Yes - Time history storage is enabled.
Hist Period (LOG, SSA)
This setting is used in conjunction
with the “Period Units Setting”
(below). Hist Period sets the number of history period units that
transpire between successive time history samples. These
samples continue either until the instrument is stopped or
runs out of memory. This setting can include any integer
value in the following range:
(0) to (255)
Period Units - (LOG, SSA)
Period Units selects the type of units the instrument uses to
calculate the time which transpires between successive time
history storage operations. To calculate the timer period, the
instrument multiplies the units selected in this setting by the
number set in Hist Period setting (see the previous “Hist
Period” setting and the following example).
