(VARS)
The T360 has several-user adjustable software variables, which define certain
operational parameters. Usually, these variables are automatically set by the
instrument’s firmware, but can be manually re-defined using the VARS menu.
Table 4-13 lists all variables that are available within the 818 password protected
level.

questionable. That is the case during warm-up or just after
the instrument returns from one of its calibration modes to
SAMPLE mode. DAS_HOLD_OFF can be disabled entirely
in each DAS channel.
Can be between 0.5
