Nikon total station npl 352 manual

To measure less reflective objects, use the N-prism reflectorless mode. Measurement in Reflectorless mode The color and condition of the target surface also affect the measurable distance, even if the targeted objects are the same. Some less-reflective targets may not be measured. In this case, try to throw a shadow on the target.

Targets with completely flat surfaces, such as mirrors, cannot be measured unless the beam and the target are perpendicular to each other. Sighting a prism in Reflectorless mode may cause an excessive signal error.

In the Reflectorless mode, the beam passing area is shown by a circle in crosshairs on the Beam passing area telescope reticle. If the target is smaller than the circle and there is something highly reflective in the background, the measured data may be affected by these adverse conditions. When an obstacle momentarily passes through the beam between the instrument and the target for example, passing cars on the road , the false data short distance is deleted automatically.

However, if the amount of reflection is almost the same and the difference in distances between the correct and the false data is less than two meters, it may cause an error in measurements. Make sure there are no obstacles between the instrument and the target when taking measurents. When you need to take measurements across a road or a place where vehicles or other objects are frequently moving, take several measurements to a target for the best result. Assemble the reflector sheet as shown in Figure 2.

Assemble the prism reflector as shown in Figure 2. Adjust the height of the tribrach adaptor see page If necessary, change the direction of the prism see page Set the prism constant see page Set the position of the target plate see page Detailed instructions for Step 2 through Step 5 are provided on the following pages.

To use the prism reflector with a NPL series instrument, use the lower height setting. To adjust the height of the tribrach adapter: 1. Remove the height adjustment screw from the tribrach adapter. Slide the tribrach adapter up or down the prism holder mount until the height adjustment screw holes on the prism holder mount and on the tribrach adapter are aligned.

Replace and tighten the adjustment screw. Prism holder mount Height adjustment screw Changing the direction of the prism To change the direction of the prism: 1. Release the rotation clamp. To do this, turn the clamp lever counterclockwise. Turn the upper plate of the tribrach adapter Clamp until the prism is facing in the required direction. Clamp lever 3. Fasten the rotation clamp. To do this, turn the clamp lever clockwise. Unclamp Setting the prism constant Attach the prism to the single prism holder.

Set the prism constant. For more information, see Measurement settings, page If your prism constant is not 0mm, then directly enter the prism constant value in the Const field. For example, if your prism constant is 30mm, enter 30mm in the Const field on the instrument. B Tip — When using a prism at a short distance, set the prism at a slight angle to the sighting axis, rather than completely square.

Setting the position of the target plate To set the position of the target plate: 1. Use the two set screws supplied to attach Center on axis the target plate to the single prism holder. Move the target plate within the screw holes until the apex of the wedge pattern is aligned with the vertical axis of the prism and the tribrach adapter. By averaging the Face-1 and Face-2 measurement values, you can cancel out most constant mechanical errors.

Some errors, such as vertical axis error, cannot be cancelled out by averaging Face-1 and Face-2 measurements. A Face-2 measurement is made with the vertical circle positioned to the right of the telescope eyepiece. See Figure 2. Face-1 Face-2 Figure 2. To turn on the instrument, press [PWR].
