and Natural
Seawater Scale).
PSU, NaCl%, g/L NaCl% Not available.
EC Range (Not Available In Basic Mode)
The EC and TDS measurements may be congured in SETUP as AUTO (meaning
auto-ranging, the measurement automatically nds the correct conductivity
or TDS unit and resolution), or it may be congured with a user-selected
measurement range and resolution (if you know ahead of time where your
samples will fall). If AUTO is selected, the meter will select the scale with
the highest possible resolution, but may change in the middle of a series of
measurements changing units and displayed resolution).
Note: The selected range is only active during measurements. Auto-ranging
is used during calibration. If a xed range is selected and during measurement
goes beyond the range limits, the full scale value of that range will ash on
the display.
General Guidelines
Calibrate the instrument frequently, especially if high accuracy is required.
The instrument should be recalibrated:
• Whenever the EC probe is replaced.
• At least once a week.
• After testing aggressive chemicals.
• If “CAL DUE” is displayed on the 3rd LCD line.
