Why are my Conductivity/TDS/Resistivity readings unstable on Myron L Analytical Instruments?
Unstable readings in Conductivity, TDS, or Resistivity measurements with Myron L Analytical Instruments can often be traced to dirty electrodes. Cleaning the electrodes can resolve this. Also, ensure that the test samples have appropriate conductivity, especially if they are greater than 1 megohm.
What to do if Myron L ULTRAMETER II 6P have no display even when the measurement key is pressed?
If your Myron L 6P Analytical Instrument shows no display when you press the measurement key, the battery may be weak or not properly connected. Check the battery connections and replace the battery if necessary.
Why are the pH readings inaccurate on my Myron L 6P Analytical Instruments?
Inaccurate pH readings on your Myron L 6P Analytical Instruments can stem from several causes. It could be due to the need for pH calibration. Another potential cause is cross-contamination from residual pH buffers or samples in the sensor well, so ensure you clean the sensor well thoroughly. Also, using fresh pH buffers for calibration is important, as expired buffers can lead to inaccuracies.
What to do if Myron L 6P Analytical Instruments show no response to pH changes?
If your Myron L 6P Analytical Instruments show no response to pH changes, the sensor bulb might be cracked, or there could be an electromechanical short due to an internal crack. Inspect the sensor for damage and replace it if necessary.
Why are resistivity readings much lower than expected on Myron L ULTRAMETER II 6P Analytical Instruments?
If the resistivity readings on your Myron L Analytical Instruments are much lower than expected, it could be due to contamination from a previous sample or from the pH sensor well. Cleaning the pH sensor well and electrodes may help. Also, carbon dioxide in the test sample can cause this issue, so ensure your sample is free from carbon dioxide.
What to do if Myron L 6P Analytical Instruments will not adjust down to pH 7?
If your Myron L 6P Analytical Instruments will not adjust down to pH 7, it's possible that the pH/ORP sensor has lost KCl. Replenishing the KCl in the pH/ORP sensor should resolve this issue.
Why do pH readings drift on Myron L 6P Analytical Instruments?
Drifting pH readings or slow response to changes in buffers/samples, or repeated display of “FAC” on your Myron L 6P Analytical Instruments, can be caused by several factors. It may be a temporary condition due to the sensor's “memory” of a solution in the pH sensor well for extended periods; in this case, allow the sensor to stabilize. Alternatively, the bulb might be dirty or dried out, so clean the pH sensor bulb. A clogged or coated reference junction can also cause these issues; clear any blockage in the reference junction.
