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 2-5) to route the HP E1415's on-board current source
to a thermistor or RTD on a remote isothermal reference block. Figure 2-4
and Figure 2-5 show connections for both local and remote sensing. See
"Connecting the On-board Thermistor" on page 42. for location of J1.
