Model 6487 Reference Manual
Measurements and Sourcing Voltage
3-15
Programming example
— ohms measurements
The following command sequence will perform one zero-corrected resistance
measurement:
*RST
' Return 6487 to GPIB defaults.
FORM:ELEM READ,UNIT
' Measurement, units elements only.
SYST:ZCH ON
' Enable zero check.
RANG 2e-9
' Select the 2nA range.
INIT
' Trigger reading to be used as zero
' correction.
SYST:ZCOR:ACQ
' Use last reading taken as zero
' correct value.
SYST:ZCOR ON
' Perform zero correction.
RANG:AUTO ON
' Enable auto current range.
SOUR:VOLT:RANG 10
' Select 10V source range.
SOUR:VOLT 10
' Set voltage source output to 10V.
SOUR:VOLT:ILIM 2.5e-3
' Set current limit to 2.5mA.
SENS:OHMS ON
' Enable ohms function.
SOUR:VOLT:STAT ON
' Put voltage source in operate.
SYST:ZCH OFF
' Disable zero check.
READ?
' Trigger and return one reading.
Voltage source operation
Voltage source edit keys
The V-SOURCE and keys will operate in the same manner as the RANGE and keys if
they are not being used to change the voltage source values. The AUTO key acts as a
shortcut to set the V-SOURCE to 0V.
Configuring the voltage source
To set up the voltage source:
1.
Press CONFIG then OPER.
2.
Select either the DC mode for normal operation or SWEEP for voltage sweeps (see
for details on sweeps). Press ENTER.
3.
After the mode is selected, the reading disappears and is replaced with a full-
resolution value of the voltage source with the left-most position highlighted for
editing.
4.
Use the RANGE and arrows to change the voltage source range and indicate the
range selected (10V, 50V, or 500V).
