Applications 4 Sample output records through COM port When the Ext.Comm field is set to NIKON: TR PN: PT8 SD:000066626 HA:003856010 VA:008048500 HT:0000061757 (TR PN: point name SD HA VA HT; when ACK is returned, PN is incremented.) When the Ext.Comm field is set to SET: 0006662 0804806 0394324 97 (SD VA HA Chk-SUM) Measuring Offsets Measuring taped offsets 1. To enter the taped offset function, press [1] or select Tape in the Offset menu.
4 Applications You can enter any combination of taped offset distances to specify the point. 4. To go to the recording PT screen, press [ENT] in the last field. The calculated coordinates are shown. 5. Enter a PT (and CD) value. 6. Press [ENT] to record the point. Raw data is also recalculated, based on the taped offset value. Measuring angle offsets 1. To enter the angle offset function, press [2] or select Angle in the Offset menu.
Applications 4 Two-prism pole 1. To enter the two-prism pole function, press [3] or select 2Prism Pole in the Offset menu. 2. Sight the first prism and press [MSR1] or [MSR2]. 3. Sight the second prism and press [MSR1] or [MSR2]. 4. Enter the distance between the second prism and the target point. Alternatively, if you do not need QA information, you can leave the distance between the first and the second prism blank. 5. If you do enter a P1-P2 distance, the QA screen appears.
4 Applications Extending a line by horizontal angle offset 1. To enter the line extension (by HA) function, press [4] or select +Line by HA in the Offset menu. 2. Sight the first prism (or target) and press [MSR1] or [MSR2]. The display moves to the next screen. 3. Sight the second prism (or target) and press [MSR1] or [MSR2]. 4. Sight the alternative place on the same vertical line as the required target point. 5. To calculate the coordinates and the raw data of the target point, press [ENT].
Applications 4 The calculated point (TGT) is stored as a SS record. Measurements to the first and second target (P1 and P2) are stored as comment records (PT1 and PT2). The last record records the angle measurement to the ALT (vertically offset point from the actual target point). Entering a horizontal distance after an angle-only shot This function is useful when the instrument is very close to the point and it is difficult to take a measurement using the EDM. 1.
4 Applications Calculating a corner point 1. To enter the corner point function, press [6] or select Corner in the Offset menu. 2. Take a distance measurement to the first prism (or target) on the wall. Press [MSR1] or [MSR2]. 3. Sight a second point on the same wall with the first point measurement. Press [MSR1] or [MSR2]. 4. Sight the first point on the second wall. Press [MSR1] or [MSR2]. 5. If the two walls are at right angles, press the softkey to calculate the corner point by three points.
Applications 4 Sample records SS, 58, 0.0000, 48.3304, 169.19165, 82.02470, 10:52:37, FLOOR2 CO, PT1, 1.0080, 48.3020,169.19165, 83.58565 CO, PT2, 1.0080, 48.3155,128.54250, 85.42440 CO, O/S MSR:40 0.0000 0.0000 169.20370 87.02340 The calculated corner point is stored as an SS record. The next three or four comment records are measured points. For example: CO, Point name (fixed to PT1, PT2 etc.), HT, SD, HA, VA. Measuring circle offsets 1.
4 Applications The instrument calculates and records the center of the circle. It also calculates the coordinates of the center point and the radius of the circle. 5. To record the point, press [ENT] or the OK softkey.
