General Information
The meter is a multi-function instrument with high measurement accuracy,
fast response, and high safety level. Embedded with a special IC up to
2000 counts, this IC is composed of high-precision A/D converter with
high-speed digital processor. It is with accurate measurement, high
resolution, fast operation, complete software calibration, no change in
long-term use in accuracy, which is suitable for professional engineers,
maintenance engineers, teaching, etc.
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 DC60V or AC30V (valid value),
the operator shall be careful enough to avoid electric shock.
