DO NOT EXCEED COMPLIANCE VOLTAGE.
multimeter to supply the excitation for multiple E1586A Terminal Panels,
the resultant voltage sum of the voltages developed across the thermistors
could exceed the compliance voltage of the multimeter. This is especially
true if attempting to excite all three thermistors on the Terminal Panels.
In this configuration, a single Terminal Panel is used to provide up to 32
channels for temperature measurements. This provides the excitation
current to all three on-board thermistors on the Terminal Panel. Figure 1-17
shows connections for a single Terminal Panel.
Figure 1-17. Connecting Three Thermistors on a Single Panel
In this configuration, two Terminal Panels are used to provide up to 64
channels for temperature measurements. This provides the excitation
current to all six on-board thermistors on the Terminal Panels. Figure 1-18
shows the connection for two Terminal Panels.
