- Manual and auto ranging digital insulation multi meter measures insulation resistance, current, voltage, and resistance for testing line insulation on motors, generators, cables, and switch gear.
- True RMS meter provides accurate readings when measuring linear or nonlinear loads where the current or voltage has an undistorted or distorted waveform.
- Insulation test voltages of 550V and 1000V and insulation measurement range of 0.1 to 600 megaohms.
- Live circuit detection prevents insulation test when voltages over 30V are detected.
- Safety ratings include Ingress Protection certified IP40; European Conformity (CE) marking; UL 61010 1; ANSI/ISA S82.01 2004; CAN/CSA C22.2 No. 1010.1:2004; IEC safety standards 61010 1:1002 and 61010.1 04, IEC61557 1; IEC61557 2; and IEC/EN 61010 1, 2nd edition for Category III installations up to 1000V and Category IV installations up to 600V, and Degree 2.
The Fluke 1577 digital insulation multimeter (also known as a
multitester) is a true RMS, auto- and manual-ranging meter that
measures current, voltage, and resistance for testing line
insulation on motors, generators, cables, and switch gear. The
insulation test voltages of 500 and 1000V measure resistance from
0.1 to 600 megaohms. Live circuit detection increases user safety
by preventing insulation tests when voltages exceed 30V, and
auto-discharge of capacitive voltage increases user protection.
An audible continuity sensor confirms a circuit conducts
electricity. The LCD is backlit for readability in low light. A
hold function freezes the reading on the display. An alarm sounds
when the test leads are connected to the wrong jack for the
measurement being taken. The unit automatically turns off after
20 minutes of nonuse to conserve battery life or can be disabled
for extended readings, and a low-battery indicator signals when
the meter's batteries need to be replaced. The meter included a
set of detachable test leads, a remote probe, alligator clips, a
hard case, and instructions.
This true RMS (root mean square) meter provides accurate
readings when measuring linear loads, such as standard induction
motors and incandescent lights, where the current or voltage has
an undistorted waveform, or nonlinear loads, such as electronic
devices or motors, where the current or voltage has a distorted
waveform. When turned on, the meter is in auto-ranging mode and
automatically selects the correct operating range for the
property being measured. It can be switched to manual-ranging
mode, which allows the operator to choose the appropriate
operating range. The display has a 6,000-count resolution,
meaning it can display up to 5,999 units (3-3/4 digits) before
the operating range needs to be changed. It meets International
Electrotechnical Commission (IEC) safety standard 61010 and is
certified Category III installations up to 1000V, which covers
items used with enclosed building circuit installations (such as
service panel parts, branch circuits, and fixed installations
that are connected directly to a building's AC power supply),
Category IV installations up to 600V, which covers equipment at
the origin of the installation (such as electricity meters and
primary over-current protection equipment), and Degree
2 for indoor use.

Multimeters are electrical test meters that measure multiple
properties of an electrical circuit, such as current, voltage,
resistance, capacitance, and continuity. Available in handheld or
benchtop models, multimeters diagnose electrical problems in
electrical equipment, wiring, and power supplies. A variety of
probes, clamps, and leads can be used to connect the meter to a
circuit or device. Multimeters display information either in
analog or digital form. Factors that influence meter choice
include the electrical properties to be measured, the anticipated
range of results, and the desired level of protection against
transient voltage. Safety ratings are based on International
Electrotechnical Commission (IEC) standards for low-voltage test
equipment. IEC 61010 delineates four overvoltage installation
categories. In general, a meter with a category IV rating will
provide more protection against transient voltages than a meter
with a lower category rating.
