Configuration
Configuration is the process of enabling functional capability in the transmitter firmware for your
application. This section will enable you to systematically determine and configure the value or
status of each parameter required for your application. Many applications require only changing a
few of the default values already entered. While you are in the Configuration mode, two segments
of the bargraph will appear under the legend CONFIG at the top of your front panel. These
segments will flash if you are also in a Hold mode. To enter the Configuration mode, press the
CONFIG key. At the prompt, enter the four character Major passcode and press ENTER. If the
passcode is correct, the display will flash UNLOCKED and then change to the first item in the
configuration structure, CONFIG DISPLAY. You may then edit any of the parameters in the
Configuration mode. If the passcode is incorrect, the display will flash LOCKED and then change
to the first item in the configuration structure. You may view the parameters in this mode but will
not have the ability to change them. In the UNLOCKED condition, the analog output defaults to
3.8 mA. If you do not want this to happen, turn the HOLD feature on first.
CAUTION
!
Always exit the Configuration mode by pressing the Measure key before power is
turned off. This allows proper reinitialization of internal data base security checks.
Config Display
(Refer to “Structure Diagram 1” on page 38.)
This section of the structure enables you under
DISPLAY PRIMARY to specify the PRIMARY
SENSOR
as pH, ISE, or ORP. This choice configures your analyzer as a pH, ORP or ion selective
electrode transmitter. Only parameters pertinent to the specific measurement technology will
appear in the configuration software after this initial choice is made. If pH, you can further
specify the PRIMARY RESOLUTION as 0.1 or 0.01 pH. If ISE, you can further specify the
PRIMARY SCALE as 9.999, 99.99, 999.9, or 9999 ppm. This choice specifies the largest value
that may be displayed as well as the decimal placement in ppm.
