345 Users Manual This measuring function shows the voltages and currents in oscilloscope form, as well as their instantaneous values at the cursor position. This function clearly represents current and voltage waveforms and any distortion present. On entry to Waveforms mode, the time base is set to 5 ms/div. The symbol B is shown next to this setting to indicate that a 2 sec press of the HOLD/RUN button will change the setting. So long as a plus sign is shown, the sweep speed can be increased. The minus sign is shown at 2.5 ms/div, when at the maximum speed. The dual scale display screen shows the measured waveforms on separate grids with appropriate scales as in the display below. eln30.bmp The frequency and phase difference are displayed above the waveforms. The available time base values are 50, 25, 10, 5, and 2.5 ms/division. Note If a short press of H is made, the instrument enters the HOLD mode, and H must be pressed again to return to RUN mode before the time base can be changed. 46

This measuring function shows the voltages and currents in
oscilloscope
form
,
as well as their instantaneous values at the cursor position. This function
clearly represents current and voltage waveforms and any distortion present.
On entry to Waveforms mode, the time base is set to 5 ms/div. The symbol
B
is shown next to this setting to indicate that a 2 sec press of the HOLD/RUN
button will change the setting. So long as a plus sign is shown, the sweep
speed can be increased. The minus sign is shown at 2.5 ms/div, when at the
maximum speed.
The dual scale display screen shows the measured waveforms on separate grids
with appropriate scales as in the display below.
eln30.bmp
The frequency and phase difference are displayed above the waveforms.
The available time base values are 50, 25, 10, 5, and 2.5 ms/division.
Note
If a short press of
H
is made, the instrument enters the HOLD
mode, and
H
must be pressed again to return to
RUN mode before
the time base can be changed.
