Page 2: Receipt And Inspection
RECEIPT AND INSPECTION GENERAL Remove the instrument from its shipping container. The instrument was thoroughly tested and inspected before shipment and should be free from any electrical or mechanical damage when received. Nevertheless, you should perform an inspection for physical damage, ensure all items on the packing list are present and test the instrument, electrically, as soon as possible after receipt. - Page 3 Table of Contents Page SECTION 1 – INTRODUCTION General Theory Figure 1-1 Decade Box Schematic Diagram SECTION 2 – SPECIFICATIONS Table 2-1 Resistance Specifications Table 2-2 Resistance Range and Resolution SECTION 3 – MAINTENANCE OM934X-4T-D-00 2 February 2017...

Page 4: Section 1 - Introduction
The Model 934X-4T is a four terminal variation of the Model 934X Series Precision Decade Resistance Boxes. It combines techniques established at Guildline in the construction and stabilizing of resistors, and low level switching techniques used in many of our instruments. Decade step values below the 1 ohm are arranged in a Kelvin Varley configuration. -
Page 5: General Theory
Section 1 - Introduction GENERAL THEORY The 934X-4T series wiring consists of 3, 4, 5, 6 or 7 decades of resistors switched in a four terminal series configuration. Figure 1-1 illustrates schematically the wiring of the 9347-4T model. The Models 9343, 9344, 9345, 9346 and 9347 are identical except for the number of decades. -

Page 9: Section 3 - Maintenance
Section 3 – Maintenance Maintenance: The model 934X-4T series of four terminal decade resistance boxes do not require any specific maintenance other than periodic verification of the resistance accuracy. The accuracy can be verified by measurement with a suitable long scale multi-meter of sufficient accuracy. The lower decade values below 1 ohm can be measured while setting the first step of the 1 ohm decade at the x1 position and calculating the differences in resistance value as the lower decades are switched through the 10 steps from 1 to 10.
