Using the IPM-400 as a Source (cont'd)
Calibrate RTD Inputs (cont'd)
Note—Four-Wire Connections:
The IPM-400 may be used to calibrate instruments requiring a four-
wire RTD connection. This connection is valid only when the lead
wires included with the meter are used to connect the meter directly
to the instrument. Use of longer wires can cause errors in the
output setting.
For long four-wire cable runs, use the three-wire connection and
connect both wires from one side of the RTD to jack number 1.
