9. Other settings
The following functions can be activated independently during operation by short-
circuiting connectors J1-J3, e.g. using a jumper or switch:
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.
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.
