Operation

5.4pH Sensor Setup Menu (continued)

CONFIGURE (continued)

 

REJECT FREQ

Choose 50 or 60 Hz depending on the power line frequency for optimal noise rejection. Default is

 

60 Hz.

 

 

 

 

 

 

FILTER

Select 0–60 second signal averaging time.

 

 

 

 

TEMP ELEMENT

Select type of temperature element from the displayed choices.

 

 

 

 

SELECT BUFFER

Select the buffer type (standard 4, 7, 10 or DIN 19267) from the displayed choices.

 

 

 

 

 

Allows the user to specify that ammonia, morpholine, or other user-defined electrolyte is being

 

PURE H20 COMP

used in the application, allowing a temperature-dependent linear slope factor to be applied to the

 

 

measured pH.

 

 

 

 

CAL DAYS

Number of days since the last calibration. Default notification at 60 days.

 

 

 

 

SENSOR DAYS

Number of days the sensor has been in operation. Default notification at 365 days.

 

 

 

 

DEFAULT SETUP

Resets all user-editable options to their factory-defaults.

 

 

 

DIAG/TEST

 

 

 

Display the sensor type, entered name of the sensor (Default: Digital Gateway serial number and

 

PROBE INFO

name), the sensor serial number, the software version number, and the sensor driver version

 

 

number.

 

 

 

 

CAL DATA

Displays the pH slope and the date of the last calibration.

 

 

 

 

 

SENSOR SIGNAL: Displays the sensor output in mV

 

 

SENSOR ADC COUNTS: Displays the sensor ADC counts

 

 

TEMP ADC COUNTS: Displays raw data for temperature ADC counts. ADC counts are

 

 

comparable to A/D counts and are for sensor electronic diagnostic purposes only.

 

SIGNALS

ELECTRODE STATE: Identifies the state of the electrode (good or bad) depending on whether

 

 

the impedance is within preset limits.

 

 

ACTIVE ELECT: Displays the impedance (Mohms) of the active electrode if Imped Status is set

 

 

to Enabled.

 

 

IMPED STATUS: Sensor diagnostic. Choose Enabled or Disabled.

 

 

 

 

 

SENSOR DAYS: Displays the cumulative days the sensor has been in use.

 

COUNTERS

RESET SENSOR: Allows the sensor counter to be reset to zero.

 

 

ELECTRODE DAYS: Cumulative days the electrode has been in use.
