If the FMC Measuring Instruments LCD reads 'Check Probe Wire', it indicates a problem with the probe connection. You should check the lead from the electronic assembly to the probe to ensure it is securely attached and not loose. Also, verify that the probe is not empty.
Why does my FMC Measuring Instruments probe read high water cut values or 'Over Range'?
If the FMC Measuring Instruments probe displays high water cut values or reads 'Over Range', it could be due to several reasons: the probe is full of water, there's a conductive buildup on the insulators, or the insulators are shorted. To resolve this, remove the probe and inspect it for water, conductive buildup, or shorted insulators.
What to do if the FMC INVALCO WCM 7300 Measuring Instruments LCD goes to 0.00?
If the Dk of the fluid decreases while going through the FMC Measuring Instruments probe, the LCD will display 0.00. To fix this, reprogram and recalibrate the device starting from the 'Below Cal Zero' reading.
Why does the indicated water cut go up with an increase in temperature on my FMC INVALCO WCM 7300?
If the indicated water cut increases with a temperature increase in your FMC Measuring Instruments, the manual TC number is too high. You should reduce the manual TC number.
What to do if the indicated cut goes down with a temperature increase on FMC INVALCO WCM 7300?
If the indicated cut decreases with a temperature increase on your FMC Measuring Instruments, it means you need to increase the TC value.
