• Turn off circuit power and discharge all high-voltage capacitors in the circuit before you
perform resistance and capacitance measurements or continuity and diodes tests.
• Use the correct terminals, function, and range for your measurements.
• Never measure voltage when current measurement is selected.
• Use only the recommended rechargeable battery. Ensure proper insertion of battery in
the multimeter, and follow the correct polarity.
• Disconnect test leads from all the terminals during battery charging.
