The Hioki 3285 digital clamp-meter is a true RMS sensing, manual-
and auto-ranging multimeter for measuring current, voltage, and
frequency in electrical testing applications. It has a clamp that
measures AC (alternating current) and DC (direct current) to
2,000A (amperes). The clamp has two jaws that can close around an
electrical conductor up to 55mm (2.17 inches) in diameter to
measure current without touching or interrupting the circuit. A
set of test leads is included for measuring AC and DC voltage to
600V, and frequency to 1,000Hz (hertz). Frequency can also be
measured with the clamp. The meter has push buttons to select the
property to measure, and a LCD that shows the reading numerically
and in a 35-segment bar graph. The display count is 3,750 for
voltage and 2,500 for current. The peak hold function captures
the highest reading of the inrush current at the startup of
motors and other inductive loads. To enable readings of rapidly
fluctuating current and voltage, the slow function reduces the
display update rate from four times per second to once every
three seconds. The record function captures the maximum, minimum,
and average readings for a property. To aid documentation of
readings and capture readings in tight spaces, the data hold
function keeps the most recent reading on the display after
disconnecting from the circuit. The unit operates on a single 9V
6F22 battery (included) or an AC adapter (Hioki 9445-02, sold
separately), and turns off automatically after 10 minutes of
non-use to conserve battery life. It has a low-battery indicator
that signals when the battery needs to be replaced.
This true RMS (root mean square) sensing meter provides accurate
readings when measuring linear or non-linear loads, regardless of
the waveform. It has two ranging modes: manual, which allows the
user to select the operating range, and auto, which automatically
selects the appropriate operating range. Accuracy and resolution

specifications vary according to the range being measured. The
meter meets IEC (International Electrotechnical Commission)
safety standard 61010-031 and is rated for CAT (category) III
installations to 600V, which covers equipment in fixed
installations, such as switches in the fixed installation and
some industrial equipment that is permanently connected to the
fixed installation. It has CE (European Conformity) marking. The
unit comes with a carrying case.

Clamp-meters, also called clamp-on meters, have two jaws that fit
around a conductor to measure electrical current without cutting
through wires, or touching or interrupting the electrical
circuit. Available in handheld or benchtop models, clamp-meters
diagnose problems in electrical equipment, wiring, and power
supplies. All clamp-meters test for current. Some come with test
leads and inputs for measuring voltage, capacitance, and
resistance. They 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.
