[. . . ] WARNING Items indicated by this display are precautions which if ignored could result in death or serious injury. CAUTION Items indicated by this display are precautions which if ignored may result injury or material damage. Here "injury" refers to injuries such as cuts, burns or electric shock the treatment of which will not likely require hospitalization or long-term attention. "Material damage" refers to the damage to facilities, buildings, acquired data, etc. [. . . ] · Press the battery box to the leg by inserting the guide pin to the guide groove. · Confirm the correct work by pressing the power switch. This instrument can operate using 1. 2V AA rechargeable batteries. · The four (4) batteries, in a battery box, should be of the same type. Do not use batteries, in a battery box, which have different remaining capacities. · When a battery box or batteries are wet, wipe off the moisture immediately and dry completely. · When a battery box is removed from the unit, power must be off. If the battery box is removed with power on, it will cause trouble. 13 2. Key Operations and Display 2. 1 Display Vertical angle V=Zenith 0°, V%=Slope(VH=Horizontal 0°, Vc=Compass) Horizontal angle Battery indicator: (HR=right rotation horizontal angle, HL=left rotation horizontal angle) 2. 2 Keyboard [V/%] key [R/L] key [HOLD] key [0SET] key [ (Switches the display of vertical angle) (Set the horizontal angle right and left rotation alternately) (Pressing twice holds the horizontal angle shown on the display) (Pressing twice resets the horizontal angle to 0°, 00', 00") ] Illumination key (Illuminate LCD panel and the telescope reticle) (Turns the power on and off alternately) [ON/OFF] key 14 2. 3 Function of each key 2. 3. 1 Power [ON/OFF] key 1 <Power ON and set the vertical angle 0 point> Pressing the ON/OFF key turns on the power supply and the message "0 SET" is displayed. After the "0 SET" of vertical angle is performed, the Horizontal and Vertical angle are displayed and the instrument enters into the angle measurement mode. 2 <Setting vertical angle 0 point> Set the vertical angle 0 point by turning the telescope upward or downward when the instrument is at the "normal" position (Vertical circle at left. ) <Power OFF> To turn the power supply off, press the ON/OFF key for more than 1 second ("OFF" will display) and then release it. Power turns OFF. 3 15 2. 3. 2 [V/%] key Pressing the V/% key will change the Vertical angle display to V%(slope). (At the shipping, it is set at Zenith 0°) By special key operation, horizontal 0° (VH) and Compass (Vc) can be set. (Factory default is Zenith 0°) (Refer to 3. 1 Setting of vertical angle. ) 16 The error "OVER RANGE" is displayed when the telescope exceeds 45°(100%) in the V% display mode. 17 2. 3. 3 [HOLD] key 1 Press the [HOLD] key twice in succession to hold the displayed horizontal angle and retain it. 5 Accurately align the reticule with the object, using each tangent screw. Collimator Focusing ring object Telescope eyepiece Horizontal clamp screw Horizontal tangent screw · In procedure 4 , focus on the object correctly so that the reticule will not move in relationship to the object when you move your eye slightly left and right, while looking through the eyepiece. · Two screws of the collimator are fixed and adjusted at the distributor or the manufacturer. Measurement 5. 1 Horizontal angle measurement (right) 1 2 3 4 5 Level the instrument, and after power on set the vertical angle 0 point. Sight the first object using the horizontal clamp and tangent screw as well as the telescope clamp and tangent screw. Press [0SET] twice to set the horizontal angle to 0°, 00', 00" Sight the second object using the horizontal clamp and tangent screw as well as the telescope clamp and tangent screw. Read the displayed value (). First Object: Zero Setting (0 °00' 00") Second Object (34 °47' 20") Horizontal Angle () = 34 °47' 20" First object Second object 34 5. 2 Horizontal angle measurement (left) 1 2 3 Level the instrument, and after the power on set the vertical angle 0 point. Sight the first object using the horizontal clamp and tangent screw as well as screw as well as the telescope clamp and tangent screw. Press the [R/L] key to switch the horizontal angle display to counterclockwise reading (HL). Subsequent operation will be done as in [5. 1 Horizontal angle measurement (right), but the order of collimation is reversed. To switch the mode back to "right" press the [R/L] key again. , · If the power turns off during the counterclockwise mode, the display returns to a clockwise horizontal angle display when power is turned on. 35 5. 3 Vertical angle measurement Level the instrument, turn the power on and set the vertical angle 0 point. Sight the object A using the horizontal clamp and tangent screws as well as the telescope clamp and tangent screws. [. . . ] 3 No adjustment is necessary if point A moves along the vertical line of the reticule. If the point A does not move along the vertical line of the reticule, it needs adjustment - Consult with your dealer. Vertical line Line of sight axis A' 40 6. 5 Perpendicularity of line of sight to horizontal axis Inspection 1 Set an object (point A) at a distance of 30 to 50m away from the instrument and sight it through the telescope. 2 Loosen the telescope clamp screw and reverse the telescope around the horizontal axis. Mark a point set on the line of sight at about the same distance to the object point A, and call it point B. [. . . ]
