Reference resistor:Meatest's M530 is a resistance standard set which is constructed to calibrate LCR meters in frequency that ranges from DC up to 100 MHz. The range of the frequency is attained through an applied HF layout which utilizes a strip line unit. The standards are made up of 4 coaxial BNC connectors.
Reference resistor:The RS3 range of resistance standards are constructed using carefully selected low temperature coefficient Manganin or Zeranin wire, depending on the value, mounted on formers which have a high mechanical stability. The wires are wound in a strain free manner and heat treated to remove any stresses. They are also artificially aged under the strictest control.
