4.5.5 Length Configuration Commands and Queries
The length configuration commands and queries control the zero offset and
measured span settings for the Model 187. For more information regarding
the length configurations, see paragraph 3.1.3 on page 14. It is important
to limit the zero offset and measured span settings so as to only measure
the span between the reference sensors.
Attempting to set or query for the length settings in the percent remote
units will generate an error. The selected remote units must be inches or
centimeters.
W
CONFigure:LENgth:ZERO < zero_offset >
Configures the “zero point”, or the zero offset from the bottom of the sensor
which will function as the “zero level”. The argument must be in the
selected remote units.
W
LENgth:ZERO?
Returns the “zero point” or zero offset in the selected remote units.
