correspondent to the value of set Timer
7. The Timer value could be very long (up to 30 minutes), so the special automatic
decimation algorithm (LOG) is use to write the Graph R(t) at display (see Fig. 19)
8. The cursors of the Graph R(t) could be activated with
key at the end of
measurement. The cursors of the Graph R(t) could be moved with
or
keys
9. Press
