The glass bulb at the end of the electrode is sensitive to electrostatic
discharges. Avoid touching this glass bulb at all times.
During operation, ESD wrist straps should be worn to avoid possible
damage to the electrode by electrostatic discharges.
Any variation introduced by the user to the supplied equipment may
