Measurement functions for each scanner channel are defined using the FUNCTION menu when
building a scan. Measurement functions for this test would be set up as follows:
•
Channels 1 and 2: 4W Ω
•
Channels 3, 4, 5, and 8, 9, 10: 2 WΩ
Functions cannot be defined for channels 6 and 7 with this application because these channels are
paired with channels 1 and 2 for 4-pole switching.
Use the SCPI commands below to set up a combination 2- and 4-wire resistance test using the
DMM6500 and your 2000-SCAN.
*RST
Puts the DMM in a known state
FUNC 'FRES', (@1:2)
Sets the channels for 4-wire measurements
FRES:OCOM ON, (@1:2)
Turns on offset compensation
FRES:RANG 100, (@1:2)
Sets the 4-
wire range to 100 Ω
FUNC 'RES', (@3:5, 8:10)
Sets the channels to 2-wire measurement
RES:RANG 100e3, (@3:5, 8:10)
Sets the 2-
wire range to 100 kΩ
ROUT:SCAN:CRE (@1:5, 8:10)
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 combination 2- and 4-wire resistance test using the
DMM6500 and your 2000-SCAN.
reset()
Puts the DMM in a known state
channel.setdmm("1:2, dmm.ATTR_MEAS_FUNCTION,
dmm.FUNC_4W_RESISTANCE)
Sets channels for 4-wire
measurements
channel.setdmm("1:2", dmm.ATTR_MEAS_OFFCOMP_ENABLE,
dmm.OCOMP_ON)
Turns on offset compensation
channel.setdmm("1:2", dmm.ATTR_MEAS_RANGE, 100)
Sets 4-
wire range to 100 Ω
channel.setdmm("3:5, 8:10", dmm.ATTR_MEAS_FUNCTION,
dmm.FUNC_RESISTANCE)
Sets channels to 2-wire
measurement
channel.setdmm("3:5, 8:10", dmm.ATTR_MEAS_RANGE, 100e3)
Sets 2-
wire range to 100 kΩ
scan.create("1:5, 8:10")
Creates scan
scan.scancount = 1
Sets the scan count
defbuffer1.clear()
Clears buffer
trigger.model.initiate()
Initiates trigger model
