5.2 Selecting the Cell Constant
The meter includes a probe with a nominal cell constant (k) of 1.0. Use
probes with k = 0.1 and 10 (not provided) for improved performance
in extreme samples. Use this setup function to change the cell constant
if necessary. Meter default is 1.0 to match the probe supplied with the
meter.
k = 0.1 ideal for low measurements <20
μ
S/cm (<10 ppm).
k = 1.0 ideal for mid-range measurements
k = 10 ideal for high measurements >20 mS/cm (>10 ppt).
