Set the tripod and fix the metal shoes firmly into the ground so that the tripod head is as level as possible, and the Tripod head coincides with the station on the ground. Fasten the leg screws. ................ If the tripod head is mis-leveled by the action of fixing the metal shoes into the ground, correct the level by extending or retracting each leg of the tripod... 3 PREPARATION FOR SURVEYING 3-2 Laser plummet Laser plummet model The laser plummet is not set to be ON at factory shipping.

Please note that the movement of the vial becomes opposite direction if it sees at the position of ..Right circle position". .. When instrument is within the tilt compensation range, length and sidewise..3', “ON” is displayed at the right screen, “ OVER” is displayed beyond the limits of range and “NIL” is displayed at no compensation setting. .. With command No "520" or "Initial setting 2", when the [TILT DISP] is selected as ON, the [F1 -TILT] of the vial screen becomes effective. The Vial til

• If water should happen to splash on the instrument or the battery, wipe it off immediately and allow it to dry in a dry location. Do not put the instrument in the case until it is completely dry as this may result in damage to the instrument. • Turn off the power when removing the battery from the instrument as removing the battery while the power is still on may result in damage to the instrument. • The battery mark displayed on the instrument is only an estimate of remaining battery power an

However, there is a possibility including some errors in this case, so be sure to select the reflectorless mode. • The target constant should be correctly selected and confirmed in case that the reflector sheet is used at the prism mode and the prism is used at the reflector sheet mode. 6.2 Distance measurement H.angle H.dst.
