• Use extreme caution when working around bare conductors or bus bars. Contact
with the conductor could result in electric shock.
• 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.
• When measuring, keep fingers behind the Tactile Barrier. See Figure 2.
• Disconnect circuit power and discharge all high-voltage capacitors before you
do diode tests or measure resistance, continuity, or capacitance.
• Do not measure ac/dc current in circuits carrying more than 1000 V or 1000 A
with the Meter Jaw.
• Never operate the Meter with the back cover removed or the case open.
• Do not measure ac current in circuits carrying more than 1000 V or 2500 A with
the Flexible Current Probe.
• Do not apply the Flexible Current Probe around or remove from HAZARDOUS
LIVE conductors.
• Take special care during fitting and removal of the Flexible Current Probe. De-
energize the installation under test or wear suitable protective clothing.
WCaution
To avoid possible damage to the Meter or to equipment under test:
• Use the proper jacks, function, and range for the measurement application.
