Use the SCPI commands below to set up a 2-wire resistance test using the DMM6500 and your
2001-TCSCAN.
*RST
Puts the DMM in a known state
FUNC 'RES', (@2:4, 6:9)
Sets the channels for 2-wire measurements
RES:RANG 100e3, (@2:4, 6:9)
Sets the range to 100 kΩ
ROUT:SCAN:CRE (@2:4, 6:9)
Creates the scan
TRAC:CLE
Clears the buffer
INIT
Initiates the scan
Below are equivalent TSP commands to set a 2-wire resistance test using the DMM6500 and your
2001-TCSCAN.
reset()
Puts the DMM in a known
state
channel.setdmm("2:4, 6:9", dmm.ATTR_MEAS_FUNCTION,
dmm.FUNC_RESISTANCE)
Sets the channels for
2-wire measurements
channel.setdmm("2:4, 6:9", dmm.ATTR_MEAS_RANGE, 100e3)
Sets the range to 100 kΩ
scan.create("2:4, 6:9")
Creates the scan
defbuffer1.clear()
Clears the buffer
trigger.model.initiate()
Initiates the scan
Measurement accuracy can be optimized with minimal residual resistance. Make connecting wires as
short as practical and limit the number of connectors to minimize path resistance. You can also short
one of the scanner channel inputs, close the shorted channel, and enable the DMM REL feature to
null the path resistance. REL must be enabled for the entire test.
