Average-Sensing AC Calculation—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.

Display Count—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.

Ultra Grip—Ultra-grip drivers have a multicomponent handle that provides comfort and the best possible grip for achieving maximum torque.

Voltage Detector—Those with a voltage detector safely test for AC voltage without contacting live wires. Light and sound indicators alert you when over 50 volts AC is detected. The detector is attached to the tool’s handle; remove it from the handle to use it on its own. Bits turn eight screw sizes and the shaft two external hex sizes.

120V AC to 500 kV AC—120V AC-500kV AC detectors sense voltages as low as those in a power socket and as high as those in high-power transmission lines. Since they detect a wide range of voltages, they’re a helpful tool for rescue workers, electricians, and telecom workers. They can also connect to an app to notify emergency response services when there is a fall, injury, or no movement detected. The app is optional, and it requires a paid subscription. This safety feature makes these detectors a great option for those working alone.

2.4 kV AC to 500 kV AC—2.4kV AC to 500kV AC detectors identify a wide range of voltages found in high-power transmission lines, so they’re often used by linemen. However, they won’t detect the low voltage ranges found in telecom lines or small machinery.

True RMS AC Calculation—The true RMS meter takes 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—Display count is an industry designation and not an actual value. These 1,000-count meters show numbers up to 999.

True RMS AC Calculation—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.

Multimeters with Calibration Certificate—Multimeters with calibration certificate include a document stating that they have passed a test for accuracy.

Display Count—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.
