7. The next selection is for timed scans. (This is the Timer control source in the trigger

keys to select a time interval and press ENTER to confirm.
8. Next, you are prompted for a reading count (RDG CNT). This can be less than, equal to,

stored in the buffer. The effects of these choices are further described in the scanning ex-
amples.
9. Press ENTER when done to return to the normal display. Note that scanned readings are
always stored in the buffer, up to the setting for RDG CNT.
