DISPLAY AND OPERATION
5.1. DISPLAY
The Model Xmt-P has a two-line dis-
play. Generally, the user can pro-
gram the transmitter to show one of
three displays. If the transmitter has
been configured to measure ORP or
Redox, similar displays are avail-
able. Figure 5-1 shows the displays
available for pH.
The transmitter has information
screens that supplement the data in
the main display. Press q to view
the information screens. The first
information screen shows the type
of measurement being made (pH,
ORP, Redox). The last information
screen is the software version
number.
During calibration and program-
ming, key presses cause different
displays to appear. The displays are
self-explanatory and guide the user
step-by-step through the procedure.
5.2 KEYPAD
Figure 5-2 shows the Solu Comp
Xmt keypad.
FIGURE 5-1. Displays During Normal Operation
Screen A shows the pH reading, the temperature, and the output current gen-
erated by the transmitter. Screen B shows the same information as Screen A
except the output current has been substituted with the raw sensor voltage.
Screen C 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.
