Standard Functions
Adjustment Mode
For successful measurement of ORP, ORP value in the
sensor location, electrode performance and standard
solution accuracy respectively play an important role for
obtaining reliable data.
By setting the adjustment value, calibrates ORP value
indicated on the AER-101-ORP to read 260 mV (at 20 )
when immersing the ORP Combined Electrode Sensor in
the standard solution (Quinhydrone potential difference 260
mV).
Span Sensitivity
Correction Mode
By setting the Span sensitivity correction value in
percentage, calibrates ORP value indicated on the
AER-101-ORP to read 260 mV (at 20 ) when immersing
the ORP Combined Electrode Sensor in the standard
solution (Quinhydrone potential difference 260 mV).
