The RS Series Resistance Substitution Box is the most commonly used decade box on the market today. The RS Series is not only easier to use, but it is also priced lower than most its competition.
Features:
• Direct reading — No fumbling with mulƟple slide or rotary switches
The IET family of digital subsƟtuters uses convenient side-by-side
thumbwheel switches. Simply dial in the desired values and use.
• Standard accuracies of 1%, 0.1%, and 0.05% available.
• Broad choice of standard and opƟonal models.
A full line of standard subsƟtuters saƟsfies most re quire ments.
• Direct readings eliminate potenƟal mistakes that come from
rotary or slide-switch boxes.
• For easy value readings, ranges are separated by color
coded switches and numbers.
• The units are small, rugged, and portable.
• CombinaƟon units, such as Resistance and Capacitance
SubsƟtuter (RCS-500), are available.
