100% Calibration Note... Only when the measurement value is above 50% can the meter be calibrated at 100%. All other keys except POWER ON/OFF and HOLD are inoperable while performing calibration. 1. Clean the probe thoroughly with deionized water. 2. Press RANGE to select the % saturation scale (see Fig. A). 3.
Page 20
0% Calibration Note... The measurement value must read below 10% to calibrate the meter at 0%. All other keys except POWER ON/OFF and HOLD are inoperable while performing calibration. 1. Clean the probe thoroughly with deionized water. 2. Press RANGE to select the % saturation scale (see Fig. A). 3.
