General description of the
used ESI DB62
for sale.
The ESI DB62 In-line DEKABOX Decade Resistors are adjustable resistors that can be easily set to a resistance value for precision dc and audio frequency use. The DB62 consists of a metal case, three binding posts, and six decade resistance switch assemblies. Initial accuracy of resistance change from zero setting: ± (0.01% + 0.0005 ohm per decade) at 23° C. Long term stability: ± (0.02% + 0.001 ohm per decade) per year. Zero resistance: Less than 15 mohms. Number of decades: six. Total resistance; 11,111.1 ohms: 0.01 ohms per step, 111,111 ohms: 0.1 ohms per step, 1,111,110 ohms: 1 ohms per step, 11,111,100 ohms: 10 ohms per step. Long term accuracy: 0.02% at 1 M ohm to 100 ohm , 5% at 0.01 ohm. Short term accuracy: 0.01% at 1 M ohm to 100 ohm, 2% at 0.01 ohm. Power (mW/step): 100 at 1 M ohm, 1000 at 100 k ohm to 1 ohm, 160 at 0.01 ohm.
