9.1.4 Characteristic Data from a Sensor Measured During Calibration
During calibration, calibration data and sensor status data (listed below) are acquired. However, if
the calibration is not properly conducted (an error occurs in automatic or semi-automatic calibration),
these data are not collected in the current calibration.
These data can be observed using parameter codes 「A20」 to 「A22」, and 「A50」 to 「A79」. For an
explanation and the operating procedures of individual data, consult Section 10.1, “Detailed Display.”
(1) Record of span correction ratio
Recorded the past ten span correction ratios.
(2) Record of zero correction ratio
Recorded the past ten zero correction ratios.
(3) Response time
You can monitor the response time provided that a two-point calibration has been done in semi-
automatic or automatic calibration.
(4) Cell’s internal resistance
The cell’s internal resistance gradually increases as the cell (sensor) deteriorates. You can
monitor the values measured during the latest calibration. However, these values include the
cell’s internal resistance and other wiring connection resistance. So, the cell’s degrading cannot
be estimated from these values only.
When only a span calibration has been made, these values will not be measured, and previously
measured values will remain.
(5) Robustness of a cell
The robustness of a cell is an index for predicting the remaining life of a sensor and is expressed
in a number on four levels.
