When measuring current, turn off the circuit power before connecting

the multimeter in the circuit. Remember to place the multimeter in
series with the circuit.
When servicing the multimeter, use only the specified replacement

parts.
Use caution when working above 60 V DC, 30 V AC RMS, or 42.4 V peak.

Such voltages pose a shock hazard.
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.
