Operation
The 1065 Power Decade Resistance Box is designed to meet the standard required for
educational, industrial and research & design applications.
Housed in a well ventilated, all-metal case, its compact construction makes it easily
transportable and when in use it takes up a minimum of bench space.
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.
Resistance is selected by dialing the value required using the rotary switches. This enables
precise setting with a clear unambiguous indication.
For example - to select 3k83:
• set the 1kΩ bank to 3
• the 100Ω bank to 8
• and the 10Ω bank to 3
The 1065 has low thermal 4mm binding posts allowing connection
via 4mm banana plugs, spades, or bare wires. Two connections red
and black connect to the resistance and the green terminal connects
to the case for screening purposes.
Note: Remember that all resistance boxes have a residual resistance, i.e. when the dials
are set to zero a small resistance remains. If you are making precision measurements or
recalibrating the instrument, this residual value must be subtracted from all measurements.
