The measuring time setting option allows also the modifying of the measuring rate, for example, in order to
restrict the data volume or for synchronization purposes.
Measuring time can only be set as an approximate value, because the underlying principle of measurement
is subject to certain variances that cannot be accounted for:
DT measuring mode > measuring time approximately ST x 240 ms (except ST = 0)
DS measuring mode > measuring time approximately ST x 150 ms (except ST = 0)
Example:
The target distance is 25 m, but the target’s reflectance is not ideal. With a measuring time setting of ST 2,
E15 will be output following measurement. The user must increase the measuring time in this case!
i
One should work in DW or DX mode where stable measuring times are required.

SFx.x.....Display/Set Scale Factor
Standard setting: 1
SF multiplies a calculated distance value with a user-selectable factor for changes in resolution or outputs in
a different unit of measure. The scale factor may also be negative.

Following a change in the scale factor, the settings for digital and/ or analog output and offset must be
matched accordingly!
