4.3 Measuring Instructions
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.
• Temporarily remove the testing leads from the device under test before operating the
function switch.
• Verify proper operation on a known source before use or taking action as a result of the
indication of the instrument.
Testing leads here include a testing leads with alligator clip (optional accessory).
4.3.1 AC Voltage Measurement (
V, mV)
1) Turn the function switch to the “
V ” or “ mV ” position.
2) Plug the testing leads into the input terminals.

4.3.2 DC Voltage Measurement ( V, mV)
1) Turn the function switch to the “
V ”or “ mV” position.
2) Plug the testing leads into the input terminals.

when measuring DCV.
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.
• If “ mV ”range is selected and the testing leads are left open-circuited, the instrument may
give a certain reading. This dose not affect your measurement.
