Reference Temperature Sensing with the HP E1413
The terminal module provides an on-board thermistor for sensing isothermal
reference temperature of the terminal blocks. Also provided is a jumper set
(J1 in Figure 2-4) to route the HP E1413’s on-board current source to a
thermistor or RTD on a remote isothermal reference block. Figures 2-6 and
2-7 show connections for both local and remote sensing.
