The Tektronix S-30 Delta Standards Box provides a tool to calibrate the Type 130 L-C meter. It includes seven adjustable capacitors, one adjustable inductor, and two fixed resistors. Tektronix intended to check and adjust the capacitors using a standard audio RLC bridge, such as a General Radio 1650 or equivalent—this would allow the Type 130 capacitance ranges to be accurately calibrated to + or -1%.
