1. PRECAUTIONS AND SAFETY MEASURES
�
Warnings: Read Before Using
To avoid possible electric shock or personal injury:
• Use the Meter only as specified in this manual or the protection provided by the
instrument might be impaired.
• Avoid working alone so assistance can be rendered.
• Never measure ac current while the test leads are inserted into the input jacks.
• Do not use the Meter in wet or damp environments.
• Do not use the Meter if it appears damaged. Inspect the Meter before use. Look
for cracks or missing plastic. Pay particular attention to the insulation around the
connectors.
• Inspect the test leads before use. Do not use them if insulation is damaged or metal is
exposed.
• Check the test leads for continuity. Replace damaged test leads before using the Meter.
• Have the Meter serviced only by qualified service personnel.
• Use extreme caution when working around bare conductors or bus bars. Contact with
the conductor could result in electric shock.
• Do not hold the Meter anywhere beyond the tactile barrier.
• Do not apply more than the rated voltage, as marked on the Meter, between the
terminals or between any terminal and earth ground.
• Remove test leads from the Meter before opening the Meter case or battery cover.
• Never operate the Meter with the battery cover removed or the case open.
• Never remove the battery cover or open the case of the Meter without first removing
the test leads from a live conductor.
• Use caution when working with voltages above 30 V ac rms, 42 V ac peak, or 60 V dc.
These voltages pose a shock hazard.
• Do not attempt to measure any voltage that might exceed the maximum range of the
Meter.
• Use the proper terminals, function, and range for your measurements.
• Do not operate the Meter around explosive gas, vapor, or dust.
• When using probes, keep fingers behind the finger guards.
• When making electrical connections, connect the common test lead before
connecting the live test lead; when disconnecting, disconnect the live test lead before
disconnecting the common test lead.
• To avoid false readings that can lead to electrical shock and injury, replace the battery
as soon as the low battery indicator appears. Check Meter operation on a known
source before and after use.
• When servicing, use only specified user serviceable replacement parts.
• Adhere to local and national safety codes. Individual protective equipment must
be used to prevent shock and arc blast injury where hazardous live conductors are
exposed.
• Only use the test lead provided with the Meter or UL Listed Probe Assembly rated CAT
IV 600V or better.
• Do not use HOT STICK to operate the AT-7000-R Receiver around voltage more than 600V
