7-2
up phase 3 of a 3 phase instrument to simultaneously
measure the power of a single phase input (3 phase 2
wattmeter + phase 3 configuration). The frequency
reference for the independent phase 3 may be selected to
be voltage or current. In this mode, frequencies up to
1kHz can be measured with phase 3.
The 3 phase 2 wattmeter + phase 3 configuration can be
used as an additional Torque & Speed application to
supplement the existing “EXT” BNC connections on the
rear panel.
With the 3 phase 3 wattmeter configuration, each
measurement phase is connected to a phase of the load
with the voltage inputs measuring to neutral. In this mode,
phase to neutral voltages are measured directly and phase
to phase voltages are also computed.
The wiring configuration is the first item to be selected
under the ACQU menu.
