SENSOR INPUT CONNECTIONS
The sensor input connectors J1 and J2 on the Model 1015 rear panel
provide connections for the First and Second Stage inputs. The
connector definitions are listed in Table 2-2.
Use a four-wire connection (Figure 2-1A) to avoid introducing IR
drops in the voltage sensing pair which causes temperature
measurement error. Use the alternate two-wire connection (Figure 2-
1B) in less critical applications where lead resistance is small and
small readout errors can be tolerated.
Lake Shore 36-Gauge Cryogenic wire is ideal for sensor connections.
The four Phosphor Bronze leads with Formvar insulation are bonded
together and color-coded red, green, clear and blue for easy wire
identification.
