- Digital clamp meter measures AC leakage from 1 milliAmp to 60 amp.
- Average-sensing meter provides accurate readings when measuring linear loads, where the current or voltage has a sinusoidal waveform.
- Jaw opening measures current in a conductor up to 40mm without touching or interrupting the circuit.
- Data hold function keeps the most recent reading on the display after disconnecting from the circuit.
- Meets IEC safety standard 61010-1 and 61010-2-032, and is rated for CAT III installations to 600V.
The Yokogawa 30031A mini digital clamp meter is an
average-sensing, auto-ranging multimeter for measuring AC leakage
current in electrical testing applications. It has a clamp that
measures AC current leakage to 60 amp. The clamp has two jaws
that can close around an electrical conductor up to 40mm in
diameter to measure current without touching or interrupting the
circuit. To check the insulation of low-voltage circuits and
electrical components, it can measure leakage currents of 1
milliAmp. 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
meter has a 3,200-count LCD that shows readings numerically and
in a 32-segment bar graph. The unit operates on a single 3V
battery, 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. Clamp meters are
typically used by electrical engineers to measure properties of
electrical current without physically touching or disconnecting
the conductor.
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. It is auto-ranging, so it
automatically selects the appropriate operating range for the
property being measured. Accuracy and resolution specifications

vary according to the range being measured. It meets
International Electrotechnical Commission (IEC) safety standards
61010-1 and 61010-2-032, and it is rated for CAT III
installations 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. The European Conformity
(CE) marking indicates compliance with applicable European Union
directives. The unit comes with a battery, carrying case, and
instructions.

Clamp meters, also called clamp-on meters, 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. A current clamp has two
jaws that fit around a conductor to take measurements. 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 voltages. 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.
Yokogawa manufactures test and measurement equipment, navigation
systems, and industrial control systems. The company, founded in
1915 in Tokyo, Japan, has U.S. headquarters in Sugar Land, TX. It
meets International Organization for Standardization (ISO)
standard 9001:2008.
