An electrical test tool called a clamp meter combines a conventional digital multimeter with a current sensor. Clamps are used to measure current. Voltage is measured through probes. An electrical meter with a hinged jaw allows personnel to clamp the jaws around a wire, cable, or other conductor at any point in an electrical system and measure current without disconnecting or deenergizing it.
Versatile and rugged tools for applications with high currents
Confidently take reliable readings with the True RMS, Fluke 355 digital clamp meter the tool of choice for high current clamp-on amp meter measurement up to 2000 A. The extra-wide jaw easily clamps around large conductors, typically found in high-current applications. The extra rugged design and CAT IV 600 V, CAT III 1000 V ratings add an extra element of user protection when taking high-powered measurements.
Accurate peak measurements can be taken using the in-rush current mode, ideal for motors and inductive loads. The 355 also measures voltage and resistance, making this an ideal clamp meter for utilities, electrical contractors and industrial service technicians.
Reliably handle a wide range of high-current applications with 2000 A AC + DC True RMS, 1400 A AC, and 2000 A DC
The large 58 mm (2.3 in) jaw capacity is suitable for large or multiple conductors
CAT IV 600 V, CAT III 1000 V rating for added user protection
In-rush current measurement captures ‘power-on’ surge current with accuracy and repeatability
High voltage measurement of 1000 V AC + DC True RMS, 600 V AC, and 1000 V DC allows the user to perform multiple tests with only one tool
Resistance to 400K ohms coupled with a continuity beeper provide the convenience of a multimeter in a clamp meter.
Accurately measure frequency up to 1 kHz for optimum troubleshooting
Quickly analyze readings using the MIN, MAX, and AVG functions
A large backlit display allows for easy visibility in low-lit areas
Use the display hold feature to capture readings even when the display cannot be viewed
Use the low-pass filter to smooth out noisy loads and stabilize readings

Fluke 375 FC True-RMS AC/CD Clamp Meter measures very low voltage and very high resistance
The Fluke 375 FC, part of the Fluke Connect family of wireless test tools, delivers high performance features and ease of use. It features a VFD low-pass filter for accurate motor drive measurements and wireless communications to transmit results to a smartphone via Fluke Connect
The 375 FC offers most of the features of the Fluke 376 FC including compatibility with the iFlex flexible current probe but, unlike the 376 FC, it does not include the iFlex® probe in the package. You can measure AC and DC current to 600 A and voltage up to 1000 V with the fixed jaw clamp. Or connect an optional iFlex® flexible current probe to expand your measurement range to 2500 A AC. The large diameter and flexible design of the iFlex probe make it easier to measure around large conductors in tight spaces or to access individual wires.
Wireless connectivity improves productivity
Using its Bluetooth connectivity to Apple and Android devices, you can read the 375 FC results a safe distance away on your smartphone, wearing less PPE. You can create and send reports in email right from the field and save results to the cloud. You can also converse with colleagues in real-time with ShareLive™ video calls.
