578 Example 3497A ConfigurationsSAMPLE PROGRAMA sample program is shown to measure the resistances of 10 resistors with R1 connectedto channel AO, R2 to channel Al, etc. Since the Option 010 assembly is inslot 3, channel addresses are 60-69. The program sets a 1 mA output from the currentsource with the VC3 command. Thus, resistances R1 - R10 can be computedfrom Rx = Vx * 1000, where Vx is the channel voltage measured.SET INITIAL CONDITIONS10 PRlNT "2-WIRE RESISTANCE MEASUREMENTS"20 PRlNT30 PRlNT "RESISTOR";TAB(20);"0HMS"40 PRlNT50 CLEAR 70960 OUTPUT 709;"VC3" ~urfrnt souTe iraaMEASURE VOLTAGES ON CHANNELS 60-69 AND COMPUTE RESISTANCEE70 FOR I = 60 TO 69 S80 OUTPUT 709; "AC",I -+-- kC90 ENTER 709;A100 PRlNT TABIZ)A@TAB(I 8 ) @ q e -- V/Z110 NEXT I = Y/.OOI120 END =r \I%lao oTYPICAL PRINTOUT2-WIRE RESISTANCE MEASUREMENTSRESISTOROHMSCOMMENTSIf your application requires using the A Decade COMMON terminal to input currentfor A Decade (or B Decade) 2-wire resistance measurements, you can short out the100 ohm series resistors for more accuracy. However, see Chapter 8, Option 010description before doing this procedure.Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com
