Introduction

The AC7B is a digital clamp multimeter with numerous unique
features. Two of them being AutoTect
The AutoTect
TM
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
TM
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.
