Rev. 3.1
One of the most important features of the MICRO 200
BW is the ease of operation. You simply press the
Function Key, <F1-F5> for the selection you want to
access on the LCD screen.
The information contained in this manual will help
users take full advantage of the MICRO 200 BW’s
capabilities. In the event that unusual circumstances
arise that are not addressed in the manual, contact your
local distributor. Our engineering staff is also available
to help you with your specific needs.

1. Menu Guide to the MICRO 200 BW
The following pages guide you through the menus in
MICRO 200 BW and provide insight on how to use
each of them. Probably the best way to learn the system
is by “hands on training”. After reading this section in
its entirety the user should follow through each of the
menus on the MICRO 200 BW. The user will find that
each of the menus is arranged in a logical manner. After
going through each of the menus once he will gain a
familiarity with the structure. Each function is clearly
labeled. A menu flow chart figure 26 is provided on
page 44 for further clarity.
The functions of F1-F5 will vary according to the
menu. The function will be shown beside each button.
The absence of a function beside a button indicates that
the button is not used in that menu.
The following buttons always retain the function de-
scribed below:
ALARM:
Turns alarm contacts to “OFF”. Once an
alarm condition is met, the display will
continue to flash until the alarm condition
is removed. Once the alarm level has been
exceeded, either Hi or Lo, the alarms will
reset when the alarm condition has re-
turned to non-alarm value, including the
dead band value.
Once the alarm button is pushed the alarm
relay is inactive until the reading has once
again reached a non-alarm value (keep in
mind the dead band value). After this the
alarm level must be once again exceeded
before the alarm contacts can again close.
MENU:
Display will change to the next highest
level or previous menu. If this button is
pushed several times you will always re-
turn to the MAIN MENU. This button is
also used to return to the turbidity display
once the range has been selected.
NOTE: There are places of selection, for instance, alarm
limits, graphic limits and time set where it is
possible to set a parameter which is not viable.
An example is the 13th month of the year in
Time Set, or the Hi Alarm limit set lower than
the Low Alarm limit. When this happens you
will be disallowed from leaving that menu and
the effect will be that the menu button will not
work. Examine and correct the parameters to
proceed.
