Read First: Safety Information
Understand and follow operating instructions carefully.
Use the meter, test leads and all accessories only as
specified in this manual; otherwise, the protection
provided by the meter can be impaired.
WARNING
To avoid possible electric shock, personal injury or
death, follow these guidelines:
• Do not use if meter appears damaged. Visually inspect
the meter to ensure case and jaws are not cracked.
• Inspect and replace test leads if insulation is damaged,
metal is exposed, or probes are cracked. Pay particular
attention to the insulation surrounding the connectors.
• Always ensure the meter, test leads and all accessories
meet or exceed the measurement category required
in the working environment. (i.e. CAT rating)
• Note that the measurement category and voltage
rating of combinations of the meter, the test leads,
and the accessories is the lowest of the individual
components.
• Do not use meter if it operates abnormally as
protection maybe impaired.
• Do not use during electrical storms or in wet weather.
• Do not use around explosive gas, dust, vapor,
amperage or in damp or wet environments.
• Do not apply more than the rated voltage to the meter.
• Remove the test leads from the input jacks before
measuring current.
• Replace battery as soon as battery indicator
appears to avoid false readings.
• Remove the test leads from the meter prior to
removing battery cover.
• Do not use without the battery and battery cover
properly installed.
• Do not attempt to repair this unit as it has no user-
serviceable parts.
• Use the proper terminals, functions and range for
your measurements.
• Never ground yourself when taking electrical
measurements.
• Connect the black common lead to ground or neutral
before applying the red test lead to potential voltage.
Disconnect the red test lead from the voltage first.
• Keep fingers behind the guard rings of the probe tips.
• Voltages exceeding 30VAC or 60VDC pose a shock
hazard so use caution.

CAUTION
To protect yourself, think “Safety First”:
• Comply with local and national safety codes.
• Use appropriate personal protective equipment such
as face shields, insulating gloves, insulating boots,
and/or insulating mats.
• Before each use:
- Perform a continuity test by touching the test leads
together to verify the functionality of the battery
and test leads.
- Use the 3 Point Safety Method. (1) Verify meter
operation by measuring a known voltage. (2) Apply
meter to circuit under test. (3) Return to the known
live voltage again to ensure proper operation.
• Always work with a partner.
