Common Menus

Common Menus
The menu system shares certain modes between sensor types.
The following describes the EDIT Mode menus found in common between most sensor types.
NOTE:
Menu and Mode displays shown are examples only.
Your displays may vary.
INPUT Menu
(ALL) Manually select Sensor Type (See page 25 for further instruction).
Allows user to reset 9900 Transmitter to Factory settings.
Note: User is strongly discouraged from changing the sensor type away from the correct sensor.
The following can individually be set for each current loop

LOOP Menu

(Loop1 = 9900 base unit, Loop2 = Output Module)
(pH, COND/RES, LEVEL, SALINITY, DO only)
Set LOOP output source; select between Primary and Secondary measurements of applicable sensor.
Secondary measurements: DO, pH, COND/RES, and SALINITY = TEMP; LEVEL = VOL.
(COND/RES only) Select LIN/LOG. Default = LIN.
See LOG Current LOOP Output discussion in Appendix.
(ALL) Set value corresponding to desired 4 mA output. 5 digits max. Default = 0 (ORP = -999).
(ALL) (Not shown in COND/RES LOG Mode)
Set value corresponding to desired 20 mA output. 5 digits max.
Defaults = 100 (Flow, Cond/Res, Temp), 14 (pH), 1000 (ORP), 10 (Lvl/Prs), 5 (4 to 20 mA), 80 (Sal).
(ALL) Set desired LOOP output value when sensor error (e.g., bad sensor, broken wire) is detected.
Select (3.6 mA, 22 mA). Default = 22.
(ALL) Allows fi ne-tuning to compensate for errors in other equipment connected to the 9900.
Adjust the minimum and maximum current output. The display value represents the precise current output.
Adjustment limits: from 3.80 mA minimum to 5.00 mA maximum. Default = 4.00 mA.
(ALL) Allows fi ne-tuning to compensate for errors in other equipment connected to the 9900. Adjust
the minimum and maximum current output. The display value represents the precise current output.
Adjustment limits: from 19.00 mA minimum to 21.00 mA maximum. Default = 20 mA.
(ALL) Press ▲ or ▼ to manually order any output current value from 3.8 mA to 21.00 mA to test the
output of LOOP.
System Start-up: Step 4
Customize your 9900 to your own installed sensors.
