VOLTAGE MEASUREMENT
Do not measure circuits that may contain voltages > 500 VDC or
> 500 VAC
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.
Set the rotary switch in the desired “V=” or “V~” position.
2.
Connect the red test lead to the “V
mA” jack and the black lead to the
“COM” jack.
3.
Connect the test leads to the source being measured.
