ITW SIMCO ION Aerostat Guardian - Ion Balance Check

Aerostat Guardian 5100650-M Rev 2 21
4.6 Ion Balance Check
To test the unit for ion balance, the use of a charge plate monitor
such as the Simco-Ion Model 280A is recommended. Offset voltage
should be measured and checked against the Ion Balance in
Section 5, Specifications.
Do not try to determine ion balance by holding a static meter in the
ionized air stream. This will result in a meaningless reading.
