Performing Voltage Measurements

Ensure that the terminal connections are connected correctly before making any
measurement. To avoid damaging the multimeter, do not exceed the rated input limit.
Measuring AC Voltage
• Five ranges:
• Measurement method:
• Crest factor:
• Input impedance:
• Input protection:
1 Press .
2 Connect the red and black test leads to the respective input terminals as
shown in Figure 2-
3 Probe the test points and read the display.
In autoranging mode, the multimeter automatically selects the appropriate
range and the measurement is displayed.
