Figure 19: Four-wire resistance test equivalent circuit
Use the SCPI commands below to set up a 4-wire resistance test using the DMM6500 and your
2000-SCAN.
*RST
Puts the DMM in a known state
FUNC 'FRES', (@1:5)
Sets up the channels for 4-wire measurements
FRES:OCOM ON, (@1:5)
Turns on offset compensation
FRES:RANG 100, (@1)
Sets the range to 100 Ω
FRES:RANG 10, (@2:3)
Sets the range to 10 Ω
FRES:RANG 1, (@4:5)
Sets the range to 1 Ω
ROUT:SCAN:CRE (@1:5)
Creates the scan
ROUT:SCAN:COUN:SCAN 1
Sets the scan count
TRAC:CLE
Clears the buffer
INIT
Initiates the scan
Below is the TSP equivalent to set up a 4-wire resistance test using the DMM6500 and your
2000-SCAN.
reset()
Puts the DMM in a known state
channel.setdmm("1:5", dmm.ATTR_MEAS_FUNCTION,
dmm.FUNC_4W_RESISTANCE)
Sets up the channels for 4-wire
measurements
channel.setdmm("1:5", dmm.ATTR_MEAS_OFFCOMP_ENABLE,
dmm.OCOMP_ON)
Turns on offset compensation
channel.setdmm(1, dmm.ATTR_MEAS_RANGE, 100)
Sets the range to 100 Ω
channel.setdmm("2:3", dmm.ATTR_MEAS_RANGE, 10)
Sets the range to 10 Ω
channel.setdmm("4:5", dmm.ATTR_MEAS_RANGE, 1)
Sets the range to 1 Ω
scan.create("1:5")
Creates the scan
scan.scancount = 1
Sets the scan count
defbuffer1.clear()
Clears the buffer
trigger.model.initiate()
Initiates the scan
