SPRINTER 100/100M/200/200M
Operation
Backlight
Use the lens hood (optional accessory) to cover the objective when back light disturbs
your work. As a last resort, use your hands to shield the objective from disturbing back-
light.
Darkness
Evenly illuminate the measuring area of the staff with a flashlight or spotlight in darkness.
Measuring at the
bottom of the staff
Measurements slightly below the zero point are possible (negative measured values).
Measuring at the
upper end of the staff
Measurements slightly above the top end of staff (full length) are possible.
Shade
Shaded patterns on the staff normally do not affect the measured results. Extremely dark
shade can have the same effects as an interfering cover has on the field-of-view.
Focus
A slightly unfocussed image does not influence the measuring time and the accuracy.
When large focus errors occur, measurement is stopped.
Measuring through
window panes
Avoid measuring through window panes.
Extension of staff
sections
Staff sections have to be fully extended and properly secured with the aid of locking pin
behind the staff (a click sound can be heard when the locking position is secured), in order
to have accurate and correct measurement.
