Menu Screen 5 Searching records You can search for records by their type, point name, code, or by any combination of these values. Searching raw records In the RAW screen, select the Srch softkey to access the raw data search function. • To find a point by name, enter the name in the PT field and press [ENT] twice. You can use the asterisk (*) as a wildcard. For example, when you enter 30* in the PT field, the search matches the points named 300, 301, 302, 3000A2, and 3010.
5 Menu Screen Searching coordinate records In the XYZ screen, select the Srch softkey to access the XYZ data search function. • To find a coordinate by name, enter the point name in the PT field and press [ENT] twice. You can use the asterisk (*) as a wildcard. For example, when you enter 500* in the PT field, the search matches the points named 500, 500-1, 500-A, and 5000. • To search for a record by point type, move to the Type field and use [<] or [>] to change the selected point type.
Menu Screen 5 Entering coordinates 1. In the XYZ screen, select the Input softkey. A new input point screen appears. The PT field defaults to the last recorded PT + 1, but you can change the value shown. 2. Use the numeric keys to enter the coordinates. Press [ENT] or [v] in each field to move to the next field. When you press [ENT] in the CD field, the point is stored as an MP record. After you have recording a point, the next point input screen is shown with the updated default PT.
5 Menu Screen Communication Use the Communication menu to download or upload data. To access it, press [4] or select Comm. on the MENU screen. Downloading coordinate data To change the download settings, press [1] or select Download in the Communication menu. Format NIKON (Fixed) Data RAW Coordinate To display the total number of records that will be downloaded, press [ENT] in the Data field.
Menu Screen 5 Optional Bluetooth function When the optional Bluetooth wireless technology function is installed, a Port selection screen appears when you press the Comm softkey. Uploading coordinate data To upload coordinate data from a computer, press [2] or select Upload XYZ in the Communication menu. The default data format appears. To change the order of data fields, select the Edit softkey. See also Advanced feature: Editing the data order for upload, page 114. Otherwise, press [ENT].
5 Menu Screen If you press [ESC] during data upload, the upload is canceled and the display returns to the Communication menu. Records that were received before you pressed [ESC] are stored in the job. During upload, the system will truncate any code that is longer than 16 characters. If the existing point is a UP, CC, or MP record, and it is not referred to by any station or backsight, it is automatically overwritten by the uploaded point. No error message appears.
Menu Screen 5 1sec-Key Use the 1sec-Key menu to configure the settings for the one-second buttons, [MSR1], [MSR2], and [DSP]. To access it, press [5] or select 1sec-Keys in the MENU screen. [MSR] button settings There are two [MSR] buttons: • To change the settings for the [MSR1] button, press [1] or select MSR1. • To change the settings for the [MSR2] button, press [2] or select MSR2. Each [MSR] button has four settings. In the Const and Track field, use the numeric keys to enter values.
5 Menu Screen Calibration Use the Calibration screen to calibrate the instrument if required. To access the Calibration screen, press [6] or select Calibrat from the MENU screen. See also Adjusting the calibration, page 120. Time Use the Date & Time screen to set the current date and time. 1. Press [7] or select Time on the MENU screen. The Date & Time screen appears. The current date and time settings are displayed. 2. Enter the date in Year-Month-Day format.
CHAPTER 6 Checking and Adjusting In this chapter: Adjusting the electronic level Checking and adjusting the circular level Checking and adjusting the optical/laser plummet Zero point errors of vertical scale and horizontal angle corrections The instrument constant Checking the laser pointer 6 This chapter describes how to check the accuracy of the Focus 4 total station, and if necessary, adjust the required settings.
6 Checking and Adjusting Adjusting the electronic level To adjust the electronic level, Zero point errors of vertical scale and horizontal angle corrections are used. See page 119. Checking and adjusting the circular level Once you have checked and adjusted the electronic level, check the circular level. If the bubble is not in the center of the level, use the adjusting pin to rotate the three adjustment screws of either circular level on the instrument main body or tribrach until the bubble is centered.
Checking and Adjusting 5. 6 If the image or laser pointer is not in the same position, adjust the optical or laser plummet: a. Use the supplied hexagonal wrench to turn the adjustment screws until the image of the X is in Position P. Position P is the center point of the line connecting the X and the center of the reticle mark . b. Repeat from Step 2. For laser plummet adjustment, you must remove a cap. Zero point errors of vertical scale and horizontal angle corrections Checking the calibration 1.
6 Checking and Adjusting Adjusting the calibration 1. Press [MENU] and [7]. The calibration screen appears. 2. The Focus 4 total station has two-axis level compensation. Take an F1 measurement to a target on the horizon. Press [ENT]. The calibration fields for F1 are: VA1 Face-1 vertical angle (tilt-off value) HA1 Face-1 horizontal angle (tilt-off value) X1 Face-1 X-axis tilt value Y1 Face-1 Y-axis tilt value The vertical angle is shown in the V0 dir= Horiz setting.
Checking and Adjusting 6 The instrument constant The instrument constant is a numerical value used to automatically correct for the displacement between the mechanical and electrical centers when measuring distances. The instrument constant is set at the factory. However, to ensure the highest operational accuracy, we recommend that you check the instrument constant several times a year. The following figure shows the setup to check the instrument constant.
6 Checking and Adjusting Checking the laser pointer The Focus 4 total station uses a red laser beam to a laser pointer. The laser pointer is coaxial with the line of sight of the telescope. If the instrument is well adjusted, the red laser pointer coincides with the line of sight. External influences such as shock or large temperature fluctuations can displace the red laser pointer relative to the line of sight.
CHAPTER 7 Transferring Coordinate Data Transferring coordinate data to the total station Transferring coordinate data from the total station 7 The Focus 4 uses lists of coordinate data. This chapter describes how to transfer data between the Focus 4 total station and the office computer.
7 Transferring Coordinate Data Transferring coordinate data to the total station Settings To configure the transmission speed and other settings, press [MENU] and then select Settings / Comm. See also Communications, page 99.
