Closing the AT Tree Switch connects any channel in Bank 0 (i.e.,
channels 00 to 07) to the AT Tree Switch Terminals and to the H, L,
and G terminals of the Analog Bus connector.
•
Closing the BT Tree Switch connects any channel in Bank 1 (i.e.,
channels 08 to 15) to the BT Tree Switch Terminals and to the I+, I-,
and IG terminals of the Analog Bus connector.
•
Use the Tree Switch Terminals to connect measuring devices like the
HP E1326 Digital Multimeter.
Figure 3-2 shows how to connect channels 02 and 09 of a single module
switchbox to the AT Tree Switch Terminals and the Analog Bus connector
for voltage or 2-wire ohms measurements. Execute:
CLOS (@102,190,192)
OPEN (@102)
CLOS (@109)
102 closes channel 02,
190 closes the AT tree switch,
192 closes the AT2 tree switch.
Opens channel 02.
109 closes channel 09.
