How to fix a blank display on YSI Measuring Instruments?
If your YSI Measuring Instruments display is blank, first, replace the batteries or test the power supply. If you're using a 5011 adapter, unplug it from the power supply connector. If the issue persists, it could be an internal power supply failure, in which case you should verify circuit operation using a DVM and consider replacing the PCB.
What to do if YSI Measuring Instruments show error E2: Check Membrane?
If your YSI Measuring Instruments show 'E2: Check Membrane', it could be due to high background current (DO), so refer to the calibration procedure. Also, check the probe zeroing procedure. The probe may need servicing, so follow the probe maintenance instructions, or the probe might be malfunctioning, requiring repair or replacement.
What does error E1 mean on YSI Measuring Instruments and how to fix it?
If your YSI Measuring Instruments display 'E1: Check Probe', begin by checking the probe connection. If the connection is not the issue, there may be an intermittent connection in the cable or plug, which would need repair or replacement. Also, the probe thermistor may be defective; it should measure 2252 ? @ 25oC, so replace the probe sensor assembly if needed. Another reason can be that the temperature is over range, so repair or replace the defective parts.
