The Clarostat 250 is a rackmount Power Decade Resistor. It features six decades covering a range from 1 Ohms to 999.999 kOhms. All decades are constructed of viteous enamel-coated, wirewound power resistors. Resistance accuracy is 2% for decades of 1,10, 100, 1k, 10k, and 100k Ohms and 5% for the 1 Ohm decade. Connection is via front or rear panel binding posts.
