General This instrument grade, high precision electronic level determines inclination angle by using a microcomputer to measure the displacement of a pendulum. Pendulum position is converted to an electric signal and the measured angle is displayed on the digital display in units of mm/m of inclination, or degrees ( °...

4 Display ( Front / Rear ) The displays show angle measurements, battery status, and communication status. ■Angle The displayed angle can be switched between units of mm/m, or degrees ( ° ) using the Units Switch. When displaying units as degrees, the leading 0 in front of the decimal point is not shown on the display in order to differentiate from display of mm/m.

Variation of measuring range due to movement of reference point ■ The instrument can be set to display a reference point of "0" at any angle using the 0-Cal and 1/2-Cal buttons. However, the measuring range of the instrument is limited by the range of the internal variable measured by the device.
Page 35
■ The following diagrams represent the two ranges for various conditions. The upper line in each diagram, marked "I ", shows the internal measurement range, and the lower line, marked "D", shows the value displayed and output externally. ( All values shown in units of mm/m. ) ◎...
How to use This is a precision instrument; please handle with care and avoid any shock or mishandling. ( 1 ) Before use, wipe the instrument base and the surface to be measured using a soft cloth or lens cloth moistened with white cleaner or alcohol to remove any grease and contamination.

When viewed from the front ( with the display panel on the right side, ) if the right side is elevated the angle reading will be an increasing positive number. If the angle is out of range, an error message will be displayed. For negative angles, a "...
Zero-point setting ① Setting zero-point for comparative measurements ( 1 ) Place the instrument on the reference surface. ( 2 ) When the display has settled, press the 0-Cal button to set the display to zero. A relative zero-point has now been set for use in comparative angle measurements.
Page 39
< 0-Cal, 1/2-Cal Operation > The zero-point reference is set without an absolute reference by using the direction of Earth's gravity as a reference. This can be understood from the following procedure. Suppose a slope having an angle θ with respect to the horizontal plane. Place on that slope a board with a weight suspended on thread.
Leveling ■Leveling in one direction ( 1 ) Place the instrument on the surface, note the position of the air bubble on the Secondary Bubble Level, and press the 0-Cal button to zero the reading. ( 2 ) Rotate the instrument 180° in the same spot on the surface and confirm that the bubble position on the Secondary Level has not changed, then press the 1/2-Cal button to halve the reading.
Page 41
■Leveling in two directions (X, Y direction) ( 1 ) For one direction ( for example the X-direction, ) follow the above procedure for 「■Leveling in one direction」 ( P39 ) . ( 2 ) Repeat the procedure for the other direction ( the Y-direction ) . ( 3 ) When adjusting in one direction, it is possible that the perpendicular direction will be affected and no longer level.
Output signal The measurement value and units can be read off the Data Out Jack on the rear of the instrument. The signal is RS-232C compatible. Use an audio type mini-plug for connecting cable to Data Out Jack. ( Output ) Transmitted Data ( Input ) Clear to Send...

Transportation method This is a precision instrument; when carried or shipped, care must be taken to avoid damage. Please be careful not so subject instrument to shock, vibration, or excessive forces when shipped. ■Hand Carrying ・Always transport in supplied case. ・Transport in upright position and not on side or upside down.
Precautions ・This is a precision instrument, handle with care. While in use and during transport protect from excessive shock, vibration, or excessive force to the main body or to the measuring surfaces. ・The measuring surfaces on the bottom and side are critical components for accurate measurements, use care to protect from corrosion.
