Important Safety Information
Electric shock and fire hazard:
• Do not expose this unit to rain or moisture.
• Do not use the unit if it is wet or damaged.
• Test leads or any other accessory, when used
to make a measurement, create a System.
The System is rated for CAT III 600 V or CAT IV
300 V when using the test leads or accessories
provided with the meter. The System CAT and
voltage rating is limited by the lowest rated
component in the System when using test leads
or accessories not provided with the meter.
• Inspect the test leads or accessory before use.
They must be clean and dry, and the insulation
must be in good condition. Do not use the test
lead if the contrasting inner layer of insulation
is visible.
• Use this unit for the manufacturer's intended
purpose only, as described in this manual.
Any other use can impair the protection provided
by the unit.
Failure to observe these warnings could result in
severe injury or death.
Electric shock hazard:
• Do not apply more than the rated voltage
between any two input terminals, or between
any input terminal and earth ground.
• Keep hands and fingers below the barriers on
the test leads.
Failure to observe these warnings could result in
severe injury or death.
Electric shock hazard:
• Do not operate with the case open.
• Before opening the case, remove the test leads
from the circuit and shut off the unit.
Failure to observe these warnings could result in
severe injury or death.

charged. Voltage must not be present.
Failure to observe these warnings could result in
severe injury or death.
Electric shock hazard:
• Do not attempt to repair this unit. It contains no
user-serviceable parts.
• Do not expose the unit to extremes in temperature
or high humidity. Refer to "Specifications."
Failure to observe these precautions may result in
injury and can damage the unit.
Electric shock and fire hazard:
• Do not connect the unit to 500V or greater for
longer than 10 minutes.
• If the unit has been connected to 500V or greater
for 10 minutes, disconnect the unit for at least 10
minutes before using again.
Failure to observe these warnings could result in
severe injury or death.
