4.3.10CurrentMeasurement(µA/mA/A)
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 testing 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

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)Plugtheblacktestingleadintothe“COM”inputterminaland
the red testing lead into the “A ”input terminal.
If the current is in the order of mA or less, plug the red testing
leadintothe“µA•mA”inputterminal.
4) Connect the testing leads to the circuit under test and then read
the value when it stabilizes.

Note
• Thisinstrumenthasafunctionwhichautomaticallycorrectstheoffsetoftheinternalcircuit
when measuring DCA.
This correction is designed to operate once at the following timing: power on, a function is
switched or a range is switched.
When the environment temperature is changing a certain amount, it is recommended to
switch a function and make a correction deliberately for better accurate measurement.
