Calibration Tips
You only need one calibration for measurement throughout the entire range of
the meter. If a range was not calibrated, the meter automatically detects the
closest range calibrated and uses that calibration information. However, only
the ranges that were calibrated have maximum accuracy.
If you are measuring in ranges near to or greater than 20 mS/cm (10 ppt), or
near to or lower than 100 µS/cm (50 ppm), suggested calibration frequency
is at least weekly.
If you are measuring in the mid-ranges and you wash the probe in deionised
water and store it dry, suggested calibration frequency is at least monthly.
Wet the probe for 10 minutes before calibrating or taking readings to saturate
the probe surface and minimise drift. If you take measurements at extreme
temperatures, calibrate the meter at least once a week.
You should only use the probe specified for these meters. These probes have a
built-in temperature sensor. If you use a different probe without a temperature
sensor, you must measure the solution temperature separately and manually
enter the solution temperature.
