requirements pertaining to 600V CAT IV, 1000V CAT.
Ⅲ
and requirements on pollution degree 2.
Please read carefully this Operation Manual and pay attention to safety guidelines before operating
this meter.
1.1 Safety information
1.1.1 Safety instructions
• Before operating this meter, the operator must observe all standard safety procedures in the two
respects below:
A. Safety procedures against electric shock
B. Safety procedures against unintended use
• To ensure your personal safety, please use the test lead that accompanies the meter. Before
operating this meter, ensure that the test lead is flawless.
1.1.2 Safety considerations
• When the meter is used in the vicinity of the equipment that produces strong electromagnetic
interferences, the reading on the meter will grow unstable and even produce serious errors.
• Don't operate the meter or pen-shaped meter whose appearance is damaged.
• The safety function of the meter will become null if the meter is not properly operated.
• The meter must be operated with great care when working in the vicinity of an exposed conductor
or bus line.
• The meter is prohibited from being used in the vicinity of any explosive gas, vapor or dust.
• The measurement must be made with correct input terminals and functions and within the allowable
measuring range.
• To prevent the meter from being damaged, the value to be input shall not exceed the extremes
allowed by each measuring range.
• When the meter has already been connected to the line being measured, the operator is
prohibited from touching the input terminal that is not in service.
• When the voltage measured exceeds 60Vdc or 30Vac (valid value), the operator shall be careful
enough to avoid electric shock.
• When making measurement with a test lead, place your fingers behind its protective ring.
• When switching to another measuring range, be sure that test lead has already been taken off
the measured circuit.
• For all DC functions, to prevent potential electric shock as a result of incorrect reading, please first
use AC functions to check the absence of any AV voltage. Then, select DC voltage measuring
range equivalent to or greater than that for AC voltage.
