Making Measurements
The reading area displays the numeric readings of the chosen measurements on the waveform that is applied to the input jack.
∙First connect the red shielded test lead from input A, and the gray shielded test lead from input B to the signals to be measured. Connect the short ground leads to the same ground potential. (See Figure 
Note
For Ohm (Ω), continuity, diode, and capacitance measurements, use the red shielded test lead from input A and the black unshielded ground lead from COM (common). (See Figure 
To choose a frequency measurement for Input A, do the following:

 Select Hz.
Observe that Hz is now the main reading. The former main reading has now moved to the smaller secondary reading position. (See Figure
