General Handling Precautions

Before starting work or operation, be sure to check that the instrument is functioning correctly with normal performance.

Do not submerge the instrument into water.

The instrument can not be submerged underwater.

The instrument is designed based on the International Standard IP66, therefore it is protected from the normal rainfall.

Setting the instrument on a tripod

When mounting the instrument on a tripod, use a wooden tripod when possible. The vibrations that may occur when using a metallic tripod can effect the measuring precision.

Installing the tribrach

If the tribrach is installed incorrectly , the measuring precision could be effected. Occasionally check the adjusting screws on the tribrach. Make sure the base fixing lever is locked and the base fixing screws are tightened.

Guarding the instrument against shocks

When transporting the instrument, provide some protection to minimize risk of shocks. Heavy shocks may cause the measurement to be faulty.

Carrying the instrument

Always carry the instrument by its handgrip.

Exposing the instrument to extreme heat.

Do not leave the instrument in extreme heat for longer than necessary. It could adversely affect its performance.

Sudden changes of temperature

Any sudden change of temperature to the instrument or prism may result in a reduction of measuring distance range, i.e when taking the instrument out from a heated vehicle. Let instrument acclimate itself to ambient temperature.

Battery level check

Confirm battery level remaining before operating.

Taking the battery out

It is recommended not to take the battery out during the power is on. All the data stored is possible gone at that time. So please do your assembling or taking the battery out after the power is off.

Noise from the inside of instrument

When EDM turns on, the sound of motors from inside the instrument body may be heard. This is normal and does not effect operation of the instrument.

2 PREPARATION FOR MEASUREMENT

2.2 Setting Instrument Up For Measurement

Mount the instrument to the tripod. Level and center the instrument precisely to insure the best performance. Use tripods with a tripod screw of 5/8 in. diameter and 11 threads per inch, such as the Type E TOPCON wideframe wooden tripod.

Reference: Leveling and Centering the Instrument

1. Setting up the Tripod

First, extend the extension legs to suitable lengths and tighten the screws on their midsections.

2. Attaching the Instrument on the Tripod Head

Place the instrument carefully on the tripod head and slide the instrument by loosening the tripod screw. If the plumb bob is positioned right over the center of the point, slightly tighten the tripod screw.

3. Roughly Leveling the Instrument by Using the Circular Level

1Turn the leveling screws A and B to move the bubble in the circular level. The bubble is now located on a line perpendicular to a line running through the centers of the two leveling screws being adjusted.

Leveling screw C

	Leveling	Leveling screw B
	screw A

2Turn the leveling screw C to bring the bubble to the center of the circular level.

4. Centering by Using the Plate Level

1Rotate the instrument horizontally by using the Horizontal motion/clamp screw and place the plate level parallel with the line connecting leveling screws A and B, and then bring the bubble to the center of the plate level by turning leveling screws A and B.

2Rotate the instrument 90° (100gon) around its vertical axis and turn the remaining leveling screw or C to center the bubble once more.

Leveling screw C

90°

3Repeat the procedures 1 and 2 for each 90° (100gon) rotation of the instrument and check whether the bubble is correctly centered for all four points.

5.Centering by Using the Optical Plummet Telescope

Adjust the eyepiece of the optical plummet telescope to your eyesight.

Slide the instrument by loosening the tripod screw, place the point on the center mark, and then tighten the tripod screw. Sliding the instrument carefully not to rotate that allows you to get the least dislocation of the bubble.

6. Completely Leveling the Instrument

Leveling the instrument precisely in a similar way to 4. Rotate the instrument and check to see that the bubble is in the center of the plate level regardless of telescope direction, then tighten the tripod screw hard.

Battery power remaining display

Measurement is possible.

The power is poor. The battery should be recharged or replaced.

Blinking

<Battery empty>	Measurement is impossible.
Other displays disappear.	Need to recharge or replace
	the battery.

Note: 1 The battery operating time will vary depending on the environmental conditions such as ambient temperature, charging time, the number of times of charging and discharging etc. It is recommended for safety to charge the battery beforehand or to prepare spare full charged batteries.

2For general usage of the battery, see Chapter 14 “POWER SOURCE AND CHARGING” .

3The battery power remaining display shows the power level regarding to the measurement mode now operating.

The safety condition indicated by the battery power remaining display in the angle measurement mode does not necessarily assure the battery’s ability to be used in the distance measurement mode.

It may happen that the mode change from the angle mode to the distance mode will stop the operation because of insufficient battery power for the distance mode which consumes more power than angle mode.

2 PREPARATION FOR MEASUREMENT

2.5 Vertical and Horizontal Angle Tilt Correction

(GPT-2009 has vertical angle tilt correction only.)

When the tilt sensors are activated, automatic correction of vertical and horizontal angle for mislevelment is displayed.

To ensure a precise angle measurement, tilt sensors must be turned on. The display can also be used to fine level the instrument. If the (TILT OVER) display appears the instrument is out of automatic compensation range and must be leveled manually.

	Horizontal	Trunnion axis

●GPT-2000 compensates both the vertical angle and the horizontal angle readings due to inclination of the standing axis in the X and Y directions .

●For more information about dual axis compensation, refer to APPENDIX 1 “Dual Axis Compensation”.

When the instrument is out of compensation. (TILT OVER)

2.7Point Guide (Only for Point Guide type)

Fast and simple to use, the Point Guide feature is useful when doing stake out work. The LED’s for the

Point Guide System on the instrument telescope assist the rod person to get on-line. When using the Point Guide System, the battery life will be approximately 8 hours at +20 °C (+68 °F).

Turning the Point Guide ON and Operation:

Press the [MENU] key to get the menu screen and press the

Instrument

[MENU] key again. Point Guide LED’s will be turned ON. Looking at the objective lens of the telescope, the right LED will blink and the left LED will stay lit.

The Point Guide should be used within a distance of 100 meters (328 feet). The quality of its results will depend on the weather conditions and the user’s eyesight.

The goal of the rod person is to look at both LED’s on the instrument and move the prism on-line until both LED’s are equally bright.

●If the solid LED is brighter, move right.

●If the blinking LED is brighter, move left.

Illuminate Blink

Prism

Once you have determined that both of the LED's are equally bright, you are on-line with the instrument.

Turning the Point Guide OFF:

To turn OFF the Point Guide System, press the [MENU] key again in menu screen.

The point guide function can be available while executing Layout mode. See 8.2 “Executing a Layout”.

Reference : How to Collimate

1Point the telescope toward the light. Turn the diopter ring and adjust the diopter so that the cross hairs are clearly observed.

(Turn the diopter ring toward you first and then backward to focus.)

2Aim the target at the peak of the triangle mark of the sighting collimator. Allow a certain space between the sighting collimator and yourself for collimating.

3Focus the target with the focusing knob.

*If parallax is created between the cross
hairs and the target when viewing			Focusing knob
