Hach HQ430d User Manual

Table 1 Spreadsheet column descriptions (continued)
Column header name Data description and example values
Any settings that affect the
reading, for example
“NaCl/Non-Linear”
Reading Message 1–4 Any message that was shown during the measurement,
for example “Out of limits”.
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)
Cal Number of Std’s Number of standards used during calibration, for example 5. May be blank
depending on record type, parameter type, and method settings.
Cal Std 1 Known value of the first calibration standard
Cal Std 1 Units Units of the first calibration standard
Cal Std 1 Primary Value Measured value of the first calibration standard
Cal Std 1 Primary Units Associated units for the calibration measurement
Cal Std 1 Supp Value Value of supplemental measurement, for example temperature
Cal Std 2–7 Known value of additional calibration standards, if used
Cal Std 2–7 Units Units of additional calibration standards, if used
Cal Std 2–7 Primary Value Measured values of additional calibration standards, if used
Cal Std 2–7 Primary Units Associated units for additional calibration measurements, if used
Cal Std 2–7 Supp Value Value of supplemental measurement, for example temperature
Cal Std Supp Units Units applicable to all secondary calibration readings. Example: “ºC” or “ºF” for
temperature
Cal Message 1–4 Any messages about the calibration
