DISPLAY AND OPERATION
5.1. DISPLAY
The Model Xmt-A-FF has a two-line display.
Generally, the user can program the trans-
mitter to show one of two displays. If the
transmitter has been configured to measure
free chlorine with continuous pH correction,
more displays are available. Figure 5-1
shows the displays available for dissolved
oxygen.
The transmitter has information screens
that supplement the data in the main dis-
play. Press  to view the information
screens. The first information screen shows
the type of measurement being made (oxy-
gen, ozone, free chlorine, total chlorine, or
monochloramine). The last information
screen is the software version number.
During calibration and programming, key
presses cause different displays to appear.
The displays are self-explanatory and guide
the user step-by-step through the proce-
dure.
5.2 KEYPAD
Figure 5-2 shows the Solu Comp Xmt key-
pad.
FIGURE 5-1. Displays During Normal Operation
Screen A shows the dissolved oxygen reading, the temperature, and the out-
put current generated by the transmitter. Screen B shows the same information
as screen A except the output current has been substituted with the raw sen-
sor current. Screen B is most useful while troubleshooting sensor problems.
FIGURE 5-2. Solu Comp Xmt Keypad
Four arrow keys move the cursor around the screen. A blinking word or numer-
al show the position of the cursor. The arrow keys are also used to change the
value of a numeral. Pressing ENTER stores numbers and settings and moves
the display to the next screen. Pressing EXIT returns to the previous screen
without storing changes. Pressing MENU always causes the main menu
screen to appear. Pressing MENU followed by EXIT causes the main display
to appear.
