- Digital clamp meter measures AC and DC current to 300 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 24mm 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 standards EN61010-1 and EN61010-2-032, and is rated for CAT III installations to 300V.
The Yokogawa CL220 digital clamp meter is an average-sensing,
auto-ranging multimeter for measuring current in electrical
testing applications. It has a clamp that measures AC and DC
current to 300 amp. The clamp has two jaws that can close around
an electrical conductor up to 24mm in diameter to measure current
without touching or interrupting the circuit. 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
4,000-count LCD that shows readings numerically. The unit
operates on two 1.5V batteries, and turns off automatically after
5 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 300V, 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. The unit comes with two batteries, 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.
