Automatic AC clamp meter with two unique features: AutoTect™ and Automatic Backlight. The AutoTect™ feature senses what type of measurement is being made across the test leads. The automatic bright blue backlight has a sensor that recognises when the ambient light becomes to dim and turns itself on.

The AC71B is a complete multimeter, measuring AC and DC volts, resistance, continuity in addition to the AC current. A useful tool for the electrician, plant maintenance, HVAC or field service technician.
