Figure 21: Four-wire resistance test equivalent circuit
Use the SCPI commands below to set up a 4-wire resistance test using the DMM6500 and your
2001-TCSCAN.
*RST
Puts the DMM in a known state
FUNC 'FRES', (@2:5)
Sets up the channels for 4-wire
measurements
FRES:OCOM ON, (@2:5)
Turns on offset compensation
FRES:RANG 100, (@2:3)
Sets the range to 100 Ω
FRES:RANG 10, (@4)
Sets the range to 10 Ω
FRES:RANG 1, (@5)
Sets the range to 1 Ω
ROUT:SCAN:CRE (@2:5)
Creates the scan
TRAC:CLE
Clears the buffer
INIT
Initiates the scan
Below are equivalent TSP commands to set a 4-wire resistance test using the DMM6500 and your
2001-TCSCAN.
reset()
Puts the DMM in a known
state
channel.setdmm("2:5", dmm.ATTR_MEAS_FUNCTION,
dmm.FUNC_4W_RESISTANCE)
Sets up the channels for 4-wire
measurements
channel.setdmm("2:5", dmm.ATTR_MEAS_OFFCOMP_ENABLE,
dmm.OCOMP_ON)
Turns on offset compensation
channel.setdmm("2:3", dmm.ATTR_MEAS_RANGE, 100)
Sets the range to 100 Ω
channel.setdmm("4", dmm.ATTR_MEAS_RANGE, 10)
Sets the range to 10 Ω
channel.setdmm("5", dmm.ATTR_MEAS_RANGE, 1)
Sets the range to 1 Ω
defbuffer1.clear()
Creates the scan
scan.create("2:5")
Clears the buffer
trigger.model.initiate()
Initiates the scan
