Voltage and Resistance Measurements
The strain gage multiplexers can be used for DC voltage and 2-wire ohms
measurements. When making these measurements on the bridge
completion channels, the channel’s bridge selection jumper must be set to
the FULL position. DC voltages and resistances are connected to the HI,
LO, and G (guard) terminals of the bridge completion channels. If you are
using an HP E1326B/E1411B Multimeter, the guard lead must be
connected.
Note Two-wire resistance measurements with an HP E1357A or E1358A FET
Strain Gage Multiplexer will be in error by hundreds of ohms. This is due
to the "on resistance" of the FET which is in series with resistance being
measured. Refer to the HP E1326B/E1411B Multimeter User’s Manual for
information on DC voltage and resistance measurements.
