Calibration Chart


Recalibration is required in the following conditions:
-Lengthy periods of inactivity
-Very frequent use
-The testing accuracy requirement is very high.
-The “CAL”(calibration ) button was pushed and electrode to air for extended period of time


Always replace protective cap after using digital meter to keep electrode from drying out due to proloned exposure to air ,which leads to slow or unstable readings. If electrode has been dried out immerse it into distilled water for a few hours.


When the display value is fuzzy or unshown , The battery should be replaced promptly.Pay attention to the polarity of battery.
