Why does my jenway 3520 display drifting erratic readings?
If your Jenway Multimeter displays drifting, erratic readings, the issue might stem from an electrode fault. To resolve this, test the 3520 using a BNC cap, and if necessary, replace the electrode.
What does ERROR SLOPE mean on my Jenway Multimeter?
If your Jenway Multimeter shows an 'ERROR SLOPE', it typically indicates an electrode problem. Try testing the 3520 with a BNC cap. If the issue persists, replace the electrode.
What to do if my jenway 3520 Multimeter is unable to recognise the buffer?
If your Jenway Multimeter is unable to recognize the buffer, ensure the buffer type is correct. Use AUTO for Jenway supplied buffers and replace the buffers if needed. You can also test the 3520 with a BNC cap and consider replacing the electrode.
Why can't I calibrate my Jenway Multimeter?
If your Jenway Multimeter won't calibrate, this is often due to an electrode fault. Test the 3520 using a BNC cap. If the problem continues, replace the electrode.
What does ERROR EO mean on my jenway 3520?
If your Jenway Multimeter displays 'ERROR EO', it indicates a buffer problem. Try using freshly prepared buffers to resolve this issue.
Why are temperature readings incorrect on my jenway 3520?
If your Jenway Multimeter temperature readings are incorrect, the temperature probe may be faulty. Check the 3520 and replace the temperature probe.
Why is the display erratic on my Jenway Multimeter?
If the display of your Jenway Multimeter is erratic, it might be due to the power supply. Make sure to use the supplied 9V ac power supply, as using other units can cause the 3520 not to operate correctly.
Why are temperature readings fluctuating on my Jenway Multimeter?
If your Jenway Multimeter temperature readings are fluctuating, it could be because of a faulty temperature probe. Check the 3520 and replace the temperature probe.
How to fix no display on Jenway Multimeter?
If your Jenway Multimeter display is blank, check the power supply. Ensure that the correct 9V ac power supply is properly connected and switched on.
What to do if Manual temp not set on my jenway 3520 Multimeter?
To address the 'Manual temp not set' message on your Jenway Multimeter, set the meter to read °C and adjust the temperature against a calibrated thermometer.
