GENERAL SAFETY
Prior to using the multimeter, please read the product manual and ensure you have a solid
understanding of the multimeter’s functions and features.
WARNING
!
The warnings, cautions, and instructions discussed in this instruction
manual cannot cover all possible conditions or situations that could
occur. It must be understood by the operator that common sense and
caution are factors that cannot be built into this product, this must be
supplied by the operator.
SAFETY INSTRUCTIONS
SAFETY STANDARDS
•
CAT III 600V, CAT II 1000V, double insulation and material pollution grade II.
•
CAT safety level: Category III is suitable for measuring circuits connected to the power
distribution section of a buildings low voltage supply unit.
SAFETY INSTRUCTIONS
•
Before using the meter inspect the case. Do not use the meter if it is damaged or the case
(or part of the case) is removed. If you can identify cracks or missing parts stop using the
meter immediately.
•
Inspect the test leads for damaged insulation or exposed wires. Check test leads
continuity. Replace damaged test leads with leads that are suitable to the meter that meet
or exceed the safety requirements.
•
Comply with local and national safety codes. Use personal protective equipment
(approved rubber gloves, face protection, and flame-resistant clothes) to prevent shock
and arc blast injury where hazardous live conductors are exposed.
•
Do not apply more than the rated voltage, as marked on the meter, between the terminals
or between any terminal and grounding.
•
Limit operation to the specified measurement category, voltage, or amperage ratings.
•
Use Product-approved measurement category (CAT), voltage, and amperage rated
accessories (probes, test leads, and adapters) for all measurements.
•
Use the correct terminals, function, and range for measurements.
•
Before each use, verify meter operation by measuring a known voltage first.
•
Do not touch voltages >30 V ac rms, 42 V ac peak, or 60 V dc.
•
Do not use the meter around explosive gas, vapor, or in damp or wet environments
•
The function selector should be placed in the right position before using the unit, do
not change the range/function during measurement to avoid damage to the meter or
equipment under test.
•
When the meter is working at an effective voltage over 60V in DC or 30V rms in AC, special
care should be taken as there is danger of electric shock.
•
Do not touch the probes to a voltage source when the test leads are connected to the
current terminals.
