FIGURE 5-4. Menu Tree for pH
5.3 MENU TREE - pH
The Model 3081 pH transmitter has three menus: CALIBRATE, PROGRAM, and DIAGNOSE. Under the Calibrate and
Program menus are several sub-menus. For example, under CALIBRATE, the sub-menus are CALIbrAtE, Std (stan-
dard), and tEMP AdJ (temperature adjust). Under each sub-menu are prompts. For example, under Std, the prompts
are Std xx.xx and slope xx.xx. The DIAGNOSE menu lets the user view diagnostic messages. Figure 5-4 shows the
complete menu tree.
5.4 DIAGNOSTIC MESSAGES - pH
Whenever a warning or fault limit has been exceeded, the transmitter displays diagnostic messages to aid in trou-
bleshooting. Diagnostic messages appear in the same area as the temperature/output readings in the process display
screen (see Figure 5-1). The display alternates between the regular display and the diagnostic message. Figure 5-4
shows the diagnostic fault messages for pH.
If more than one warning or fault message has been generated, the messages appear alternately.
See Section 12.0, Troubleshooting, for the meanings of the fault and warning messages.
