seconds.

NOTES
1.
The common measurements display does not have a designated indicator LED. If no
indicator LED is lit up below the display, this means that the common measurement
parameters are being displayed at this time. To return to the common measurements
from another group, just press the same key that you used to display this group (the key
pointed to by an illuminated LED) until the illuminated LED goes out.
2.
When you move to another measurement group, the instrument stores your last
location; when you return to the previous group, the instrument restores the last page.
At power up, the instrument always returns to the common measurements group and
shows you the last page that was displayed prior to loss of power.
