2. ORP Calibration Solutions: Quinhydrone saturated: pH
4.01= +89 mV, pH 7.00= +266 mV.
3. pION Calibration Solutions: 1.00, 10.00, 100.0 ppb, ppm,
ppt (thousand).
4. Dissolved Oxygen: Zero ppm (Sodium sulfite, Na2SO3
in water), Air saturated water, 8.25 ppm.
Any two solutions can be used for AUTO
calibration however if solutions other than those listed
above are used for calibration then the calibration values
must be entered manually.
•
STAND is standardization, a single point calibration.
Standardizations are typically used to adjust the process reading
to agree with a laboratory determined “grab sample” reading.
•
MANUAL is a data entry screen. Manual calibration allows the
user to enter a concentration with the corresponding mV value
and a slope for an electrode. Laboratory generated calibration
data for an electrode can be input to a remote analyzer where
calibration is difficult or impractical.
•
TEMP allows the displayed temperature to be trimmed to agree
with actual process temperature.
