Bio-Rad Model EG-1 Econo™ Gradient Monitor - Manual (Page 8)

Display Function
Bar Graph In the Conductivity mode, the Bar
Graph provides a graphic repre-
sentation of the buffer conductivi-
ty relative to the lower and upper
limits of the selected range. In the
Gradient mode, the Bar Graph
provides an indication of the
buffer conductivity relative to
buffer A and B. A flashing red
LED at either end of the Bar
Graph indicates an out of range
condition.
Mode Selector Allows selection of Conductivity
or Gradient mode.
Gradient For use only in the Gradient
Calibration mode. The Gradient Calibration
key activates a routine which
allows the user to enter conduc-
tivity values for buffer A and
buffer B by passing the desired
“A” and “B” solutions through
the flow cell. The values for A
and B are automatically estab-
lished as “0” and 100% full scale
and chart recorder output is
scaled accordingly.
