10.1 GENERAL
This section describes how to do the following:
1. assign ORP values to the 4 and 20 mA outputs,
2. set the current generated by the transmitter during hold,
3. set the current generated by the transmitter when a fault is detected,
4. change sensor diagnostic limits,
5. change the units of the displayed variables,
6. program a security code,
7. simulate output currents for testing.
Factory default settings are given in Table 10-1. If default settings are acceptable, the transmitter is ready for cal-
ibration. See Section 9.0, Calibration of ORP Measurements. There is no way to automatically reset the transmit-
ter to factory defaults. Settings must be returned to default values one at a time. Figure 5-5 shows the menu tree.
10.2 ENTERING AND LEAVING THE PROGRAM MENU
Press PROG on the infrared remote controller (IRC) to enter the Program menu. To save new settings, press
ENTER . To leave the Program menu without saving new values, press EXIT . Pressing EXIT with a prompt
showing returns the display to the first prompt in the sub-menu. Pressing EXIT again returns the transmitter
to the process display.
If program settings are protected with a security code, pressing PROG or CAL will cause the Id screen to
appear. Key in the security code and press ENTER . The first sub-menu will appear. For more information,
see Section 5.7, Security.
A transmitter adjacent to the one being programmed may pick up signals from the IRC. To avoid accidentally
changing settings, use a different security code for each nearby transmitter. See Section 5.7, Security, and Section
10.6, Display Units, for details.
