G Safety Information
Understand and follow the operating instructions carefully.
G WARNING
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 61010-031 and shall have a
voltage RATING of at least the voltage of the circuit to be measured.
■ 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 specified in the Electrical Specifications 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 flash exists.

Making basic measurements
Preparation and Caution Before Measurement
G: Observe the rules of G Warnings and G Cautions
The figures on the following pages show how to make basic measurements.
When connecting the test leads to the DUT (Device Under Test) connect the common test
lead before connecting the live test lead. When removing the test leads, remove the live
test lead before removing the common test lead.
