PURE WAT COEF (Pure Water Coefficient)
Choose
ENABLE
to automatically apply pure water temperature correction for
measurements below 2 µS/cm (ultra pure water).
Note: this option does not apply to Salinity mode.
TEMP COEFFICIENT (Linear)
The temperature coefficient is the amount of change in conductivity per degree
temperature (% per ºC). The factory default setting is a temperature coefficient of
2.1 % per ºC. For most applications this will provide good results. The meter
allows adjustment from 0.0 to 10.0.
Note: this option does not apply to Salinity mode.
Select 0.0 % for uncompensated measurements.
The temperature will be measured by the electrode and
displayed in measurement mode – but without compensation.
NORMALIZATION TEMPERATURE (ºC)
When Automatic Temperature Compensation is used, measurements are
adjusted by the temperature coefficient %, to the normalization temperature. This
value is adjustable from 15.0 to 35.0 ºC.
Use the normalization temperature that is referenced on your calibration
standard(s) – usually 25 ºC.
TDS FACTOR (TDS Mode Only)
The TDS conversion factor is a multiplication factor used to convert from
conductivity to TDS. The TDS conversion factor automatically adjusts the reading.
Select the desired TDS factor from 0.400 to 1.000.
CELL CONST (Cell Constant)
The AB200 kit includes a probe with a nominal cell constant (k) of 1.0.
Use probes with k = 0.1 and 10 (sold separately) for improved performance in
extreme sample ranges. The factory default is 1.0 to match the included probe.
Cell constant can be adjusted from 0.010 to 10.000.
k = 0.1 ideal for low measurements <20 µS (<10 ppm).
k = 1.0 ideal for mid-range measurements
k = 10 ideal for high measurements >20 mS (>10 ppt).
