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 1-7.)

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 1-7.)

To choose a frequency measurement for Input A, do the

following:

 Open the INPUT A menu.

Figure 1-7. Measurement Setup

 Highlight Hz.

 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 1-8.)
