The Enhanced JitterBox performs like the standard JitterBox, but protects at even higher levels of interference. There are three tiers offered in either adjustable or custom sizes to help solve virtually any problem. Jitter is common in environments where monitors are close to each other, or near scanners, printers or other equipment. Other common sources of background magnetic fields are building switch panels, wall wiring, transformers, power lines, or even fluorescent light ballasts.
Jitter occurs when external background magnetic forces interfere with the monitor's internal fields.
Newer, larger and more sophisticated monitors are more susceptible to the interference than their predecessors. Generally, the stronger the background field, the more likely jitter will occur, however, even relatively weak magnetic fields will induce screen jitter if the difference between the monitor's refresh rate and the background field frequency is small. As an affordable solution, FMS developed the JitterBox, which is a specially engineered, adjustable casing that easily installs around the monitor. Now, with the introduction of the Enhanced JitterBox line, monitor problems with even exceptionally high levels of interference can be solved. If you believe that you are experiencing screen jitter, check with your facility manager or local electric utility to get a measurement of the ELF magnetic fields in your work area.
