For example, to open the AT, BT, and AT2 Tree Switches, execute:
OPEN (@190,191,192)
Measuring with the HP E1326/E1411 Multimeters. The HP 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 HP E1326/E1411 User's Manual.
102 closes channel 02,
110 closes channel 10,
190 closes the AT tree switch,
and 191 closes the BT tree
switch.
