8.5 Testing for Proper Operation
8.51 To make sure that your ionizing
air gun is working properly,
check the balance and discharge
levels. The performance of the
unit should be measured
periodically using a charged plate
monitor, such as the 3M™ 711
Charge Analyzer or the 3M™
713 Handheld Ionizer Tester.
8.52 Calibration should be performed
in accordance with the ESD
Association ionization standard
ANSI/ESD-S3.1, or the IEC
standard 61340-5-1, Figure
A.5.14. At a line pressure of 30
psi (2 bars), discharge of
+/- 1000 volts to +/- 100 volts
should require less than 1 second
at a distance of 6 inches (15 cm)
and balance should be /-
30 volts of zero.
