Safety Information
G
Understand and follow the operating instructions carefully.
WARNING
G
Identify hazardous conditions and actions that could cause BODILY HARM or DEATH
When using test leads or probes, keep your fingers behind the finger guards.
Personal protective equipment should be used if there are ACCESSIBLE
HAZARDOUS LIVE PARTS in the installation where measurement is to be carried
out.
Remove test leads from meter before opening the battery door or meter case.
Use the meter only as specified in this manual; otherwise, the protection provided
by the meter may be impaired.
Always use the proper input terminals, switch position, and range for
measurements.
Verify the meters operation by measuring a known voltage. If in doubt, have the
meter calibrated.
Do not apply more than the rated voltage, as marked on the meter, between
terminals or between any terminal and earth.
Use caution with voltages above 30 V AC rms, 42 V AC peak, or 60 V DC. These
voltages pose a shock hazard.
To avoid false readings that can lead to electric shock and injury, replace the
battery as soon as the low battery indicator blinks.
Disconnect circuit power and discharge all high-voltage capacitors before testing
resistance, continuity, diodes, or capacitance.
Do not use the meter around explosive gas or vapour.
To reduce the risk of fire or electric shock do not expose this product to rain or
moisture.
Probe assemblies to be used for MAINS measurements shall be RATED as
appropriate for MEASUREMENT CATEGORY III or IV according to EN 61010031 and shall have a voltage RATING of at least the voltage of the circuit to be
measured.

Safety Information
G
■ DO NOT USE the test leads if the internal white insulation layer is exposed.
■ DO NOT USE the test leads above maximum ratings of CAT Environment or
voltage and current that are indicated on the probe and probe tip guard.
■ Do not apply a current with a frequency that is higher than the frequency
response range specied in the Electrical Specications section.
■ Do not apply or remove the clamp or test leads on or around uninsulated
hazardous live conductors where a potential to cause electric shock, electrical
burns or arc ash exists.
CAUTION
G
Disconnect the test leads from the test points before changing the position of the
function rotary switch.
Never connect a source of voltage with the function rotary switch in Ω,
position.
Do not expose the meter to extremes of temperature or high humidity.
