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
ô Highlight Hz.
í 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.)
