Fluid pressure hazard. Removal of a sensor from a pressurized vessel can be dangerous. Reduce
the process pressure to below 7.25 psi (50 kPa) before removal. If this is not possible, use extreme
caution. Refer to the documentation supplied with the mounting hardware for more information.

Description
Refer to
Table
1.
Sets the time interval for sensor and temperature
measurement storage in the data log—5, 10, 15,
30 seconds, 1, 5, 10, 15 (default), 30 minutes, 1, 2, 6,
12 hours.
Selects the power line frequency to get the best noise
rejection. Options: 50 or 60 Hz (default).
Refer to
Table
1.
Refer to
Table
1.
For pH sensors only—Sets the pH buffers used for auto
correction calibration. Options: 4.00, 7.00,
10.00 (default set) or DIN 19267 (pH 1.09, 4.65, 6.79,
9.23, 12.75)
Note: Other buffers can be used if the 1-or 2-point manual
correction is selected for calibration.
Refer to
Table
1.
1-,2-,3- or 4-point matrix correction can also be
selected. The 1-,2-,3- or 4-point matrix correction are
compensation methods pre-programmed in the
firmware.
Sets a reminder for the next calibration (default:
60 days). A reminder to calibrate the sensor shows on
the display after the selected interval from the date of
the last calibration.
For example, if the date of the last calibration was June
15 and Last calibration is set to 60 days, a calibration
reminder shows on the display on August 14. If the
sensor is calibrated before August 14, on July 15, a
calibration reminder shows on the display on
September 13.
Sets a reminder for sensor replacement (default:
365 days). A reminder to replace the sensor shows on
the display after the selected interval.
The Sensor days counter shows on the
Diagnostics/Test > Counter menu.
When the sensor is replaced, reset the Sensor days
counter on the Diagnostics/Test > Counter menu.
Sets the low and high impedance limits for the Active
electrode and Reference electrode.
Sets the Settings menu to the factory default settings
and resets the counters. All sensor information is lost.
