4-69. Type of Energy
It is necessary to set the type of energy being measured in the test: Real (Wh), Effective
(VAh) or Reactive (VARh). This setting should match the settings on the MUT and
reference meter(s). The meter constants then need to be specified. There is one value for
all MUT and one for all reference meters.
Note that the Instrument provides various methods of specifying Reactive (VAR) power
for non-sinusoidal output waveforms. The 6100B Energy Option always uses the
Budeanu method to calculate errors when Main Output is the reference. If the reference
source is an external reference meter, then calculation will be dependent upon the method
used by the reference meter.
4-70. Internal Pull-ups
Each input group (MUT and Reference) may have either 150 Ω or 1 kΩ pull-ups internal
to the 6100B. It is recommended that 150 Ω be selected when using higher frequency
pulse rates.
4-71. Energy Pulse Output Meter Constant and Pull up
A value can be set which specifies the effective meter constant of the Pulse Out
connector. Whenever an Energy test is active, this output is a pulse stream representing
the total power and energy of the active V/I outputs of all 6100B in the system.
A user-selectable internal pull-up is provided for the Energy Pulse Output. The Use
Internal Pull-up check box selects and deselects this pull-up. The pull-up should
remain deselected (not checked) unless the device connected to the Energy Pulse Output
does not provide a pull-up.
4-72. Conduct the Test
Push to accept the newly defined values, or to cancel all changes.
Pushing starts the test. At this point, the voltage and current source main output
terminals become active. The user cannot leave () the Energy screen while the test is
active. To abort the test, press the key.
During the test, the Energy screen will display rows of numbers corresponding to the user
channel configuration. Pulse rate and total pulses are displayed, either as power and
energy or as frequency and count depending on the Display Units setting. The
accumulated total is compared with the specified reference source and an error or
registration percentage is displayed. These display parameters can be changed “on the
fly” by pressing the corresponding softkey to activate the list box and changing the value
with the cursors. Time elapsed and time remaining (where known) for the test is also
displayed. Time remaining may be an estimate for some mode combinations.
4-73. Test Modes
Under normal operating conditions, all 6100B main outputs are turned off at the end of a
test. If the MUT or reference meters are using the 6100B as a power source, they may
lose their configuration if the voltage is removed from them between tests. If Maintain
Voltage Signal On Completion is selected in Counted/Timed, Gated or Packet
mode, the Current output(s) will turn off, but the Voltage output(s) will not.
XW Warning
High voltage will be present on the voltage output terminals
after the test has completed if the “Maintain Voltage Signal On
Completion” option is selected. Use caution when working
under these conditions.
The Abort Test softkey stops an active test sequence. If Maintain Voltage Signal on
