4.3 PROGRAMMING AND CALIBRATING THE SOLU COMP II
— TUTORIAL
Setting up and calibrating the Solu Comp II analyzer is easy. The following
tutorial describes how to move around in the programming menus. For prac-
tice, the tutorial also describes how to assign turbidity values to the 4 and
20 mA outputs for sensor 1.
1.
If the MENU screen (shown at the left) is not already showing, press
MENU.
Calibrate
is blinking, which means the cursor is on
Calibrate
.
2.
To assign tubidity values to current outputs, the
Program
sub-menu must
be open. Press
. The cursor moves to
Program
(
Program
blinking).
Press ENTER. Pressing ENTER opens the
Program
sub-menu.
3.
The
Program
sub-menu permits the user to set outputs, alarms (option -
60 only), and a security code, as well as choose between turbidity or TSS.
When the sub-menu opens,
Outputs
is blinking, which means the cursor
is on Outputs. Press
or
(or any arrow key) to move the cursor around
the display. Move the cursor to
>>
and press ENTER to cause a second
screen with more program items to appear. There are three screens in the
Program
menu. Pressing
>>
and ENTER in the third screen causes the
display to return to the first screen (
Outputs
,
Alarms
,
Measurement
).
4.
For practice, assign turbidity values to the 4 and 20 mA outputs for sen-
sor 1. Move the cursor to
Outputs
and press ENTER.
5.
The screen shown at left appears. The cursor is on
Output Range
(blink-
ing). Output range is used to assign values to the low and high current
outputs. Press ENTER.
6.
For a dual input analyzer, the screen shown at left appears. The dual input
analyzer has two outputs, one for each sensor. Move the cursor to the
desired output and press ENTER. For this example, choose
Output 1
.
For a single input analyzer, this screen does not appear. Instead, the
screen in step 7 appears.
7.
The screen shown at left appears.
Out1 S1
in the top line means output
1 (
Out1
) is assigned to sensor 1 (
S1
). For a dual input analyzer, either
output can be assigned to either sensor (sensor and output assignments
are made under the
Output Configure
menu shown in step 5). Use the
Out1 S1 Range?
screen to assign a turbidity value to the
4 mA
output.
a.
Use the arrow keys to change the pH to the desired value. Press
or
to move the cursor from digit to digit. Press
or
to increase
or decrease the value of the digit. Holding
or
down causes the
numeral to continuously scroll up or down.
b.
To move the decimal point, press
or
until the cursor is on the
decimal point. Press
to move the decimal point to the right. Press
to move the decimal point to the left.
c.
Press ENTER to store the setting.
8.
The screen shown at left appears. Use this screen to assign a full scale
pH value to the
20 mA
output. Use the arrow keys to change the turbidi-
ty to the desired value. Press ENTER to store the setting.
9.
The screen shown at left appears. To assign turbidity values to the low
and high currents for output 2, select
Output 2
and follow the prompts.
10. To return to the main menu, press MENU. To return to the main display
press MENU then EXIT, or press EXIT repeatedly until the main display
appears. To return to the previous display press EXIT.
NOTE
To store values or settings, press ENTER before pressing EXIT.
