10. Voltage Measurement
Do not measure circuits that may contain voltages > 600 VDC or
> 600 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!
10.1 DC VOLTAGE MEASUREMENT
1.
Connect the red test lead to the "VΩmA" jack and the black lead to the
"COM" jack.
2.
Set the rotary switch in the desired V
measured is unknown beforehand, you should set the range switch in
the highest range position and then reduce gradually until the ideal
resolution is obtained.
3. Connect the test leads to the source being measured.
4. Read the voltage value on the LCD display along with the polarity of
the red lead connection.
