Frequently Asked Questions - 6565FG YSI
How do I calibrate the YSI 6565FG dissolved oxygen sensor?
Calibrate the sensor using a two-point calibration at 100% air saturation and a zero solution (sodium sulfite). Follow the meter instructions for entering calibration mode.
What is the recommended storage procedure for the YSI 6565FG?
Always store the probe with the storage cap containing a moist sponge. Do not let the membrane dry out. Rinse with distilled water before storing in the cap.
How often should I replace the membrane cap?
Replace the membrane cap when it is wrinkled, damaged, or contaminated. Typically every 2 to 4 weeks with regular use, but replace immediately after rough handling.
Can I use the YSI 6565FG in saltwater?
Yes, the probe is designed for fresh and saltwater. Rinse thoroughly with clean water after each saltwater use to prevent salt crystallization on the membrane.
What does "Rapid Pulse" technology mean in this sensor?
Rapid Pulse technology is a YSI innovation that ensures more stable readings with less stirring dependence, allowing accurate measurement in low-flow environments.
How do I know when to change the electrolyte solution?
Change the electrolyte whenever the membrane cap is replaced or if measurements become erratic or slow. The solution should completely cover the electrodes inside the cap.
What is the temperature range for the YSI 6565FG sensor?
The sensor operates over a temperature range of 0 to 50°C. Automatic temperature compensation is provided by the built-in thermistor.
How do I clean the electrodes?
If readings are unstable, gently buff the silver anode with a fine abrasive pad, and polish the platinum cathode with a soft cloth. Rinse thoroughly before installing a new membrane.
Can I attach an extension cable to the YSI 6565FG?
Yes, optional extension cables are available, but ensure the total cable length does not exceed 50 meters to avoid signal degradation.
How do I perform a one-point calibration at 100% saturation?
Moisten the sponge in the calibration chamber, place the probe in it, and wait for temperature equilibrium. Then calibrate to 100% air saturation using the meter's menu.
