This section describes some practical operations when using dual display
feature.
Measure DC Voltage and AC Ripple on a Rectification Circuit
A single measurement for both DC voltage and AC ripple can be displayed
through both displays while testing a rectifier circuit.
1 Connect the red and black test leads to the input terminal and probe
the test points as shown in Figure 3- 1.
Figure 3-1 Connection terminal when measuring DC voltage and AC ripple
2 Press to select DC voltage measurement in primary display.
3 Press to select AC voltage measurement for secondary display.
4 Press . Use and to select autoranging or manual range
for secondary display.
NOTE
• Press to disable the secondary display.
• Press to select the suitable range if DCV+ACV ripple is above the scale of the
current range.
