The safety rated Fluke T+Pro gets field-tested by non-electricians. Larger buttons for gloved hands and a battery life indicator helped to make the transition from the old solenoid-based testers to the T+Pro much easier.

A digital multimeter is essentially a voltage-measuring tool with some current abilities. A clamp meter is basically a current-measuring tool with some voltage abilities. They are distinctly different instruments, each with its own advantages.
On circuits protected by GFCIs (Ground Fault Current Interrupters), leakage current can cause unnecessary and intermittent tripping. In extreme cases, it can cause a rise in voltage on accessible conductive parts.
Early reports from the field suggest that the new Fluke 772 and 773 Milliamp Process Clamp Meters may be game changers, breaking new ground for technicians in the HVAC controls industry. With the feature sets these meters offer, troubleshooting of the most common problems in modern control systems becomes a snap.
Clamps measure current. Probes measure voltage. Having a hinged jaw integrated into an electrical meter allows technicians to clamp the jaws around a wire, cable and other conductor at any point in an electrical system, then measure current in that circuit without disconnecting/deenergizing it.
Using Fluke’s 376 True RMS Clamp Meter, a rooftop solar contractor saves time and ensures quality panel installation by testing throughout the installation process.
MacDonald-Miller standardized on the Fluke 902 Clamp Meter when it came out several years ago.
Accessory current clamps expand a multimeter's flexibility and measurement capabilities by allowing it to measure up to thousands of amps.
