Seaward DO7e - Manual (Page 18)

20.2 In all measurements the P1 and P2 terminals are conventionally connected. Bear in
mind that thermal emfs may be present. The DO7e is particularly sensitive to these
on the 6m Ohm range.
20.3 For FS measurements, connect the C1 and C2 leads in the conventional manner (see
Fig 20.1).
20.4 For ZERO measurements, connect the C1 and C2 leads to the C2 terminal of the
standard (see Fig 20.2).
