5.5 MENU TREE - ORP
The Model 3081 ORP 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 Std (standard) and tEMP
AdJ (temperature adjust). Under each sub-menu are prompts. For example, the Std sub-menu contains the single
prompt Std. Other sub-menus may contain more than one prompt. Figure 5-5 shows the complete menu tree.
5.6 DIAGNOSTIC MESSAGES - ORP
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
(Figure 5-1). The display alternates between the regular display and the diagnostic message. Figure 5-5 shows the
diagnostic fault messages for ORP.
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.
