Model 1000 Product Features

The Model 1000 is designed to be used in production environments to test for actual turns on toroidal cores. It is able to test single winding toroids as well as multiple windings. It automatically compensates for variations in core permeability. This circuit is protected by US Patent 4,990,860.


Several versions of the Model 1000 are available. The 1000-A offers a microprocessor controlled display that allows the use of an internal reference coil. This reference coil reduces temperature drift of the unit to less than .1% per 10 degree F (5 deg C). The 1000-A unit also offers auto-ranging to 5,000 turns.


The 1000-B uses the same circuit as the standard unit, but it is built into a larger case to accommodate core sizes typical of power transformers. It offers three ranges and will count form 1 to 20,00 turns. It is typically configured to operate at 400 Hz. The 1000-BMX is similar to the 1000-B unit, but includes a mobile cart to allow the tester to be shared among multiple work stations.
