(for Frequency only)

2. Measuring Frequency by using ac Voltage function

Step 1: Turn the rotary switch to 

  position.

Step 2: Connect test leads to the circuit. Connect the common (COM) test 
lead to the circuit before connecting the live lead (connecting diagram 
refer to “Measuring AC Voltage”).
Primary display shows ac Voltage measurement reading. 
Secondary display shows Frequency measurement reading.
