Operation
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.
IMPED LIMITS
Set min/max electrode sensor impedance limits.
DEFAULT SETUP
Resets all user-editable options to their factory-defaults.
DIAG/TEST
PROBE INFO
Display the sensor type, entered name of the sensor (Default: sensor serial number.), the sensor serial number, the
software version number, and the sensor driver version number.
CAL DATA
Displays the slope and the date of the last calibration.
SIGNALS
SENSOR SIGNAL: displays the sensor output in mV
SENSOR ADC COUNTS: displays the sensor ADC counts
TEMP ADC COUNTS: shows raw data for temperature ADC counts. ADC counts are comparable to A/D counts and are for
sensor electronic diagnostic purposes only.
ELECTRODE STATE: Identifies the state of the electrode (good or bad) depending on whether the impedance is within
preset limits.
ACTIVE ELECT: Shows the impedance (Mohms) of the active electrode if Imped Status is set to Enabled.
REF. ELECTRODE: Shows the impedance (Mohms) of the reference electrode if Imped Status is set to Enabled.
IMPED STATUS: Sensor diagnostic. Choose Enabled or Disabled.
COUNTERS
SENSOR DAYS: displays the cumulative days the sensor has been in use. RESET SENSOR: allows the sensor counter to
be reset to zero. ELECTRODE DAYS: Cumulative days the electrode has been in use.
