• Do not attempt a current measurement when the open
voltage is above the fuse protection rating. Suspected
open voltage can be checked with voltage function.
• Never attempt a voltage measurement with the test lead
inserted into the A input terminal.
• Disconnect the test leads from the test points before
changing the position of the function rotary switch.
• Disconnect circuit power and discharge all high-voltage
capacitors before testing resistance, continuity, diodes, or
capacitance.
• Always use proper terminals, switch position, and range for
measurements.
• Do not use the LoZ mode to measure voltages in circuits
that could be damaged by this mode’s low impedance.
• Replace the fuse as soon as the indicator (FUSE) appears.
• Never connect a source of voltage with the function rotary
switch in resistance, diode, continuity, and capacitance
position.
• Never set the meter in current function to measure the
voltage of a power supply circuit in equipment that could
result in damage the meter and the equipment under test.
This identifies conditions and actions that could DAMAGE
the meter or equipment under test. To avoid possible
damage, follow below guidelines.
