  If the ITW Measuring Instruments display shows ERROR, it may be due to a sensor malfunction, requiring repair or replacement. Another cause could be that the sensor plate cannot be charged up to 1 kV. In this case, you should clean the plate and insulators and dry them completely in a desiccator or in a poly bag using desiccant. If cleaning and drying doesn't help, repair or replacement may be needed due to a malfunction of the HV unit or the wirings.

  If the LCD of your ITW Measuring Instruments shows nothing or a part is missing, it could be due to no battery or a low battery, so charge the battery. It may also indicate a malfunction of the battery, in which case repair or replacement of the battery is needed. Another possibility is a malfunction of the LCD itself, requiring repair or replacement of the LCD or PCB.

What to do if ITW Simco-Ion EA-5J Measuring Instruments display shows dwindle voltage?

  If the display of your ITW Measuring Instruments shows dwindle voltage without ionization in the decay time measurement mode, or the indicated voltage is low in ion balance mode, it could be due to low insulation resistance of the plate sensor because of dirt or condensation on the plate insulation. To resolve this, clean the plate and insulators and dry them completely in a desiccator or in a poly bag using desiccant. If there's no improvement after cleaning and drying, repair or replacement may be needed.
