Table 1 Spreadsheet column descriptions (continued)
Column header name Data description and example values
Check Std Value Value of the check standard that was used to verify
accuracy, for example: 7.00 pH–25 ºC (pH, temp-
compensated); 7.01 pH (pH, custom)
Check Std Units Check standard units, for example μS/cm.
Note: pH is not displayed here as it is included in the previous
column.
Check Std Graph Bar-graph showing the measurement in relation to the
acceptance limits. Example: “6.901 <—|—> 7.101”.
Check Std Status Status of the check standard reading. Example:
“Reading within limits”, “Reading outside limits”
Calibration Status
Status of the calibration that is in use. = current
calibration is valid; = calibration has expired.
Cal Date Date of calibration reading: stored in user-defined date
format
Cal Time Time of calibration reading: stored in user-defined
time format
Cal Operator ID The operator ID specified when the probe was
calibrated. Shows “- - -” if undefined.
Cal Slope Name Slope (pH or LDO) or cell constant (conductivity)
Cal Slope The slope value for the calibration
Cal Slope Aux Used by pH to give the percent of nominal slope
Cal Slope Units Units of the calibration slope. Example: “mV/pH” for
pH
Cal Offset Calibration offset value
Cal Offset Units Calibration offset units. Example: “mV” for pH.
Cal r² Calibration correlation coefficient without a unit (may
be blank)
