• Start test icon reads the value of the resistor. The analyzer then converts this
value to conductivity by taking the inverse of the resistance and multiplying it by
the cell constant. This value is then compared to the expected value, assuming a
61.9 Kohm resistor. If the measured value is less than or equal to ±0.1 µS/cm of
the expected value, the test passes and the forward icon is enabled. Otherwise,
you are notified and must cancel the calibration.
