Safety Introduction For your safety, read this instruction manual carefully and thoroughly before using the Total Station Nivo series. Although Nikon products are designed for maximum safety, using them incorrectly or disregarding the instructions can cause personal injury or property damage. You should also read the documentation for any other equipment that you use with a Nivo series instrument. Note – Always keep the manual near the instrument for easy reference.
Safety C C C C C C WARNING – Do not cover the battery charger and AC adapter while the battery pack is being recharged. The charger must be able to dissipate heat adequately. Coverings such as blankets or clothing can cause the charger to overheat. WARNING – Avoid recharging the battery pack in humid or dusty places, in direct sunlight, or near heat sources. Do not recharge the battery pack when it is wet.
Safety C C C C C CAUTION – After mounting the instrument on the tripod, securely fasten the thumb screws on the tripod legs. If the thumb screws are not securely fastened, the tripod may collapse, causing personal injury or instrument damage. CAUTION – After mounting the instrument on the tripod, securely fasten the clamp screw on the tripod. If the clamp screw is not securely fastened, the instrument may fall off the tripod, causing personal injury or instrument damage.
Safety C WARNING – Charge and use the rechargeable Lithium-ion battery only in strict accordance with the instructions. Charging or using the battery in unauthorized equipment can cause an explosion or fire, and can result in personal injury and/or equipment damage. To prevent injury or damage: – Do not charge or use the battery if it appears to be damaged or leaking. – Charge the Lithium-ion battery only in a product that is specified to charge it.
Safety C C WARNING – When the laser product is not used, it should be stored in a location where unauthorized personnel cannot gain access. WARNING – Do NOT turn the class 3R laser beam to mirror like specular surfaces; for instance, prisms, metal surfaces or windows, even unintentionally. Special precautions should be taken to ensure eliminating such situations.

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.
1 6 Introduction • 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 attached securely, or when the data output/external power input connector is used.

2 Preparation 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.
Preparation C C C C C C C C 2 WARNING – Charge and use the rechargeable Lithium-ion battery only in strict accordance with the instructions. Charging or using the battery in unauthorized equipment can cause an explosion or fire, and can result in personal injury and/or equipment damage. To prevent injury or damage: – Do not charge or use the battery if it appears to be damaged or leaking. – Charge the Lithium-ion battery only in a product that is specified to charge it.
2 Preparation Power jack Charge indicator 0 This will read 5V, 4A Calibration indicator 0 Case “Top” edge Calibration button Calibration indicator 1 Charge indicator 1 Battery Slot 0 Battery Slot 1 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 10 • Simply slide a battery into either battery slot to begin charging.
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.
2 Preparation Detaching and Re-Attaching the Battery Pack Detaching the battery pack C CAUTION – Avoid touching the contacts on the battery pack. 1. If the instrument is turned on, press [PWR] to turn it off. 2. Turn the battery box release knob counterclockwise, open the battery box cover and remove the battery pack from the battery box. Inserting the battery pack Before inserting the battery pack, clear any dust or other foreign particles from the battery contacts. 2 3 1 C 12 1.
Preparation 2 Setting Up the Tripod C CAUTION – The tops of the tripod ferrules are very sharp. When handling or carrying the tripod, take care to avoid injuring yourself on the ferrules. 1. Open the tripod legs enough to for the instrument to be stable. 2. Locate the tripod directly over the station point. To check the tripod’s position, look through the center hole in the tripod head. 3. Firmly press the tripod ferrules into the ground. 4. Level the top surface of the tripod head. 5.
2 Preparation 5. Use the electronic level to level the instrument. For detailed instructions, see Leveling, page 15. 6. Look through the optical plummet to check that the image of the station point is still in the center of the reticle mark. 7. 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.
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.
2 Preparation Sighting When you sight the instrument, you aim the telescope at the target, bring the target image into focus, and align the image with the center crosshairs of the reticle. Center crosshairs To sight the instrument: 1. Adjust the diopter: a. C Aim the telescope at a blank area, such as the sky or a piece of paper. WARNING – Never look at the sun through the telescope. If you do, you may damage or lose your eyesight. b. 2.
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. To set the measurement mode depending on the target you want to measure, see the following table.
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.
Preparation 2 Setting Up the Prism Reflector 1. Assemble the prism reflector as shown below. Target plate for single prism Target pole Height adjustment adapter is not used. Tribrach adapter 15 Prism C Tribrach W30/W30b Tiltable single prism holder Triple prism holder Tripod 2. Adjust the height of the tribrach adaptor (see page 20). 3. If necessary, change the direction of the prism (see page 20). 4.
2 Preparation 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. Height adjustment adapter Height adjustment adapter clamp screw Changing the direction of the prism The prism mounted on the tribrach adapter can be rotated to face in any direction.
