Metermann AC71 Digital multimeter
AC Clamp-on Multimeter
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.
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.
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.
offers the AutoTect feature. AutoTect checks the
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 or
Continuity 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
