If the meter doesn't read the correct value, it should be calibrated. If it doesn't calibrate (er.4), either the meter should be reset or the senor should be replace. Please check the video "how to solve Error 4 on LAQUAtwin meter"
The problem was that you do not say in your video to press again on cal, even if the right number does not ever come up. But I finally figured it out. @@horibainstrumentsinc.3082

What do I do if following these steps does not work? If it just keeps flashing through the calibration or has an error message or Or reading?
This means that the sensor needs to be replaced.
@@spiandbeyond Hi Dodie, thank you for your purchase, the price depends on the model. I hope that you are happy with the meter
@@horibainstrumentsinc.3082 I have had this same issue the first time I used the meter.
neex help, i put freshwater it is normal. when i out seawater, it show Or . can help ?
Hello which model do you use? OR means Over range.
what should the 150 and 2000 readings be for potassium when the meter is set to mmol? Thanks
The atomic mass of potassium is 39.0983. 150 ppm divided 39.0983 is about 3.84 mmol/L. 2000 ppm divided 39.0983 is about 51.15.
What do I do if the solutions do not read right on the meter, i.e., 150/2000? Is that what you are doing in that second part? I don't get it.
