The Megger MIT300 series insulation resistance tester measures
insulation resistance, voltage, and continuity in electrical
installations, building maintenance, and electrical testing. The
average-sensing meter provides accurate readings when measuring
linear loads, where the current or voltage has a sinusoidal
waveform. The dual LCD screen indicates test results either
digitally or with an analog arc function to replicate the
response of analog meters. The tester measures insulation
resistance from 0 to 1,000 megohms, voltage from 0 to 600V, and
continuity from 0.01 to 100 ohms. The unit has a test inhibit
function that prevents testing on circuits carrying over 50V. The
tester is safety rated to European Standard EN61010-1, Category
III, 600V. The unit is also Ingress Protection 54 (IP54)-rated
for protection against dust and splashing water. The unit has a
rubberized outer case for protection against bumps and short
drops. The Megger MIT300 series is commonly used by electricians
and electrical contractors.

Electrical test meters report electrical circuit properties, such
as voltage, resistance, capacitance, and continuity. Available in
handheld or benchtop form, they detect electrical problems in
equipment, wiring, and power supplies. A variety of probes,
clamps, and leads can be used to connect the meter to a circuit
or device. Single-function meters, such as battery testers and
voltage testers, measure one property of a circuit, and
multimeters measure multiple properties. Electrical test meters
display information either in analog form using a needle that
moves on a calibrated scale, or in digital form using digits or a
graphic representation on an LED screen. Meters have electrical
properties that are to be measured and the anticipated range of
results, and should have a rating that is higher than the maximum
value of the anticipated range. An electrical test meter has
multiple settings corresponding to potential ranges of values for
the properties it can measure. A manual ranging meter requires
the operator to flip through different settings until the correct
range is reached. An autoranging meter cycles through range
settings automatically until it reaches the correct range.
Megger manufactures equipment for cable fault locating,
protective relay testing, telecommunications and data integrity,
and power quality testing under multiple brand names, among them
Megger, Biddle, States, and AVO. The company, founded in 1889, is
headquartered in Dover, England, and meets International
Organization for Standardization (ISO) 9001:2008 standards.
