There are 3 possible solutions:
1) If the electrostatic potential measured at the surface of the process required insulator exceeds 2,000 V, the item shall be kept a minimum of 30 cm from the ESDS; and
2) If the electrostatic potential measured at the surface of the process required insulator exceeds 125 V, the item shall be kept a minimum of 2,5 cm from the ESDS.
3) If the measured electrostatic field or surface potential exceeds the stated limits, ionization or other charge mitigating techniques shall be used.
