Inspection and Measuring Fixturing
Use these components in coordinate measuring machine (CMM) applications to raise a workpiece and reliably position it on a fixture plate with 1/4"-20 holes. They are not for use in machining applications.
For technical drawings and 3-D models, click on a part number.
Hold-down clamps thread directly into a fixture plate, tower, or compatible component. Slide the clamp down its shaft and press into place against the workpiece for a light hold. They're also known as tension spring clamps. Wire clamps have a slimmer profile than standard, making them good for clamping small parts or minimizing contact area for additional visibility.

Analog Clamp-On Multimeters
Measure rapidly changing electrical values more easily than with a digital multimeter. Convenient for taking frequent high current measurements, the meter has jaws that surround a cable to test current without interrupting the circuit. Use the included test leads to perform other electrical tests.
This multimeter is average sensing, so it takes accurate AC measurements when testing equipment that has a linear load and draws current in a smooth sine wave, such as standard induction motors.

Clamp-On Current Meters
Measure current without interrupting the circuit—jaws surround a cable for testing, making these meters convenient for taking frequent measurements.
These current meters are average sensing, so they take accurate AC measurements when testing equipment that has a linear load and draws current in a smooth sine wave, such as standard induction motors.
Display count is an industry designation and not an actual value. For example, a 2,000-count meter shows numbers up to 1,999. A higher display count means the meter can give a more precise measurement.

Clamp-On Multimeters
Suitable for testing high current, these multimeters have jaws that surround a cable to test without interrupting the circuit. They include test leads to perform other electrical tests.
Average sensing multimeters take accurate AC measurements when testing equipment that has a linear load and draws current in a smooth sine wave, such as standard induction motors. True RMS multimeters take accurate AC measurements regardless of the load type or sine wave shape. This is important for testing electronic devices that draw current in short pulses that can distort the shape of the wave, such as computers and adjustable-speed drives.
Display count is an industry designation and not an actual value. For example, a 6,000-count multimeter shows numbers up to 5,999. A higher display count means the multimeter can give a more precise measurement.

Fluke Wireless Remote-Reading Clamp-On Current Meters
Take current measurements from a distance with these high-quality, durable Fluke meters. They wirelessly transmit readings to a separate display. Because the jaws surround a cable, these meters are convenient for taking frequent measurements since you don't have to interrupt the circuit.
The meters work with the Fluke 3000 FC multimeter, a computer with a Fluke pc3000 FC connector plugged in (not included), or a mobile device that has the Fluke Connect app.
These true RMS multimeters take accurate AC measurements regardless of the load type or sine wave shape. This is important for testing electronic devices that draw current in short pulses that can distort the shape of the wave, such as computers and adjustable-speed drives.
