*RST, SYSTem:PRESet
These steps also clear
all
readings
in reading memory. (
*RST
and
SYSTem:PREset
additionally reset the lower and upper limits to 0.0.)
To turn off the ‘Limit’ annunciator and clear only the limit-sensing bits (11/12
in the Condition register)
without
clearing reading memory, the following
command is used:
CALCulate[1]:LIMit:CLEar[:IMMediate]
Histograms
The distribution for a given set of counter measurements (
except continuous
totalize and time stamp measurements
) can be represented graphically using
the 53220A/ 53230A histogram feature. The following example (Figure 6-5)
represents the basic format of a counter histogram.
