13 Press the [F4](CALC) key. *6)
Standard Deviation will be shown.
Unit : (sec.) or (mGON) or (mMIL)
[F4]
14 Press the [F2](
) key.
Standard Deviations of each coordinate will be
shown.
Unit : (mm) or (inch)
The display will be changed alternately by
pressing [F2](
) or (
) key.
[F2]
15 Press the [F4](NEZ) key.
Coordinate data of the new point will be shown.
[F4]
16 Press the [F3](YES) key. *7)
The new point data will be stored into the
coordinate data le and the value of occupied
coordinate data will change to that of the
calculated NEW POINT.
The display returns to new point menu.
[F3]
*1) Refer to Section 2.6 “How to Enter Alphanumeric characters”.
*2) When there is no need to memorize the new point data, press the [F3](SKP) key.
*3) To enter the known point coordinate data by direct key inputting, press the [F3](NEZ) key.
*4) RESIDUAL ERROR;
dHD (Horizontal distance between two known points) =Measured value – Calculated value
dZ=(Z coordinate of the new point calculated from known point A) – (Z coordinate of the new point
calculated from known point B)
*5) [F1:USE LAST DATA]; RESIDUAL ERROR is calculated with GRID FACTOR already set.
[F2:CALC MEAS.DATA]; RESIDUAL ERROR is calculated without GRID FACTOR already set. In this
case, new GRID FACTOR is calculated from measured data and reset."
To see the GRID FACTOR value, press the [F3](G.F.) key.
*6) In case that the all points are measured by angle measurement only, the following display will be shown.
You can select Z coordinate calculation.
F1(YES) : :N,E,Z coordinates will be calculated with measured angle data.
F2(NO) : :N and E coordinates will be calculated with measured horizontal angle data. Z coordinate
would not be calculated.
(Z coordinate value =0.000m)
When the distance measurement is done even one point, Z coordinate will be calculated as a mean
value of relative distance (vertical distance data).
*7) The display shows ">SET ?" when [F3](SKP) key pressed in step
4. In this case, the new point data is
not stored into the coordinate data le, only the value of occupied coordinate data changes to that of the
calculated NEW POINT.
