Precision Power Resistance Box
0.1 to 120k
1% Accuracy
10W per resistor dissipation
In-line read-out
Mechanically and electrically robust
Fully Screened
The 1065 Power Decade Resistance Box is designed to meet the standard for educational, industrial and research & design applications. Housed in a well ventilated metal case its compact construction makes it easily transportable, and when in use it takes up a minimum of bench space.
Resistance ranges from 0.1 to 120k with a 1% accuracy. Each resistor has a power rating of 10W and the maximum working voltage is 500V.
Switch contact resistance has been kept to a minimum by the use of multi-wafer switches, each with four parallel, silver-plated, self-wiping contacts. The six in-line dials give a clear numerical readout of the selected resistance.
