Procedure Measure the guard voltage on internal channel 14.
MEASure:VOLT:DC? (@114)
The following example measures the guard voltage. The program assumes
the strain gage multiplexer is used with the HP E1326B/E1411B multimeter
as part of a scanning multimeter instrument. The computer syntax used is
HP BASIC running on a Hewlett-Packard Series 300 computer.
!Clear and reset the multimeter.
CLEAR 70903
OUTPUT 70903;"*RST"
!Measure the guard voltage on internal channel 14.
OUTPUT 70903;"MEAS:VOLT:DC? (@114)"
ENTER 70903;G_volt
!Print the guard voltage.
PRINT “Guard voltage = ”;G_volt
END
A typical output from this program is:
Guard voltage = 2.5233
