The following functions can be activated independently by short-circuiting
connectors J1-J3 by jumper or switch during operation:
J1: Graphical historic data display
To activate the graphical historic data
display connector J1 is shorted. 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 (6, 12, 24, 48, 72) or minutes (3, 15,
30, 60).
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.

To activate the Min-Max display connector

reset by opening and closing connection
J2 shortly (interval < 2 sec). The display
shows "Minmax reset".
J3: Auto-scaling
To activate auto-scaling J3 connector is
shorted. The device automatically changes
the upper scale caption depending on the
current measuring value between 10, 100
and the set upper scale caption.
