NOTE: Each time the calibration mode is entered all calibration range
indicators will be cleared, but only the calibration data for the currently
selected range will be replaced.
NOTE: As with all combination pH/conductivity probes, at low
conductivity levels the fl ow of the pH electrolyte may affect the readings
and result in artifi cially high conductivity readings. To eliminate the
interference, low level conductivity or TDS/Salt measurements should be
taken with a meter that measures conductivity only.
