Page 15: Probe Maintenance
9. PROBE MAINTENANCE Periodic Maintenance Proper care and maintenance is essential for accurate readings. Cleaning, calibrating, and appropriate storage extends the life of the probe. • Inspect connector for corrosion and replace probe if necessary. • Inspect probe and cable for cracks or points of broken insulation. If any present, replace the probe. - Page 16 CAL Check™ & Cleaning (HI9813-61) To check meter’s calibration status: 1. Rinse the probe with water 2. Immerse the tip of the probe 4 cm (1 1/2”) into HI50021 calibration check solution. Note: A reading around pH 4.01 indicates that the probe is broken and requires replacement.
