Introduction 1

Maintenance

Before using the instrument, read and follow the following maintenance instructions:

•Do not leave the instrument in direct sunlight or in a closed vehicle for prolonged periods. Overheating the instrument may reduce its efficiency.

•If the Nivo series instrument has been used in wet conditions, immediately wipe off any moisture and dry the instrument completely before returning the instrument to the carrying case. The instrument contains sensitive electronic assemblies which have been well protected against dust and moisture. However, if dust or moisture gets into the instrument, severe damage could result.

•Sudden changes in temperature may cloud the lenses and drastically reduce the measurable distance, or cause an electrical system failure. If there has been a sudden change in temperature, leave the instrument in a closed carrying case in a warm location until the temperature of the instrument returns to room temperature.

•Do not store the Nivo series instrument in hot or humid locations. In particular, you must store the battery pack in a dry location at a temperature of less than 30 °C (86 °F). High temperature or excessive humidity can cause mold to grow on the lenses. It can also cause the electronic assemblies to deteriorate, and so lead to instrument failure.

•Store the battery pack with the battery discharged.

•When storing the instrument in areas subject to extremely low temperatures, leave the carrying case open.

•When adjusting the leveling screws, stay as close as possible to the center of each screw’s range. The center is indicated by a line on the screw.

•If the tribrach will not be used for an extended period, lock down the tribrach clamp knob and tighten its safety screw.

•Do not use organic solvents (such as ether or paint thinner) to clean the non-metallic parts of the instrument (such as the keyboard) or the painted or printed surfaces. Doing so could result in discoloration of the surface, or in peeling of printed characters. Clean these parts only with a soft cloth or a tissue, lightly moistened with water or a mild detergent.

•To clean the optical lenses, lightly wipe them with a soft cloth or a lens tissue that is moistened with alcohol.

•The reticle plate cover has been correctly mounted. Do not release it or subject it to excessive force to make it watertight.

•Before attaching the battery pack, check that the contact surfaces on the battery and instrument are clean.

•Securely press the cap that covers the data

output/external power input connector terminal.

The instrument is not watertight if the cap is not Reticle plate cover attached securely, or when the data output/external

power input connector is used.

•The carrying case is designed to be watertight, but you should not leave it exposed to rain for an extended period. If exposure to rain is unavoidable, make sure that the carrying case is placed with the Nikon nameplate facing upward.

•The battery pack contains a Lithium-ion battery. When disposing of the battery pack, follow the laws or rules of your municipal waste system.

•The instrument can be damaged by static electricity from the human body discharged through the data output/external power input connector. Before handling the instrument, touch any other conductive material once to remove static electricity.

•Be careful not to pinch your finger between the telescope and trunnion of the instrument.

Unpacking and Packing the Instrument

Note – Handle the Nivo series instrument gently to protect it from shocks and excessive vibration.

Unpacking

To unpack the instrument, grip the carrying handle and gently remove the instrument from the carrying case.

Packing

To pack the instrument back into the carrying case, please refer to the figure on the right.

Charging the Battery Pack

Before charging the battery pack, read the warnings (also listed in the Safety section at the front of this manual) and the following notes.

C C

2 Preparation

Applying Power

•Plug in the charger to the supplied AC adapter to turn the unit on. The power input must be 5 V with at least 4 A of current capability. Each battery may take up to 2 A while charging.

Charging a battery

•Simply slide a battery into either battery slot to begin charging. The adjacent charge indicator will illuminate yellow when charging is in progress. The charge indicator will change to green when charging is complete.

•Charger slots are completely independent so a battery may be inserted regardless of the state of the other battery slot.

•Charging may take 2-4 hours if the battery was normally discharged.

•Charging may take up to 5 hours with a completely drained battery which has been stored for several months without use.

•By design Li-Ion batteries should not be charged above 40 °C-45 °C so a blinking charge light may mean the batteries are too hot for charging. Charging will resume after the batteries cool down. The charging time will be longer due to the batteries cool down when charging batteries above 40 °C-45 °C.

Preparation 2

•If the charge indicator(s) are blinking and the batteries feel cool, it may indicate a problem with the battery or the charger. If the charge light is still blinking after trying several batteries which are not warm, there is a problem with the unit or the batteries themselves.

Conditioning / calibrating a battery

•Battery calibration is necessary about once every 6 months or more often if desired. Calibration insures the reported battery charge remaining is accurate.

•Hold down the calibration button on the unit and then insert a battery while holding the calibration button to begin a battery calibration. Only the battery which was inserted while the button was depressed will begin calibration.

During a battery calibration the battery will be charged, discharged completely, and then recharged before finishing. Calibration should complete in roughly 17 hours and the charger vents should not be covered during a calibration cycle.

•The blue calibration indicator light(s) will blink slowly (on 1.5 sec, off 2 sec) while a calibration is in progress and the charge light(s) may be on or off during the calibration cycle.

•When a calibration cycle is completed, the calibration light will stop blinking remain on until the corresponding battery is removed.

•The bottom case temperature may continue to climb up to approximately 43 °C before temperature regulation is enabled to keep the case from getting warmer. As the battery voltage drops, the case will cool down and the automatic temperature limiting will no longer be necessary which minimizes the time it takes to discharge a battery.

•If the case temperature continues to get too hot internally even after temperature regulation is enabled, there is a secondary failsafe which will abort the calibration completely. If an abort occurs, the calibration light(s) will blink rapidly and battery charging will be re-enabled.

3.Align the laser pointer to the station point. To do this, turn the leveling screws until the laser pointer is over the station point.

4.While supporting the tripod head with one hand, loosen the tripod leg clamps and adjust the lengths or the legs until the air bubble is the center of the circular level.

5.Tighten the tripod leg clamps.

6.Use the electronic level to level the instrument. For detailed instructions, see Leveling, page 15.

7.Check the laser pointer is over the station point.

8.If the station point is off center, do one of the following:

–If the station point is slightly off center, loosen the tripod mounting screw and then center the instrument on the tripod. Use only direct movement to center the instrument. Do not rotate it.

–When the instrument is centered, tighten the mounting screw.

–If the displacement of the station point is major, repeat this procedure from Step 2

Preparation 2

Centering using a plumb bob

1.Set up the instrument on the tripod. For detailed instructions, see Setting Up the Tripod, page 13.

2.Hang the plumb line on the hook of the tripod mounting screw.

3.Adjust the length of the plumb line so that the tip of the plumb bob is at the height of the station point.

4.Loosen the tripod mounting screw slightly.

5.Using both hands to support the outer side of the tribrach, carefully slide the instrument about on the tripod head until the tip of the plumb bob is positioned over the exact center of the station point.

Note – To confirm that the instrument is precisely aligned, check its position from two directions at right angles to each other.

Leveling

When you level the instrument, you make the vertical axis of the instrument exactly vertical. To level the instrument, use the electronic level. In the leveling work, always set the instrument in face 1 direction (please refer to the Fig.1.1 in page 3).

Center crosshairs

If the target image does not move, there is no parallax.

d.If the target image does move, rotate the telescope focusing ring. Then repeat from Step c.

3.Rotate the tangent screw:

– The final turn of the tangent screw should be in a clockwise directions, to align the target accurately on the center crosshairs.

Preparation 2

Setting the Measurement Mode and Preparing the Target

The Nivo series has two measurement modes: Prism mode (Prism) and Reflectorless mode (N-Prism). These modes can be changed at any time by holding down the [MSR1] or [MSR2] key for one second. For more information, see Measurement settings, page 48.

To set the measurement mode depending on the target you want to measure, see the following table.

In some cases, you can measure another target that is not appropriate to the set measurement mode.

Note – The Nivo series is Laser Class 1 in the measurement function, and Laser Class 2 in the Laser pointer function.

Don’t sight the Prism when the Laser Pointer is on.

Measurement with a prism

Do not use a prism with scratches, a dirty surface, or a chipped center. Prisms with thin edges are recommended.

As the Nivo series is extremely sensitive, multiple reflections on the prism surface can sometimes cause a significant loss in accuracy.

To maintain the accuracy of your measurements:

2 Preparation

•When measuring a short distance, incline the prism slightly so that the EDM can ignore unnecessary reflections on the prism surface, as shown below.

Hold the prism securely in place and do not move while taking measurements.

In Prism mode, in order to avoid false measurements on objects other than the prism or reflector-sheet, targets that are less reflective than the prism or reflector sheet are not measured. Even if you start a measurement, measured values are not displayed. To measure less reflective objects, use the N-prism (reflectorless) mode

Measurement in Reflectorless mode

The intensity of the reflection from the target determines the distance the Nivo series can measure in this 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.

The following table describes some examples of targets and approximate measureable distances.

Measurable distances may be shorter or measurement intervals may be longer in the following cases:

•the angle of the laser against the target is small

•the surface of the target is wet

In direct sunlight, the measurable distance may be shorter. 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.

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.

Preparation 2

Preparing the Reflector Sheet

The reflector sheet can be used for measurements in Prism mode. Assemble the reflector sheet as shown below.

Reflector sheet

Mini prism adapter

Setting Up the Prism Reflector

1.Assemble the prism reflector as shown below.

Height adjustment adapter is not used.

Tribrach adapter 15

Tripod

2.Adjust the height of the tribrach adaptor (see page 21).

3.If necessary, change the direction of the prism (see page 21).

4.Set the prism constant (see page 21).

5.If you are using a single prism holder, set the position of the target plate (see page 22).

Detailed instructions for Step 2 through Step 5 are provided on the following pages.

Note – Nivo series must be used with the Tribrach W30 or W30b.

Preparation 2

Adjusting the height of the tribrach adapter

The tribrach adapter has a height adjustment adapter. To use the prism reflector with a Nivo series instrument, remove the height adjustment adapter as shown in the Figure below.

The height adjustment adapter will be used with other Nikon Total Stations.

Changing the direction of the prism

The prism mounted on the tribrach adapter can be rotated to face in any direction.

Setting the prism constant

Note – The prism constant of a Nikon prism is always 0, whether it is attached to a single prism holder or a triple prism holder.

If your prism constant is not 0 mm, then directly enter the prism constant value in the Const field. For example, if your prism constant is 30 mm, enter 30mm in the Const field on the instrument.

Setting the position of the target plate

If using a single prism, make sure that the target plate is aligned with the tribrach adapter and the prism.

To set the position of the target plate:

1.Use the two set screws supplied to attach the target plate to the single prism holder.

2.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.
