Product Description
-------------------
The Amprobe AM-220 digital multimeter is an average-sensing,
auto- or manual-ranging meter for measuring current, voltage,
resistance, capacitance, frequency, microcurrent, and duty cycles
in electrical testing applications. The meter comes with a set of
detachable test leads that measure alternating current (AC) and
direct current (DC) to 10 amp, AC voltage and DC voltage to 600
volts (V), resistance to 40 megaohms, capacitance to 4,000
microfarads, frequency to 10 megahertz (MHz), AC and DC
microcurrent to 4,000 amp, and duty cycles to 99%. The microamp
reading identifies current changes in flame detector
applications. The 4,000 microfarad capacitance rating is for
testing run/start capacitors on motors. The maximum or minimum
reading mode displays the highest or lowest reading in a session
to track a sudden increase or decrease in readings. The relative
zero mode stores a reading in memory to use as a zero point for
subsequent readings, allowing for quick comparison of readings.
The hold function keeps a reading on the display, even after the
meter is disconnected. The backlit liquid crystal display (LCD)
is visible in low light. An audible continuity sensor confirms
that the circuit conducts electricity, and a diode test detects
whether the circuit's diodes work properly. An auto power-off
mode turns off the unit after 10 minutes of non-use to conserve
battery life, and a low-battery indicator signals when the
meter's batteries need to be replaced. The back of the meter has
a tilt stand that allows the meter to be propped on a surface for
hands-free use.
This average sensing, or average responding, meter provides
accurate readings when measuring linear loads, such as standard
induction motors and incandescent lights, where the current or
voltage has a sinusoidal waveform. Two ranging modes (auto or
manual) offer a range of operator control when taking readings.
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 meter has a 4,000-count (3-3/4 digit) liquid
crystal display (LCD) that can display up to 3,999 units before
the operating range needs to be changed. It meets International
Electrotechnical Commission (IEC) safety standard 61010 and is
certified for category III installations up to 600V (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).

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 voltages. Safety ratings are based on the International
Electrotechnical Commission's (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.
Amprobe manufactures electrical testing equipment for commercial,
industrial, and home use. The company was founded in 1948 and is
headquartered in Everett, WA.

From the Manufacturer
---------------------
Amprobe began life in Long Island, NY in the late 1940's under
the name Pyramid Instrument Company. In 1960 the company name was
formally changed to Amprobe Instrument Corporation. Amprobe
continued to design, engineer, manufacture and distribute product
from its Lynbrook, NY location until it was merged to form ATP
and relocated to South Florida in late 1999. The Amprobe AM-220
Red & Gray LCD Digital Multimeter measures AC/DC voltage up to
600V, AC/DC current up to 10A, resistance, capacitance, frequency
and duty cycle. AC/DC Voltage: 400mV 4.000/40.00/400.0/600 V.
