9900 Transmitter

INPUT Menu

Enter string up to 13 characters (optional).
Default = MEAS TYPE PH.

Select °F or °C.
Default = °C.

Dampens display, output and relay response rates.
Select Low, Med, High, OFF. Default = OFF. (see discussion in Appendix).

NOTE:

Signet strongly recommends leaving averaging OFF for pH and Pressure measurements

(2751 preamp only, 9900 Generation IV or greater) Set AUTOMATED GLASS IMPEDANCE update time
from 0 to 1440 minutes.
Setting update time to 0 turns off automatic glass impedance updates. Default = 60 minutes.

(2751 preamp with memory chip enabled sensors only, 9900 Generation IV or greater)

High Impedance Warning

is activated when the AUTOMATED GLASS IMPEDANCE measurement is

greater than the Factory Glass Impedance by selected multiplier.
Select multiplier of 3, 4, 5, or OFF. Default = OFF.

NOTE:

Factory Glass Impedance can be found under the VIEW mode by pressing

►

on SENSOR DATA.

CAL Menu

Select AT SENSOR to perform calibration using the Signet 2750/2751 sensor electronics.
Select AT INSTRUMENT to perform calibration at the 9900 via EasyCal or manual calibration.
(See pH Calibration procedures in the Appendix.) Default = AT INSTRUMENT.

YES prevents relays from activating while making adjustments, and relays in PULSE mode will
suspend pulsing. 4 to 20 mA output is held until the user exits the CAL menu. Select YES/NO. Default = NO.

(CAL AT INSTRUMENT only) Press

►

to start the EasyCal process.

You will be prompted to enter your password. (See pH EasyCal procedure in the Appendix).

(CAL AT INSTRUMENT only) Applies a linear offset to the pH measurement. The ideal value is the average
pH of your application. (A sample of your application at process temperature is recommended) (See pH
Calibration procedures in the Appendix) Shows error message if offset too high.

(CAL AT INSTRUMENT only) Applies a slope to the pH measurement. The slope value and the standard
value must be at least 2 pH units apart. The ideal values are the minimum and maximum values of your
process. (See pH Calibration procedures in the Appendix.) Shows error message if slope is too low or high.

(CAL AT INSTRUMENT only) Applies a linear offset to the temperature measurement.
The ideal value is the average temperature of your application. "SAVING" will appear if offset is acceptable,
"ERR TOO LARGE TO CALIBRATE" if offset is outside of range.

(CAL AT INSTRUMENT only) Press

to reset pH Calibration to factory default.

(CAL AT INSTRUMENT only) Press
