Using the Relay Multiplexer Modules 35Chapter 3
Example: Connect
Channels 02 and 10 to
Tree Terminals for 4-Wire
Ohms Measurements
Figure 3-3 shows how to connect channels 02 and 10 of a single module
switchbox to their respective Tree Switch Terminals and the Analog Bus
connector for 4-wire ohms measurements. Execute:
CLOS (@102,110,190,191)
102 closes channel 02,
110 closes channel 10,
190 closes the AT tree switch,
and 191 closes the BT tree
switch.
Comments Opening the AT, BT, and AT2 Tree Switches. Use the
OPEN <channel_list> command to open the tree switches.
For example, to open the AT, BT, and AT2 Tree Switches, execute:
OPEN (@190,191,192)
Measuring with the E1326/E1411 Multimeters. The E1326/
E1411 Multimeters can directly measure channels of single or multiple
multiplexer modules in a scanning voltmeter configuration. The
multimeters, when correctly programmed, automatically close the
appropriate AT, BT, and AT2 Tree Switches. For more information,
see the E1326/E1411 User's Manual.
