Notice the level of charge on the 3M ™... - Page 14 Voltage range zero procedure: Perform zeroing on first power up. 1. Ground the 3M Charge Analyzer 711 by attaching the ground wire with alligator clip on the rear panel of ™ the unit to an earth/electrical ground. 2. Remove the plate electrode (b) from the Charge Analyzer.
- Page 15 If the “B” button (NO) is depressed you will return to the start of the DECAY TIME menu. The charge analyzer 711 is now ready to measure static charge neutralization effectiveness and the offset balance of ionizers.
- Page 16 Static decay time is defined as the time interval needed to reduce a defined voltage potential on an object to a defined lower potential by means of applied ionized air. Another important aspect for ionizers is the ability to produce a balanced stream of positive and negative ions. The 3M Charge Analyzer 711 can be used to ™...
- Page 17 1. Attach the three metal-spacers (j) by screwing into the three locations at the rear of the Charge Analyzer 711. ™ 2. Position the charge analyzer 711 in front of the ionizer blower with the display facing upward. 3. Measure the static decay rate and offset balance by following the procedure outlined in Demonstration #6 above.
