None. In normal usage the cancelling systems should continue working without need for attention. The only exception are DC systems that need resetting under certain circumstances, such as when the DC sensor has been moved.
No. It automatically reacts to changes in both field frequency and magnitude.
They react in 100 microseconds. But note that the meters on the front panels (which have no effect on cancelling) are not fast enough to show this.
Spicer Consulting generally attaches room size cables to the wall in plastic trunking (38mm x 16mm). Where possible, the cables are routed under the floor or above the ceiling. In newly built or refurbished sites it may be possible to bury conduit in the walls and floor.Where room size installations are not possible cables are mounted using cable ties to the tool's cabinet or on a specially manufactured aluminium frame. Here are some details of installations we have carried out ourselves.
Not usually. Helmholtz frames are inconvenient for the user and no better than room size cables for cancelling beam movement. They are typically used for OEM installations and when other cable arrangements are not suitable.
A separate system is required for each tool.
Yes, but precautions are needed. Read more in the knowledge base.
Sometimes. It depends on the individual circumstances.
No. They only affect the level at which the Field OK light goes out and the trip indicators come on.
Yes, using the wideband DC sensor.
Yes, the system will permanently cancel changes from the DC field level since the last sensor reset.
The Sensor SC24/DC+AC has wide bandwidth (DC-13kHz) and when used with the System SC24, the system provides DC and AC field cancelling. You do not need an AC sensor as well.
The SC12 has been replaced by the SC22. We intend to support those sold as long as possible.
The SC15 was a 2-channel spectrum analyser module. It was withdrawn when the DAQCard it used was no longer available. The functionality of the SC15 is available using the SC11/SI with SC11 Transfer software.
The SC20 has been replaced by the SC24. We intend to support those sold as long as possible.
The SC20Fast has been replaced by the SC26. We intend to support those sold as long as possible.
Spicer Consulting cancelling systems have safety certification from CSA. These are listed on the CSA web site . The cancelling systems also conform to European CE directives. Full details are given in the user manual.
