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.
• Themaximuminputcurrent(limitedbyfuses)ofthe“µA”and“mA”rangesis440mA.
Be sure not to exceed the limit in the 500 mA range.
Be careful not to burn yourself
• When measuring more than 6A under exceeding40
℃
conditions, the continuous
measuringtimeshallbewithin3minutes,thenkeepdisconnectedformorethan10
minutes.
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.)
2) Please select between DC and AC. When selecting AC, press
the SELECT key.
3)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
intothe“µA•mA”inputterminal.
4) Connect the test leads to the circuit under test and then read the
value when it stabilizes.
