What to do if Instrutech Measuring Instruments display shows “overpressure”?
If the Instrutech Measuring Instruments display indicates 'overpressure', it could be due to the system pressure exceeding 1000 Torr. In this case, you should reduce the pressure. Alternatively, it may be caused by faulty electronics, which would require repairing or replacing the CVM201 electronics.
Why are the readings noisy or erratic on my Instrutech Measuring Instruments?
If the readings from your Instrutech Measuring Instruments appear noisy or erratic, it could be due to loose cables or connections. Check and tighten all connections. Another potential cause is contamination. Inspect the gauge for any signs of contamination, such as particles, deposits, or discoloration on the gauge inlet. If contamination is suspected, the gauge may need to be returned to the factory for cleaning. Excessive vibration could also cause noisy readings, so ensure the gauge is not mounted in an area with significant vibration.
What does it mean when Instrutech Measuring Instruments display shows “Sensor Bad”?
If the Instrutech Measuring Instruments display shows 'Sensor Bad', this indicates that the sensor wire is damaged. To resolve this, replace the sensor inside the CVM201 module.
Why atmospheric pressure reads too high on Instrutech Measuring Instruments?
If the atmospheric pressure reading is too high and cannot be set to the correct value on your Instrutech Measuring Instruments, it may be due to contamination. In this case, return the device to the factory for possible cleaning. Another potential cause is a damaged sensor wire, which would require replacing the sensor inside the CVM201 module.
Why atmospheric pressure reads too low on Instrutech Measuring Instruments?
If the atmospheric pressure reading is too low and cannot be set to the correct value on your Instrutech Measuring Instruments, it could be due to a damaged sensor wire, requiring a replacement of the sensor inside the CVM201 module. Another possible cause is contamination, in which case you should return the device to the factory for cleaning.
Why Instrutech Measuring Instruments readings are different from expected pressure?
If the readings from your Instrutech Measuring Instruments appear very different from the expected pressure, it could be because the process gas differs from the gas used to calibrate the CVM201 Module, or the module hasn't been calibrated correctly. You should correct the readings for different gas thermal conductivity. Also, check that zero and span are adjusted correctly.
How to calibrate Instrutech Measuring Instruments if zero and span can’t be adjusted?
If you are unable to calibrate the gauge on your Instrutech Measuring Instruments, and the zero and span cannot be adjusted, it could be due to contamination. In this case, return it to the factory for possible cleaning. Alternatively, it could be caused by sensor failure, which means you should replace the sensor inside the CVM201 module.
What to do if the setpoint does not actuate on Instrutech Measuring Instruments?
If the setpoint on your Instrutech Measuring Instruments does not actuate, it is likely due to an incorrect setup. To resolve this, check the setpoint setup.
How to fix a blank display on Instrutech Measuring Instruments?
If the display of your Instrutech Measuring Instruments is off or blank, the cause is likely due to no power. Check the power supply and power cable to ensure they are properly connected and functioning.
