Description
Module
For sensors connected to a pH/ORP module only—Shows the version and the serial
information
number for the sensor module.
Sensor
For sensors connected to a pH/ORP module—Shows the sensor name and the serial
information
number entered by the user.
For sensors connected to an sc digital gateway—Shows the sensor model number, and
the sensor name entered by the user and the sensor serial number. Shows the software
version and driver version installed.
Last calibration
For sensors connected to a pH/ORP module only—Shows the number of days since the
last calibration was done.
Calibration history
For sensors connected to a pH/ORP module—Shows the calibration slope and date of the
previous calibrations.
For sensors connected to an sc digital gateway—Shows the calibration slope and date of
the last calibration.
Reset calibration
For sensors connected to a pH/ORP module only—For service use only
history
Impedance status
For pH sensors only—Refer to
Sensor signals
For pH sensors connected to a pH/ORP module only—Shows the current reading in mV.
(or Signals)
For pH sensors connected to an sc digital gateway—Shows the current reading in mV and
the analog to digital converter counters.
If Impedance status is set to Enabled, shows the active and reference electrode
impedances.
Sensor days
For sensors connected to a pH/ORP module—Shows the number of days that the sensor
(or Counter)
has been in operation.
For sensors connected to an sc digital gateway—Shows the number of days that the
sensor and electrode(s) have been in operation. The Electrode days counter is reset to
zero when the firmware identifies that a defective electrode has been replaced with an
electrode that operates correctly.
To reset the Sensor days counter to zero, select Reset.
Reset the Sensor days counter when the sensor (or salt bridge) is replaced.
