Frequently Asked Questions - 5200A YSI
How do I calibrate the YSI 5200A dissolved oxygen meter?
To calibrate, place the probe in water-saturated air (100% saturation) or a known standard. Press the CAL button and follow the prompts. For zero calibration, use a sodium sulfite solution.
How often should I replace the membrane?
Replace the membrane every 2-4 weeks or if it shows damage, wrinkles, or contamination. Frequent use in dirty water may require more frequent changes.
What type of electrolyte does the 5200A use?
The YSI 5200A uses a potassium chloride (KCl) electrolyte solution. Use only YSI-approved electrolyte to ensure accurate readings.
How do I clean the probe?
Rinse the probe with distilled water after each use. For stubborn deposits, use a mild detergent and a soft cloth. Do not use abrasive materials or solvents.
Can the 5200A be used in saltwater?
Yes, it can be used in saltwater. The meter has a salinity compensation feature. Enter the salinity value (in ppt) before measurement for accurate DO readings.
What is the battery life?
With a standard 9V alkaline battery, the 5200A can operate for approximately 100 hours of continuous use. Use a lithium battery for longer life.
How do I store the probe when not in use?
Store the probe with a moist sponge or in a storage solution to keep the membrane hydrated. Avoid letting it dry out. Remove the battery if storing for extended periods.
Can I log data directly to a computer?
Yes, the 5200A can be connected to a computer via an optional RS-232 or USB interface. Use YSI-compatible software to download logged data.
What does the error code 'E1' mean?
Error code E1 indicates a calibration error. Check that the probe is properly connected and that the calibration standard is correct. Recalibrate if necessary.
Is the YSI 5200A waterproof?
The probe is waterproof, but the meter body is splash-resistant only. Do not submerge the meter. Keep the connector dry.
