GF 9950-10 Six Channel Transmitter
Setting to ON prevents relays from activating while making adjustments or calibrating.
Relays in PULSE mode will suspend pulsing. 4 to 20 mA outputs are held until the user exits the CAL
menu or turns it OFF. Press the

to select OFF/ON. Press ENTER to save.
Default = OFF
Select AT SENSOR to perform calibration using the GF 2751-2 Sensor Electronics.
Select AT INSTRUMENT to perform calibrations at the 9950 using the 3-2751-1, 3-2751-3, or 3-2751-4
electronics. (Refer to pH Calibration procedures, page 71).
Default = AT INSTRUMENT

(CAL AT INSTRUMENT only) Applies a linear offset to the temperature measurement.
"SAVING" will appear if offset is acceptable, "ERR TOO LARGE TO CALIBRATE" if offset is outside of
range.
(CAL AT INSTRUMENT only) Applies an offset 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. (Refer to pH Calibration procedures, page 71).
Shows error message if offset is 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. (Refer to pH Calibration procedures, page 71).
Shows error message if slope is too low or high.
