6. Other settings
The following functions can be activated independently by short-circuiting
connectors J1-J3 by jumper or switch during operation:
J1: Graphical historic data display
The unit displays the stored values within
the set time base as a graphical trend. The
time base can be set to days (7, 14),
hours (1, 3, 6, 12, 24, 48, 72), minutes (3,
15, 30) or seconds (36).
The time base can be changed by
alternately opening and closing J1 (interval
< 2 sec). When first opening and closing
J1 the current time base is displayed. For
each subsequent opening and closing the
time base changes to the next setting. In
order to save the setting permanently, DIP
switch 10 must be switched from ON to
OFF position.
J2: Min-Max-display
The display shows the maximum and
minimum values recorded since the last
reset. The values can be reset by opening
and closing connection J2 shortly (interval
< 2 sec). The display shows "Minmax
reset".
J3: Auto-scaling
The device automatically changes the
upper scale caption depending on the
current measuring value, e.g. between 10,
100 and the set upper scale caption.
