
