The Energy Option 4

4-65. Limitations
The 6100B is an accurate reference source for independent voltage and current and
phantom power. Unlike power supplies, the 6100B has a closed loop feedback system to
ensure that the output waveforms are always of the demanded form. Extremely non-linear
loads such as the power supply of electronic meters disrupt the 6100B and 6101A ability
to maintain the correct output state. Attempting to provide line power to energy meters
from the 6100B system may cause the 6100B output to trip or result in inaccurate
readings. Always connect the meter’s auxiliary power supply to a suitable external power
source. The 6100B output capabilities are described in the specifications in Chapter 1.
The 6100B computed theoretical output power is accurate in Sine and Harmonic modes.
Adding Flicker, Dips, Fluctuating Harmonics or Interharmonics will reduce the accuracy
of the output power calculation and hence calculation of MUT error. If a reference meter
is used, measurement accuracy depends on the performance of the reference meter for
non-sinusoidal and amplitude modulated signal inputs. Negative power outputs are
accumulated as unsigned quantities. The user should apply a context to the displayed
magnitude of energy accumulated depending on the application and measurement
configuration.
4-66. Preparing to Use the Energy Option
Set the voltage and current output combinations for L1 (and L2 and L3) as required for
the test. See Chapters 3 and 4 for front-panel operating instructions. Enable the channels
that will be used, but do not turn the outputs on.
To enter the Energy mode, navigate to the Waveform Menu. Press until the top-level
softkey menu is displayed as shown in Figure 4-38.
