Using Two Power Analyzers
Measure W
RS
and W
TS
(RST phases must be correctly identified)
1.
Connect the R-phase of the power source to the black terminal of the input
voltage of power analyzer 1.
2.
Connect the S-phase of the power source to the red terminal of the input
voltage of power analyzer 1.
3.
Plug the R-phase of the device to be tested to the black terminal of the output
load of power analyzer 1. Do not short the R-phase of the load to the R-phase
of the input power source.
4.
Record the reading of W
RS
displayed on the ‘W’ LCD of power analyzer 1.
5.
Connect the T-phase of the power source to the black terminal of the input
voltage of power analyzer 2.
6.
Connect the S-phase of the power source to the red terminal of the input
voltage of power analyzer 2.
7.
Plug the T-phase of the device to be tested to the black terminal of the output
load. Do not short the T-phase of the device to be tested to the T-phase of the
input power source.
8.
Record the reading of W
TS
displayed on the Watt LCD of power analyzer 2.
