Page 5: Introduction
The Model 9340 is a Family of Precision Decade Resistance Boxes. It combines techniques established at Guildline in the construction and stabilizing of resistors, and low uncertainty switching techniques used in many of our instruments. The Model 9340 Series is available in decade range of from 3 to 7 decades. Each range is available in the full resistance range of from 0.01 ... -
Page 6: Features
1.3. GENERAL THEORY The 9340 series of decade boxes consist of 3, 4, 5, 6 or 7 decades of resistors switched in a series circuit. Figure 1-1 illustrates schematically the circuit of the Model 9347. The Models 9343, 9344, 9345, 9346 and 9347 are identical except for the number of decades. -

Page 12: Receipt And Inspection
Section 3 RECEIPT AND INSPECTION 3.1. 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 13: Operation And Maintenance
OPERATION AND MAINTENANCE 4.1. OPERATION The Model 9340 series of decade boxes are calibrated at the front panel red and black binding posts. The accuracy specification is determined as the resistance value offset from the zero selection resistance value. Above 1 k selection the zero resistance value is negligible. Below the 1 k selection the zero resistance value of the decade box needs to be taken into consideration to effect the specified accuracy. -
