
When using the test leads, keep your fingers behind the finger guards on the test
leads.

Remove the test leads from the multimeter before you open the battery cover.

To avoid false readings, which may lead to possible electric shock or personal injury,
replace the battery as soon as the low battery indicator appears and flashes.

Disconnect circuit power and discharge all high-voltage capacitors before testing
resistance, continuity, diodes, or capacitance.

Use the proper terminals, function, and range for your measurements. When the
range of the value to be measured is unknown, set the rotary switch position as the
highest range, choose the auto ranging mode. To avoid damages to the multimeter,
do not exceed the maximum limits of the input values shown in the technical
specification tables.

Connect the common test lead before you connect the live test lead. When you
disconnect the leads, disconnect the live test lead first.

Before changing functions, disconnect the test leads from the circuit under test.
