CALIBRATION PRINTOUT (FOR HI92240 ONLY)
During calibration, the characteristics of the electrode will be printed
to record the electrode's performance over time.
After the first point calibration a first set of
data will be printed. This will consist of:
date, time, the temperature compensated
pH buffer solution value and the offset char-
acteristic of the electrode in pH units.
The offset pH value should be between ±0.50pH. If values are
higher than +0.50 or lower than -0.50pH, the electrode is no
longer reliable and should be replaced.
After the second point calibration, a second
set of data will be printed. This will consist
of: date, time, temperature compensated pH
buffer solution value and the slope charac-
teristic of the pH electrode in percentage of
the theoretical value of 58.17mV per pH at
20°C.
