Digital Multimeters
A digital multimeter (DMM) is a test tool used to measure two or more electrical values—principally voltage (volts), current (amps) and resistance (ohms).
The face of a digital multimeter typically includes four components:
Display: Where measurement readouts can be viewed.
Buttons: For selecting various functions; the options vary by model.
Dial (or rotary switch): For selecting primary measurement values (volts, amps, ohms).
Input jacks: Where test leads are inserted.
An electrical meter with integral AC current clamp is known as a clamp meter, clamp-on ammeter or tong tester.
It’s a electrical device having two jaws which open to allow clamping around an electrical conductor.
This allows properties of the electric current in the conductor to be measured, without having to make physical contact with it, or to disconnect it for insertion through the probe

Micro Ohmmeters
An ohmmeter is an electrical instruments that measures electrical resistance the opposition to an electric current.
Micro-ohmmeters make low resistance measurements.
The unit of measurement for resistance is ohms (Ω).
LCR METER
An LCR meter is a type of electronic test equipment used to measure the inductance (L), capacitance (C), and resistance (R) of an electronic component.
Data collection and Automation is made easy with a wide variety of interfaces such as; USB, USB Host Port, RS-232 and GPIB interfaces, which are available on all of LCR meters.
LCR meter must have the flexibility to measure multiple impedance parameters over a wide range of frequencies and voltages.
