Measurement Functions
Fig 3.18 Time Sweep Setup
• To start the sweep recording, move the cursor to the GO! field
and press enter.
• The time sweep automatically stops when the defined duration
has expired. Alternatively, the sweep may be stopped manually
by pressing enter with the cursor on the REC field.
• To display the mean or the min-max values of the recorded sweep,
place the cursor to the corresponding field and select the required
mode by using the enter and the arrow keys.
• In order to analyze the sampled curve more detailed, activate the
arrow mode by placing the cursor to the corresponding symbol
and pressing the enter key. Move the readout line to the sample(s)
of interest by using the left / right keys, or press the up/down keys
to zoom out/in the X-axis.
• To zoom in/out the Y-axis, move the cursor to the zoom mode
field, press enter and
- use the up/down keys to zoom out/in the Y-axis
- use the left/right keys to scroll through the Y-axis.
The last time sweep recording will be stored internally, even after
leaving the sweep mode or switching off the Minilyzer. As soon as the
time sweep mode is re-entered, the last displayed curve will appear
on the graph, until a new time sweep recording is started.
NOTES • As soon as the sweep mode is entered, the filter
that has been active during the recording of the last
curve will be re-activated.
• If a running time sweep is stopped due to empty
batteries, the recorded data will not be lost.
• The auto power off is disabled during a time
sweep.
