"_" Function 7.2 General Operation Flowchart The four display modes of the 8900 are layered as shown in the flowchart below. Keypad symbols illustrate basic navigation within and between these modes. • View: This is the default mode upon supplying power to the instrument. After system set-up is complete, all measurement values for each channel, plus the status of any analog outputs and relays will be available. -
Page 22: View Mode
7.3.2 Measurement Display Screens • The 8900 has a two-line display screen, like all the other ProcessPro instruments, but 8900 users choose to display either one or two measurements per screen. • In fact, four measurement display screens are independently configurable for single-measurement format, or dual-measurement format, according to user preference. -
Page 23: Derived Functions
Function Type of the Options menu. • The 8900 allows up to three derived functions to be used for display and control at any one time. An example of the display for derived functions is shown here. This format cannot be modified. -
Page 24: System Configuration
The Menu Directory may also be reached from any item in View by pressing and holding the ENTER button for two seconds. • The Menu Directory provides access to the seven separate menus of the 8900: System Setup, Channel Settings, Hold Inputs, Relay, Output, Calibration, and Options. -
Page 25: Menus
When power is applied to the 8900 it automatically recognizes the types of plug-in modules installed and adjusts menu content accordingly. For example, there will be no reference to channels 3 and 4, in any of the menus, if an I/O Module containing only two inputs is installed. -
Page 26: Pre-Configuration Guidelines
Note: b. and c. can only be remedied after sensors are connected. Remove power from the unit. All settings will be saved indefinitely in the non-volatile memory. 10. 8900 systems may be transported from one location to another with plug-in modules installed. 8.1.2... -
Page 27: System Setup
8.2 System Setup In terms of getting started and making measurements, System Setup is the most important menu in the 8900. And, the first and most important item in this menu is the Channel Type selection. Accessibility or content of virtually all items in every menu is reliant upon the association of measurement types with channels. -

(150 x (48 - 25)) - (205 x (23 - 25)) 3860 • The 8900 calculates PPM or PPB by dividing the µS value by a TDS Factor that you define. • TDS factors can vary widely, ranging from 1.50 to 2.50 µS per PPM. -
Page 45: Appendix D: Usp Limits
Using the USP function USP setpoints are defined as a percentage below the USP limit, so a USP alarm is always a HIGH alarm. The 8900 can be set to warn you if the conductivity approaches within a set percentage of the USP limit. -
