Center crosshairs To sight the instrument: 1. Adjust the diopter: a. C Aim the telescope at a blank area, such as the sky or a piece of paper. WARNING – Never look at the sun through the telescope. If you do, you may damage or lose your eyesight. b. 2.
3 Preparation Setting the Measurement Mode and Preparing the Target The Focus 8 series has two measurement modes: Prism mode (Prism) and Reflectorless mode (N-Prism). These modes can be changed at any time by holding down the [MSR1] or [MSR2] key for one second. To set the measurement mode depending on the target you want to measure, see the following table.
3 Preparation To maintain the accuracy of your measurements: • B When measuring a short distance, incline the prism slightly so that the EDM can ignore unnecessary reflections on the prism surface, as shown below. Tip – Hold the prism securely in place and do not move while taking measurements. In Prism mode, in order to avoid false measurements on objects other than the prism or reflector-sheet, targets that are less reflective than the prism or reflector sheet are not measured.
3 Preparation Measurement in Reflectorless mode The intensity of the reflection from the target determines the distance the Focus 8 series can measure in this mode. The color and condition of the target surface also affect the measurable distance, even if the targeted objects are the same. Some lessreflective targets may not be measured. The following table describes some examples of targets and approximate measurable distances. Target You can measure approximately...
Preparation 3 Setting Up the Prism Reflector 1. Assemble the prism reflector as shown below. Target plate for single prism Target pole Height adjustment adapter is not used.

CHAPTER 5 Checking and Adjustment 5 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 Checking the Instrument Constant Checking the Laser Pointer Spectra Precision® Focus® 8 Series Total Station User Guide 41
5 Checking and Adjustment Adjusting the Electronic Level Adjustment of the electronic level is done by Zero point errors of vertical scale and horizontal angle corrections. For detailed instruction, please see page 43. Checking and Adjusting the Circular Level Once you have checked and adjusted the electronic level, check the circular level.
Checking and Adjustment 5 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, a cap needs to be removed. Zero Point Errors of Vertical Scale and Horizontal Angle Corrections Checking 1. Set up the instrument on the tripod. 2. Follow the leveling procedures described in Leveling, page 28. 3.
5 Checking and Adjustment To make a major adjustment to the trunnion axis error compensation, however, you can complete the second step that is described below and make three sets of observations. B Tip – To set the parameters for trunnion axis error compensation, establish two targets at a horizontal distance of at least 30 m from the instrument. The first target should be placed on the horizontal plane and the second should be more than 30° above the horizontal plane.
Checking and Adjustment 5 When you have taken the measurement, the message changes from DO NOT TOUCH! to Turn to F2. 2. Take an F2 measurement to the same target. Tap [OK]. VA2 HA2 X2 Y2 Face-2 vertical angle (tilt-off value) Face-2 horizontal angle (tilt-off value) Face-2 X axis tilt value Face-2 Y axis tilt value When the observation on F2 is completed, three parameters are displayed. 3. 4. Do one of the following: – To return to the first observation screen, tap [Redo].
5 Checking and Adjustment If the HA corr. setting is set to OFF, the ACH parameter is not applied to horizontal angle readings. If this setting is set to ON, both of the ACH and trunnion-axis parameters are applied to HA. If you do not complete the second step, the trunnion-axis parameter remains set to zero, and only the ACH parameter is applied. If ACV, ACH, X, or Y is out of range, OVER appears. Press any key to return to the first observation screen. Second step 46 1.
5 Checking and Adjustment The tolerance in angle reading to each direction is 10". To maintain the accuracy of the instrument, you must take shots with extreme care. If the dHA to the same direction is more than 10", an error message appears, and you must remeasure all three sets of points. After three sets of F1/F2 observations, the instrument calculates the trunnion axis parameter and the updated ACH (the average of each set). 3. 4.
5 Checking and Adjustment Checking 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 by the manufacturer before the instrument is shipped. However, to ensure the highest operational accuracy, we recommend that you check the instrument constant several times a year.
Checking and Adjustment 5 Checking the Laser Pointer The Focus 8 series 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.
