Operation
10.1
AC VOLTAGE MEASUREMENT
Do not measure circuits that may contain voltages > 600 V AC or DC
Use extreme caution when measuring voltages higher than 60 VDC
or 30 VAC rms.
Always place your fingers behind the protective edges of the test
probes while measuring!
1.
Connect the black test lead to the “COM” jack and the red test lead to
the input jack.
2.
Set the selection button
to the desired “
” position.
3.
Connect the test leads across the source under measurement.
