The AC71B is a digital clamp multimeter with two additional unique features:AutoTect™ and automatic backlight. The AutoTect™ feature automatically senses what type of measurement is being made when the test leads are placed across a measurement point. There is no knob to turn. The meter knows what is being measured and the digital display shows the measured value along with the associated unit icon. AutoTect™ also utilizes a lower input impedance. This helps determine if voltage is from leakage (called ghost voltages) or a hard connection. Any ghost voltages will be zeroed out by the lower input impedance. The automatic backlight has a sensor that recognizes when the ambient light becomes dim and turns itself on. A bright blue backlight is then available to easily read the measurement value on the digital display. 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.
