Introduction

The AC7B is a digital clamp multimeter with numerous unique

features. Two of them being AutoTect

The AutoTect

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.

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 AC7B 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.

Autotect

The AC7B offers the AutoTect

signal received across the two test lead points and automatically

determines the type of measurement to be made. It senses whether

AC Volts, DC Volts, Resistance, Continuity or Diode is across the

test nodes.

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.
