5-86. Warm-up Sequence Tree
The warm-up test sequence can be used to allow the MUT and reference sources to settle.
A warm-up sequence can be configured in any operating mode, but will only have an effect
when the operating mode is “TCOunt”. The warm-up test-sequence parameters specify the
initial actions that will occur on sending “OUTPut ON”. The test sequence will then be
executed (see 5-89).
The source of pulses to count can be specified, as well as whether to count for a specific
time period or counter value. The option to let the 6100 calculate the period (from energy) is
also available.
It should also be noted (when “TCOunt” is selected) that there is always a settling period of
approximately 1 Second, whether or not a warm-up period has been defined.
5-87. Warm-up Duration
ENERgy:WUP:DURation(?) {SEConds |MINutes |HOURs | PPERiods | WH | KWH |
MWH},<dnpd>
This command specifies the duration of the warm-up sequence as a period of time, a counter
value (in terms of pulse periods), or a period defined in terms of energy.
SEConds As a time delay in seconds.
MINutes As a time delay in minutes.
HOURs As a time delay in hours.
PPERiods As pulse periods.
WH As accumulated energy.
KWH As accumulated energy.
MWH As accumulated energy.
The following are depreciated parameters from version I of the energy option:
COUNts As pulse counts.
ENERgy As accumulated energy.
Note: When energy is used (WH, KWH, MWH), the actual limits applied will be
determined by the meter constant selected for the pulse source.
5-88. Warm-up Pulse Source
ENERgy:WUP:PSOurce(?) { CH1|CH2|CH3|CH4|CH5|CH6|
SUM456|MEAN456|MEAN56|EMUT|MAIN }
This command specifies the pulse source to use when determining the warm-up sequence-
completion criteria.
The actual sources available will be determined by the active MUT source and reference
source selection.
Note: If one of the source parameters has been changed after using this command a valid
default will be set (typically “CH1” or “MAIN”); so it is recommend that the
“MUT:WUP:PSOurce” command is sent AFTER any “MUT:SOURce” or
“REFerence:SOURce” commands, to prevent unexpected side effects.
