10.1 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!
1. Set the rotary switch in the desired "
2. Press "SELECT" to choose the AC or DC measurement mode.
3. Connect the red test lead to the "VHz" jack and the black lead to the
"COM" jack.
4. Connect the test leads to the source being measured.
5. Read the voltage value and the polarity of the red test lead on the LCD
display.
Notes
 In the AC range, press "Hz%" to measure the frequency or duty cycle.
