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.
