OPERATION • Turn the meter on and select the measurement mode: pH or EC/TDS. • Dip the probe in the sample to be measured. Under no circumstances the immersion shall be above the max. level indicated above. Stir gently until the display shows a stable reading. The EC/TDS displayed value is referenced to 25°C (77°F). • When testing a new sample, it is recommended to rinse the probe with some of the sample itself prior to measurement. This prevents likelihood of cross-contamination.
