Spectra Precision Focus 4 Total Station User Guide 25 2 Setting up the Instrument Calibration button “Calibration on” light (1) Top edge of case Power jack Charge light (2) Charge light (1) “Calibration on” light (2) 5 V, 4 A Battery slot 1 Battery slot 2 Applying power Plug in the charger to the supplied AC adapter to turn the unit on. The power input must be 5 V with at least 4 A of current capability. Each battery may take up to 2 A while charging. Charging the battery Slide a battery into either battery slot to begin charging. The adjacent charge indicator will illuminate yellow when charging is in progress. The charge indicator will change to green when charging is complete. Take note of the following: 26 • Charger slots are completely independent so a battery may be inserted regardless of what is occurring in the other battery slot. • Charging may take 2-4 hours if the battery was normally discharged. • Charging may take up to 5 hours with a completely drained battery which has been stored for several months without use. • If the charge indicator(s) are blinking, there is a problem with the battery or with the charger. Spectra Precision Focus 4 Total Station User Guide 2 Setting up the Instrument • Lithium-ion batteries should not be charged above 40 °C to 45 °C (104 °F to 113 °F). A blinking charge light may mean that the batteries are too hot for charging. Charging will resume after the batteries cool down. Conditioning / calibrating a battery You must calibrate the battery (“condition”) once every 6 months or more often if required. Calibration ensures that the reported remaining battery charge is accurate. To start calibrating a battery, hold down the calibration button on the unit and then insert a battery. Only the battery that was inserted while the button is pressed begins calibration. During battery calibration, the battery will be charged, discharged completely, and then recharged again. Calibration should complete in approximately 17 hours. Do not cover the charger vents during a calibration cycle. • The blue calibration indicator light(s) blink slowly (on 1.5 sec, off 2 sec) while calibration is in progress. The charge light(s) may be on or off during the calibration cycle if the case temperature does not get too high. • When a calibration cycle is completed, the calibration light stops blinking but remains on until the corresponding battery is removed. • Case temperature: – The temperature of the bottom case may continue to climb to approximately 43 °C before temperature regulation is enabled to keep the case from becoming warmer. As the battery voltage drops, the case cools down and the automatic temperature limiting is no longer necessary. This minimizes the time required to discharge a battery. – If the case temperature continues to become too hot internally, even after temperature regulation is enabled, there is a secondary failsafe that aborts the calibration completely. If an abort occurs, the calibration light(s) blink rapidly and battery charging is re-enabled.

Aim the telescope at the target image. b. Rotate the focusing ring until the target image is in sharp focus on the reticle cross-hairs. c. Move your eye vertically and laterally to check whether the target image moves relative to the reticle cross-hairs. – If the target image does not move, there is no parallax. – If the target image does move, rotate the telescope focusing ring and repeat Step 2c. Rotate the tangent screw. The final turn of the tangent screw should be in a clockwise direction, to align the target accurately on the center cross-hairs. Spectra Precision Focus 4 Total Station User Guide Setting up the Instrument Setting the measurement mode and preparing the target The Focus 4 total station has two measurement modes: Prism mode (Prism) and Reflectorless mode (N-Prism). To change the mode at any time from any observation screen, hold down [MSR1] or [MSR2]. Set the measurement mode depending on the target that you want to measure, as shown here. Target Target settings Prism, reflector sheet Prism mode Other, reflective materials Reflectorless mode In some cases, you can measure to another target that is not appropriate to the set measurement mode. Note – The Focus 4 total station is Laser Class 1 in the measurement function, and Laser Class 2 in the Laser Pointer function. Do not sight the prism when the Laser Pointer is on. Measurement with a prism As the Focus 4 total station is extremely sensitive, multiple reflections on the prism surface can sometimes cause a significant loss in accuracy. To maintain the accuracy of your measurements: • Use a prism with thin edges. Thin edges Do not use a prism with scratches, a dirty surface, a chipped center, or thick edges. Chipped center Thick edges Spectra Precision Focus 4 Total Station User Guide 33 2 Setting up the Instrument • When measuring a short distance, incline the prism slightly so that the EDM can ignore unnecessary reflections on the prism surface, as shown below. ✓ • Not completely square to the sighting axis ✕ Completely square to the sighting axis Hold the prism securely in place and do not move while taking measurements. In Prism mode, 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. Even if you start a measurement, measured values are not displayed. To measure less reflective objects, use the N-Prism (Reflectorless) mode. Measurement in reflectorless (N-Prism) mode The Focus 4 total station enables reflectorless measurements up to 300 m (984 feet). The intensity of the reflection from the target determines the distance the Focus 4 total station 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 less-reflective targets may not be measured. The following table describes some examples of targets and approximate measuring distances: Target You can measure approximately... Traffic signs, reflectors 500 meters (1640 feet) Paper (white), veneer (new) 300 meters (990 feet) wall (brightly painted), brick 100 to 200 meters (330 to 660 feet) Measurable distances may be shorter or measurement intervals may be longer if either of the following conditions apply: • the angle of the laser against the target is small • the surface of the target is wet In direct sunlight, the measurable distance may be shorter. In this case, try to throw a shadow on the target. Targets with completely flat surfaces, such as mirrors, cannot be measured unless the beam and the target are perpendicular to each other. 34 Spectra Precision Focus 4 Total Station User Guide Setting up the Instrument Make sure there are no obstacles between the instrument and the target when taking measurements. When you need to take measurements across a road or a place where vehicles or other objects are frequently moving, take several measurements to a target for the best result. Viewing and changing the measurement settings Hold down [MSR1] or [MSR2] for one second. • To move the cursor between the fields, press [^] or [v]. • To change the value in the selected field, press [<] or [>]. The available values are: Field Values Target Prism mode N-Prism mode Constant (prism constant) -999 mm through 999 mm Mode Precise Normal Track Track (continuous MSR) ON Track (continuous MSR) OFF Target field If the measurement is started with the Target field set to Prism mode, there is a dash in front of the prism constant, for example –18 mm . If the measurement is started with the Target field set to N-Prism (Reflectorless) mode, there is square bracket in front of the prism constant, for example ]18 mm. The displayed symbol will continuously move from left to right over the prism constant in the display. Prism constant The factory default of the prism constant value of the Focus 4 total station is -30 mm. Change the prism constant to match the constant value of the prism you are using. Once you have set up the instrument, you can turn on the Focus 4 total station, change the instrument settings, and start a job. See also page 37.
