Structural features of the ammeter AST
Ammeters AST - instruments in which the measuring system is assembled by astatic scheme that reduces the effect of external magnetic fields up to allowable limits. The common axis of the device AST placed between two identical fastened a movable part. Acting on them at the same time cause the magnetic field torques mutually opposite directions that and balance the system.
Operating Environment AST
Ammeter AST under the terms of mechanical stress during operation applies to ordinary.
AST ammeters are designed for operation at temperatures from +10 ° C to +35 ° C. The relative humidity for optimum performance ammeter AST must not be more than 80% (at +30 º C).
