Safety Information
The AC71 is EN61010-1 certified for Installation Category II (1000 V). It
is recommended for use with local level power distribution, appliances,
portable equipment, etc, where only smaller transient overvoltages may
occur, and not for primary supply lines, overhead lines and cable
systems.
The AC71 is EN61010-1 certified for Installation Category III (600 V). It
is recommended for use in distribution level and fixed installations, as
well as lesser installations, and not for primary supply lines, overhead
lines and cable systems.
To ensure safe operation and usage of the meter, follow these
instructions. Failure to observe warnings can result in severe injury or
death.
Do not use the meter if it is damaged. Before you use the meter,
inspect the case. Look for cracks or missing plastic. Pay particular
attention to the insulation surrounding the connectors.
Inspect the test leads for damaged insulation or exposed metal.
Check the test leads for continuity.
Replace damaged test leads before you use the meter.
If this product is used in a manner not specified by the
manufacturer, the protection provided by the equipment may be
impaired.
Do not use the meter if it operates abnormally. Protection may be
impaired. When in doubt, have the meter serviced.
Do not operate the meter around explosive gas, vapor, or dust.
Before use, verify the meter’s operation by measuring a known
voltage.
Use caution when working above 30 V ac rms, 42 V peak, or 60 V
dc. Such voltages pose a shock hazard.
When using the probes, keep your fingers behind the finger guards
on the probes.
Connect the common test lead before you connect the live test lead.
When you disconnect test leads, disconnect the live test lead first.
Remove test leads from the meter before you open the battery door.
Do not operate the meter with the battery door removed or
loosened.
To avoid false readings, which could lead to possible electric shock
or personal injury, replace the batteries as soon as the low battery
indicator (N) appears.
Do not apply more than 600 V rms between the meter terminal and
earth ground.

Introduction
The AC71 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.
The AC71 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 AC71 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 impedance.

Measurement Functions
AC and DC Volts See Figure -5-
Resistance See Figure -6-
Continuity See Figure –7-
AC Current See Figure –8-
Additional Features
Auto Power Off See Figures -2- and –3-
The meter will automatically shut itself off after approximately 30
minutes after power is turned on, or no activity has occurred with the
meter. The meter will beep when it turns off. Press the ON/OFF button
to reactivate the meter.
5
Auto Backlight See Figure -4-
The backlight illuminates the entire display for easy measurement
viewing in dark work environments. The backlight activates
automatically in low ambient light conditions.
HOLD Measurements See Figure -9-
The HOLD button allows the meter to capture and continuously display
a measurement reading. When the reading has stabilized, press the
HOLD button. The measurement value will be captured on the display.
Press the HOLD button again to release the value.
XWWARNING
Hazardous voltages present at test leads may not be
displayed when in HOLD mode.
Product Maintenance
Maintenance
Do not attempt to repair this meter. It contains no user serviceable
parts. Repair or servicing should only be performed by qualified
personnel.
Cleaning
To clean the meter, periodically wipe the case with a soft moistened
cloth. To avoid damage to the plastic components do not use benzene,
alcohol, acetone, ether, paint thinner, lacquer thinner, ketone, or other
solvents to clean the meter.
Troubleshooting
If the meter appears to operate improperly, check the following items
first.
1. Review the operating instructions to ensure the meter is being used
properly.
2. Make sure the battery is in good condition. The low battery symbol
N appears when the battery falls below the level where accuracy is
guaranteed. Replace a low battery immediately.
Battery Replacement
To replace the battery See Figure -10-
1. Turn the meter off and remove attached test leads.
2. Loosen the screw and remove the battery door.
3. Replace the battery using an alkaline 9 V battery. See General
Specifications for detailed battery specifications.
4. Replace the battery cover and tighten the screw. Recycle the battery
using approved methods.
XWWARNING
To avoid electrical, shock remove the test leads from
both the meter and the test circuit before accessing the
battery.
