50 Using the Relay Multiplexer Chapter 2
Example: Scanning
Multimeter Resistance
Measurements
This program uses an E1406A Command Module to verify the E1460A
multiplexer will work in one-wire mode for resistance measurements with

the E1411B multimeter when the two are instruments are configured as a
scanning multimeter.
For this example to work in either switchbox or scanning multimeter mode,
you must externally connect the HI current source banana jack to the HI
input banana jack and the LO current Source/COM to the LO input banana
jack on the front panel of the E1411B multimeter.
For this example, the following resistors are connected to the one-wire COM
terminal. The remaining channels are open.
1 k on channel 00 HI
1.5 k on channel 00 LO
1.2 k on channel 01 HI
1.8 k on channel 01 LO
A typical result returns HEWLETT-PACKARD,E1411B,0,A.04.02 in response
to the *IDN? command. Also, "If E1460A terminal module jumper 10 is cut
and jumpers 11, 12, and 13 are in place, ROUT:FUNC? will return "WIRE1""
is displayed.
The four channels with resistors connected return the nominal value of the
resistor, such as 1003.129 for channel 00 HI or 1489.102 for channel 00 LO.
All other channels return 9.9E+37 to indicate an open channel.
