To avoid damage to instrument or equipment
• Before starting measurement, make sure that the position of function switch and the
input terminals for connecting the test leads are appropriate for the desired mode of
measurement.
• Themaximuminputcurrent(limitedbyfuses)ofthe“µA”and“mA”rangesis440mA.
Be sure not to exceed the limit in the 500 mA range.
Be careful not to burn yourself
• When measuring more than 6A under exceeding40

1) Turn the function switch to the “µA” , “mA” or “A” position.
(If the magnitude of the current being measured is not known,
select the “A” position. Make sure the current being measured
is no more than 440mA before the “µA” or “mA” position is
selected.)

Plug the black test lead into the “ COM ” input terminal and the
red test lead into the “A” input terminal.
If the current is in the order of mA or less, plug the red test lead
intothe“µA•mA”inputterminal.
