OWON HDS Series Handheld DSO & DMM 6-Using the Scope
6.7 Input Connections
See figure 2.
Look at the bottom and the right of the Oscilloscope. The Oscilloscope has seven signal inputs:
two safety BNC jack inputs (CH1 and CH2) for scope measurements, three safety 4-mm banana
jack inputs for Multimeter R, V and A measurements, and two quadratic jack inputs for
Multimeter capacitance measurements.
Isolated input allows independent floating measurements between Multimeters and Scopes.
6.8 Displaying an Unknown Signal with Auto Set
The Auto-Set feature lets the Oscilloscope display and measure unknown signals automatically.
This function optimizes the position, range, time base, triggering and assures a stable display of
virtually any waveform. . This feature is especially useful for quickly checking several signals.
To enable the Auto-Set feature, do the following:
1. Connect the test probe to the tested signals.
2. Press the AUTO SET key and the Oscilloscope is under the automatic measurement
condition. The tested signals appear on the screen.
6.9 Automatic Zero-returning of Trigger Horizontal Position
and Trigger Level Position
When we adjust the trigger horizontal position and trigger level position to be maximal to make it
off the screen center remotely, then we perform the following steps to make trigger horizontal
position and trigger level position return to zero automatically.
1. Press OSC ◄ key and OSC ► key simultaneously, the trigger horizontal position
automatically returns to zero.
2. Press OSC ▲key and OSC ▼key simultaneously, the trigger level position automatically
returns to zero.
6.10 Automatic Measurements
The Oscilloscope offers 20 types of automatic scope measurements. Your can display two numeric
readings: measurement 1 and measurement 2. These readings are selectable independently, and
the measurements can be done on the input CH1 or input CH2 waveform.
To choose a frequency for CHI1, do the following:
1. Press MENU key and the function menu appears on the right side of the screen.
