In digital mode, the 10 ms/div to 0.5 s/div
TIME/DIV
ranges
can be expanded by a factor of 100 by depressing the
SLOW
X100
switch. For example, the 10 ms/div setting becomes 1000
ms (1 sec)/div when this switch is engaged. This time base
expansion is extremely useful for observing very slow events.
With it, the scope is capable of recording an event up to 500
seconds in duration (.5 sec/div x100 becomes 50 sec/div).
Saving Screen images to a USB flash drive
The Model 2522C oscilloscope supports saving of screen data
to a USB flash drive. To save, simply press down the SAVE
ALL button first, then press down DATA OUT. The Transfer
light next to it will flash or lid up. This means data is being
transferred to USB drive connected in the rear USB port.
When transfer is done, light will turn off. Press back up the
DATA OUT button when finished.
