2.2. Battery and Charger Installing / Replacing Battery ①With the power off, pinch the clips on either side of the battery cover inward with your thumb and forefinger to unlock it, then gently pull the battery cover outward. ②Remove the battery from the battery cover. ③Make sure the battery electrodes are facing outwards and the electrodes are on top, and place the new battery into the battery cover. You will hear a clicking sound when the battery is fully inserted.
and hear a click sound to indicate that the placement is in place, at this time the battery cover should be flush with the side cover. Please use the charger and battery from STONEX. Store, use and charge at the specified temperature conditions, taking care to avoid contact with liquids. Charging ① Remove the charger and cable from the transport case, insert the C8 plug into the charger's corresponding socket for proper connection.
Batteries must be charged before first use. For new batteries or batteries that have been stored for a long time (e.g. more than 3 months), a complete charge/discharge operation can effectively improve battery performance. It is normal for the temperature of the battery and charger to rise during the charging process. If the temperature is too high, the charger will automatically suspend charging the battery. Battery operating temperature range: -10℃ to +50℃.
Ensure that the battery is charged and properly installed as required 2.4. Setting / Leveling up and Centring Setting up the Tripod and Instrument ① Adjust the tripod's three legs to nearly equal lengths that meet the height requirements for comfortable measurement. ② Position the tripod over the station point.
formed by the toes is close to the station point, and the tripod plate is nearly horizontal. ③ Take out the instrument and make sure that the instrument and its tribrach are firmly connected. Place the instrument onto the top plate of the tripod, fix the instrument with one hand, align the central knob of the tripod with the center hole of the tribrach with the other hand and tighten it. ④ Gently push the tribrach to make sure it is securely attached to the tripod plate.
status of tilt compensation, 2-Axes/ 1Axis/ off. 〈X〉: Indicates the tilt angle of the SA in the X direction, backward positive forward negative. 〈Y〉: Indicates the tilt angle of the SA in the Y direction, right positive left negative. 〈 〉: Indicates the brightness level of the plummet laser. Press [ ] / [ ] can adjust the levels with 0-4. 0 means off. [F1]【OFF】: Switch off tilt compensator and exit.
until the laser spot is precisely aligned with the station point, and then tighten the central knob. ⑥ Repeat steps ④ and ⑤ until the required accuracy of leveling and centering is achieved. If you can't level the instrument by the tubular level, please calibrate the tubular level. Avoid looking directly at the laser or its strong reflective light. Under different lighting and ground conditions, the plummet laser spot on the ground may be too bright or too dark to affect centring judgments.
When the function of 〈2-Axes〉in {level & plummet} is switched on, the instrument can automatically correct the error caused by the SA tilt, i.e., it can compensate the VA/HA automatically. The SA tilt of the instrument is the angle between the direction of the SA and the direction of the zenith (plumbing), which can be decomposed into two rectangular components, i.e., the X and Y direction tilt angle.
The tilt compensation function can be set in either {Level & Plummet} or {Setting} - {Angle Setting}. To avoid accidental tilting of the instrument which may affect the measurement accuracy, it is recommended that the user always switch on the dual-axis compensation function during normal operation. If the instrument is set up on an unstable base (e.g. on a shaking platform, ship, etc.), tilt compensation should be switched off. This avoids unexpected error messages and interrupting the measuring process.

8.1. About Calibration Some error checking and calibration operations can be carried out by the user in the field by running calibration procedures. These procedures need to be carried out carefully and correctly. The detailed procedure is described in the following sections. The instrument is factory calibrated to exacting specifications, but rapid temperature changes, vibrations or impacts may cause unexpected deviations and a reduction in the accuracy.
8.2. HZ-collimation and V-index HZ-collimation The HZ-collimation (C) is an error due to the fact that the CA of the instrument is not perpendicular to the TA. In the plane formed by the CA and the TA, the angle between the perpendicular line of the TA through the centre of the instrument and the CA is the HZ-collimation Error (C). Determine the HZ-collimation: ①Set up the tripod and instrument stable. ② Power on the instrument.
V-index When the VA (Zenith 0) is 90°0′0″, ideally the CA should be precisely perpendicular to the SA. And the actual deviation that exists is the V-index (i). Determine the HZ-collimation: ①Set up the tripod and instrument stable. ② Power on the instrument. Precisely level the instrument under the electronic level indication of {level & Plummet}. ③In face I, accurately aim at a target about 100m away whose height was similar as the instrument. Record the VAL.
8.3. Program Calibration The built-in calibration program can calibrate the following instrument error: ◼ Hz-collimation ◼ V-index ◼ Zero error of the tilt compansator While calibrating the V-index, the instrument will simultaneously calibrate the Zero error. Operation Interface ① In the measurement interface, press [M] to enter {Main Menu}. ② Use the navigation keys to select 〈5.Calib〉and press [ENT], or simply press the numeric key [5] to enter {Calibration}.
minutes. During the whole procedure the instrument must be protected from direct sunlight which can cause overheating on one side of the instrument. The procedure for calibrating the HA-colimation and the V-index is the same and requires accurate double-faced observation. During the calibration， the instrument interfaces give clear operating instructions that the user can follow to complete the operation. Calibration Procedure: ① Set up the tripod and instrument stable. ② Power on the instrument.
In the last calculated value interface, Press [ESC] can quit the calibraton and retain the old parameters. During the calibration process, the program may pop up a message warning if the operation does not comply with the specifications. Item Description 〈VA not suitable for calibration〉 The VA was too far off 90°, or aiming deviation was too big in face II. 〈HA not suitable for calibration〉 Aiming deviation was too big in face II.
original set value. 8.4. Mechanical Check and Adjust Check and Adjust the Instrument Tublar Level and Tribrach Circular Level ①Set up the tripod and instrument stable. ②Power on the instrument. Precisely level the instrument under the electronic level indication of {level & Plummet}. ③The bubbles of the tublar level and the circular level should stop right at the centre. ④If not, use the adjusting pin to adjust related screws till the bubbles was at the center.
④Slowly rotate the instrument horizontally one turn, observe the displacement of the centre of the laser spot. ⑤If the displacement is in a clear circular motion and the diameter of the track circle exceeds 3 mm, a calibration is required. The laser plummet calibration needs to be carried out by an authorised service centre.
