CALIBRATE THE CONDUCTIVITY PROBE:
Conductivity Probe require periodic calibration to maintain accuracy. Each probe is cali-
brated through a simple process of placing it into a standard solution of known quality,
at 25 °C (77 °F) following the prompts on the display.
The Conductivity calibration is done using one buffer solution (50 mS or 500 µS). Standard
buffer solution for marine is 50 mS, for fresh water is 500 µS. Set up a cup with the Elos
Calibration Solution.
IMPORTANT:
calibration solution MUST be kept at a Temperature around to 25 °C (77 °F).
Rinse the probe in the system water and shake it off. Do not scour the probe with any dry
towel!
Place the COnductivity probe into the Calibration Solution and start the calibration.
The controller will prompt you:
