Flat mascara is one of the tools on the scope of the survey and mapping which is used to measure the height difference between one point to the other points, and can also measure the distance (called an optical distance = distance indirectly)
Parts Sipat Tool Flat:
- Kiap Down (Trivet Stage): is an airstrip that rested on the head statip which have screw holes to lock that plane blend strongly with statip
- Flatness adjuster screws: are three screws to adjust the bubble tube so that its position in the midst, so that the reference line parallel to the horizontal plane
- Top Kiap (tribrach) is the main foundation where the founding peak three screws setter. Besides, also as bearers of the upper part of the fuselage.
- Binoculars, in which there are objective lens (in advance) and eyepiece (behind). Also there is the crosshairs, the imaginary line connecting the point of intersection between the cross thread the diaphragm with the midpoint of the objective lens, forwarded to the target / target. These binoculars can only be played on the axis of unity.
- Nivo Tubes / box is used as a guideline nivo tuning bidiknya aircraft to the line parallel to the line direction nivo. Nivo is placed into one with binoculars.
- Objective lens, is a lens on a telescope that is located on the front, and the greatest
- Ocular lens, is a lens on a telescope that is located on the back that is smaller than the objective lens.
- Ring / circle diaphragm regulator, is a tool used to set the image / shadow apparent targets in binoculars.
Basically Flat Sipat tools can be divided into three types / kinds, including:
a. Sipat tool Flat Type Stump
Flat Sipat tool types Stump is a kind of tool construction Sipat Datar solid and very simple.
Figure 43 Tool Sipat Flat Type Stump (Dumpy Level)
The characteristics of Type Flat Sipat tool Stump is: The crosshairs have been made perpendicular to the axis of unity by the manufacturer, so that if the bubble has been located in the middle, this means:
– Nivo horizontal direction lines
– Because the line nivo direction parallel to the crosshairs and the crosshairs perpendicular to the axis of unity, then the line nivo direction perpendicular to the axis of unity (sb. I).
b. Flat Sipat tool type Pinch
Is a kind of tool Sipat Datar, the top and bottom are separated by a hinge or joint, so that the glasses can be leveraged up or down (up / down) little by little, so that the position of the crosshairs perpendicular to the axis of unity, as shown in the picture 2.
Figure 44 Tool Sipat Flat Leverage Type
Parts of Sipat Tool Pinch Flat Type:
- Kiap Down (Trivet Stage): is an airstrip that rested on the head as to the type of muscular statip
- Flatness adjuster screws: are three screws to adjust the bubble tube / box, so that the unity axis perpendicular to the plane of reference nivo and horizontal cross thread.
- Top Kiap (tribrach) is the locus of nivo box and hinges.
- Binoculars, somewhat different from the type of muscular, because the on / off binoculars are nivo tube (nivo coincidence)
- Nivo Tubes / nivo nivo coincidence is one that is used to guide whether the crosshairs aligned with the reference line nivo.
- Nivo box, is nivo to the guidelines that the axis of unity was perpendicular to the reference plane nivo
- Joints (hinge), for connecting the bottom and top of the fuselage, which through this hinge binoculars can be leveraged up / down, so that bidiknya line parallel to the reference line with the guidelines nivo nivo nivo tube or coincidence.
- Levers screw, used to bring binoculars upwards / downwards, so that the bubble tube / koinsidensi balanced, which means the crosshairs perpendicular to the axis of unity.
