2. TESTING & MEASURING INSTRUMENTS
 Digital Multimeters
 Digital Clamp meters
 Leakage Current Testers
 Micro Ohmmeters
 LCR Meters

3. 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.

4. DIGITAL
CLAMPMETERS
 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

5. LEAKAGE CURRENT TESTER AND CLAMP-ON EARTH
 3-1/2 Digit ( 1999 Counts) LCD Display
 Auto Power Off Function (after 5 min)
 Low Battery Warning Indication
 Capable of Measuring Earth Voltage (0 - 20 V AC)
 Small, Light Weight & Portable
 Extremely Simple to Operate Connect - Press - Read
 Designed to Reject High Levels of Noise & Interference
 Designed to Generally Confirm to IS10656 -1983
 Range Selection & Single Person Push Button Operation
Switches

6. 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).

7. 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.
