raw readings into measurements by applying the calibration
constants. During the post- processing phase, the front panel
“*” annunciator is lit.
The acquisition phase of burst mode can be aborted by
pressing the EXIT key. Then the Model 2001 starts post-
processing on that portion of the reading buffer.
Since burst mode turns off autozero, an autozero refresh is
required once every 24 hours (by changing functions, resolu-
tion, or issuing an autozero bus command).

2. Multiple displays of buffered readings are available when burst data is recalled. (See paragraph 3.5.4.)
measure layer of the trigger model until the requested num-
ber of readings is acquired. To enhance burst acquisition
speed, the front panel is not updated until the raw readings
are being post-processed.
Meter Complete output pulses are sent at the rate of 2kHz
during the acquisition phase. (Note: The last one is not sent
until post-processing is done.)
After the acquisition phase, the unit returns to the idle state
and starts post-processing, which consists of converting the
