- Jaw opening measures current in a conductor up to 55mm without touching or interrupting the circuit.
- Peak hold function records the maximum measurement of a current surge.
- Meets IEC safety standards EN61010-1, EN61010-2-031, and EN61010-2-032, and is rated for CAT III installations to 600V and CAT II to 1000V.
The Yokogawa CL255 digital clamp meter is a true RMS sensing,
auto-ranging multimeter for measuring current, voltage,
resistance, and frequency in electrical testing applications. It
has a clamp that measures AC current) to 2,000 amp and DC current
to 2,000 amp. The clamp has two jaws that can close around an
electrical conductor up to 55mm in diameter to measure current
without touching or interrupting the circuit. A set of test leads
is included for measuring AC voltage to 750, DC voltage to
1,000V, resistance to 4,000 ohms, and frequency to 3,999Hz
(hertz). The peak hold function records the maximum measurement
of a current surge. 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. An audible continuity sensor confirms that the circuit
conducts electricity. The meter has a 3,999-count LCD that shows
readings numerically. It comes with an output plug to connect to
a device for DC output. The unit operates on
a single 9V 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 true RMS (root mean square) sensing meter provides accurate
readings when measuring linear or non-linear loads, regardless of
waveform. It is auto-ranging, so it automatically selects the
appropriate operating range for the property being measured.
Accuracy and resolution specifications
( https://images-na.ssl-images-.com/images/G/01/BISS/ClampMeters/YokogawaClampMeter.datasheet.pdf )
vary according to the range being measured. It meets
International Electrotechnical Commission (IEC) safety standards
EN61010-1, EN61010-2-031, and EN61010-2-032, 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, and for CAT
II to 1,000V, which covers energy-consuming equipment connected
to a fixed installation, including household, office, and
laboratory appliances. The unit comes with a battery, a test lead
set, an output plug, a 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
