Aquametrix 2200R ORP Analyzer/Controller User Manual - Manual (Page 13)

Model 2200R Page 11
4.6 Operation Menu
4.6.1 The operation menu allows the user to recall and to adjust the parameters, required
by the analyzer functions.
4.6.2 When the analyzer is powered up, the program will display ORP readings and the
STATUS indicator above the display will be green. None of the LEDs in the
operation menu will be illuminated.
4.6.3 Five buttons on the panel are used to operate the menu. Use the CALL button to
step through the items in the menu. The red LEDs beside each menu item makes it
very easy to follow the menu. The function of the RUN button is to return to the on-
line ORP display from anywhere in the menu. The analyzer has a built-in timer
which returns the unit to the online mode if no button has been pressed for 10
minutes. This time-out has the same effect as pressing the RUN button.
4.6.4
When in the menu mode, the display initially shows the current value of the
parameters, such as the setpoint of the control relay, while putting all of the outputs
on hold. The two arrow buttons are used to adjust the display value up or down.
To accept the new value press ENTER twice. While the value on the display is
being changed, the relay outputs and the analog outputs remain on hold.
