SLOPES
View the slope and calibration status for each electrode (PASS,
FAIL or INVALID). Anelectrode with a PASS status indicates
the last calibration was successful and the electrode is currently cali-
brated. A FAIL status indicates that an error occurred during the
last calibration. INVALID indicates that the calibration status has
become invalid after the calibration; for example, the reagent module
has expired.
The acceptable slope ranges are:
pH 55.00 - 65.00
