Electrosound Resistance Substitution Box 1 to 999,999 Ohms in 1 Ohm Steps

A six decade resistance substitution box ideally suited to educational establishments.

• Box will simulate resistances from 1Ω to 999,999Ω in 1Ω steps
• Required resistance is set by selecting the correct value from six rotary decade switches which clearly indicate the value selected
• An additional 1kΩ resistor is provided connected between one of the terminals of the internal resistance and a third terminal so the unit can be used as an accurate potential divider
• All outputs are on 4mm terminals with 4mm sockets
• Housed in an ABS box with non-slip rubber feet
• Voltage rating 250V
• Power rating 600mW
• Dimensions 110 x 75 x 50mm
