1. General information
This digital multimeter is a high-quality, high-precision, safe meter. 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 60V DC or 30V AC (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 AC voltage.
Then, select DC voltage measuring range equivalent to or greater than that for
