How to use the smart adapters

Setup device to adapter

Snap the device on the Twist 360 adapter.

Alignment of vertical laser lines

Turn the device 360° around the plumb point to adjust the vertical line.

Alignment of horizontal laser lines

Turn the adjustment knob of UAL130 to fine adjust the horizonal line to the desired reference level.

Accuracy Check

Check the accuracy of your instrument regularly and particularly before important measuring tasks. Check Levelling lock before checking the accuracy.

Levelling
Checking the accuracy of the levelling

Set the instrument on a tripod half-way between two walls (A+B) that are approx. 5 m apart. Place the lock switch in the "Unlocked" position (see Levelling lock). Direct the instrument at wall A and switch on the instrument. Activate the horizontal laser line or laser point and mark the position of the line or the point on wall (A1). Rotate the instrument by 180° and mark the horizontal laser line or the laser point in exactly the same way on wall (B1).

Then place the instrument at the same elevation as close as possible to wall A and again mark the horizontal laser line or the laser point on wall A (A2). Rotate the instrument by 180° again and mark the laser on wall B (B2). Measure the distances of the marked points A1-A2 and B1-B2. Calculate the difference of the two measurements. |(A1 - A2) - (B1 - B2)| <=2 mm If the difference does not exceed 2 mm, then the instrument is within tolerance.
Should your instrument be outside of the specified tolerance, please contact a local dealer or an authorised Leica Geosystems distributor.

Vertical and horizontal line
Checking the accuracy of the horizontal line

Place the lock switch in the "Unlocked" position (see Levelling lock). Position the instrument approx. 5 m away from the wall. Direct the instrument at the wall and switch on. Activate the laser line and mark the intersection point of laser crosshairs on the wall. Swivel the instrument to the right and then to the left. Observe the vertical deviation of the horizontal line from the marking. If the difference does not exceed 3 mm, then the instrument is within tolerance.

Checking the accuracy of the vertical line

Place the lock switch in the "Unlocked" position (see Levelling lock). As a reference, use a plumbbob and attach it as close as possible to an approx. 3 m high wall. Position the instrument at a distance of approx. 1.5 m from the wall at an elevation of approx. 1.5 m. Direct the instrument at the wall and switch on. Rotate the instrument and align it with the bottom of the plumb line. Now read off the maximum deviation of the laser line from the top of the plumb line. If the difference does not exceed 2 mm, then the instrument is within tolerance.
Should your instrument be outside of the specified tolerance, please contact a local dealer or an authorised Leica Geosystems distributor.

Vertical plumb points
Checking the accuracy of the upper plumb point:

Place the lock switch in the "Unlocked" position (see Levelling lock). Set up the laser on its tripod to wall mount bracket near point A1 at a minimum distance of 1.5 m from point B1. The horizontal laser is aligned in direction 1. Mark the laser points A1 and B1 with a pin.

Checking the accuracy of the lower plumb point:

Rotate the instrument by 180° so that it points in the opposite direction 2 to direction 1. Adjust the instrument so that the laser beam hits point A1 exactly. If point B2 is no further than 2 mm away from point B1, then the instrument is within tolerance.
Should your instrument be outside of the specified tolerance, please contact a local dealer or an authorised Leica Geosystems distributor.

Perpendicularity horizontal points

Place lock switch in "Unlocked" position (see elling lock). Mark a reference point (P1) approx. 5m from the walls and position the lower plumb point exactly on it. Align the cross hair to the left wall and mark the intersection point (a1) approx. on the same hight like P1 to the wall. Shortly after mark the right-hand perpendicular beam (b1) on the front wall.

Then rotate the device exactly 90° clockwise around the plumb point P1 and position the left-hand perpendicular beam to the existing reference point a1. Make sure that the upper plumb point is still exactly on the reference P1. Check afterwards the new reference point b2 with the old reference b1 on the front wall. The deviation between the two points may be max. 3mm. Mark the new position of the right-hand perpendicular beam to the right wall with c1.
Should your instrument be outside of the specified tolerance, please contact a local dealer or an authorised Leica Geosystems distributor.

Afterwards turn the device exactly 180° around the plumb point P1 and position the right-hand perpendicular beam to the existing reference point a1. Make sure that the upper plumb point is still exactly on the reference P1. Then mark the left-hand beam to the right wall and mark it with c2. Finally measure the difference between the former reference point c1 and the new point c2. The deviation may be max. 3mm between these two points.
Should your instrument be outside of the specified tolerance, please contact a local dealer or an authorised Leica Geosystems distributor.

Care

Never immerse the device in water. Wipe off dirt with a damp soft cloth. Never use aggressive cleaning agents or solvents. Treat the instrument with the same care that you would apply to binoculars or a camera. Dropping or violent shaking of the instrument may damage it. Check the instrument for any damage before using it. Check the levelling accuracy of the instrument regularly. To warranty the best precision and visibility please clean the optics of your device regularly. Therefore blow off the dust from the glasses without touching the optics with your fingers. If necessary use a damp soft cloth and a little bit of pure alcohol. To avoid wrong measurements also clean your adapters regularly. This could be done also by the proposed recommendation. Especially the interface between the adapter and device should always be clean to enable easy rotation. To clean the magnetic surface you could use compressed air or modelling clay. If the equipment get wet always dry it (max. 70°C/158°F) before repacking it into the case.
