Resistance Standards

Resist-O-Stat Decade Boxes from Prime Technology

RDS Series are availabe in two versions- with basic accuracies of either ą0.025% or ą0.01%. Resistors used are low reactance types permitting the RDS to be used from dc through audio frequencies. Zero resistance is 0.0015 ohm/ decade. Numerical readout is positive and in-line. Switches are low noise "thermal" types with self-cleaning contacts

Features include:

	Total Resistance: 111.1 ohms to 111 Mohms
	Accuracy of 0.01% or 0.025%
	4, 5, 6 or 7 decades
	Complete with NIST traceable certificate.

Dial-An-Ohm Decade Boxes from Prime Technology

Dial-An-Ohm units (DA Series) provide reliable performance at less than one-half the cost of the RDS models, partly because DA thumbwheel switches are far less expensive than RDS rotary switches. The DA Series offers a choice of three mechanical configurations- a bench top model and two OEM versions.

Features include:

	Total Resistance: 111.1 ohms to 111 Mohms
	Accuracy of 0.1%, 0.01% and 1%
	3, 4, 5, 6 or 7 decades
	NIST traceable certificate available
