2, Niigata seiki LEVELNIC [ INTRODUCTION ] This high precision microcomputer controlled level measures angle by measuring the displacement of a pendulum. Displacement is converted to an electronic signal and is displayed as mm/m of inclination on the digital display. [ FEATURES ] Capacitive sensor for high sensitivity and stable output.◎ Can measure a wide range of slope angles compared to a bubble (or "spirit") l…

4, （1） Display Display shows angle measurements, battery status, and communication status. Angle The angle is displayed in units of mm/m. If the angle exceeds the measurement range, an error message is displayed. For a positive out-of-range error, "EEE" is displayed, and for a negative out-of- range error, "－EEE" is shown. The "E" on the elevated side will blink. When th…

5, （4） 1/2-Cal / Output Signal Button Button function is set by the Function Select Switch to work as either 1/2- Cal Button, or Output Signal Button. 1/2-Cal Button Press the 1/2-Cal button to divide the displayed reading by 2. Value is changed when the 1/2-Cal button is released. Button requires deliberate press of about 1 sec. （Button can not be used during error display.） Output Signal Button Press the Output Signal Button to output…

7, [ Measurement Range and Zero-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. (This value can be seen when power is *rst turned ON, before changing the reference point.) Instrument does not have an internal reference to true horizon…

9, Niigata seiki LEVELNIC [ HOW TO USE ] This is a precision instrument. Please handle with care and avoid any shock or mishandling. Before use, wipe the instrument base and the surface to be measured using a soft cloth or lens cloth moistened with mineral spirits or alcohol to remove any grease and contamination. Place the instrument on the surface to be measured. Turn on the instrument using the…

10, When viewed from the front (with the display 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 "‒" sign is also shown. In the error message, the "E" on the elevated side will also blink to indicate the direction of the out-of-range error. The gauge will display the angle of inclination as mm/m, which is the elevation …
-
11, [ ZERO-POINT SETTING ] The instrument does not have a preset absolute zero-point. When *rst turned on, a reading of zero （ the internal value ） will not necessarily indicate that the gauge is at true horizontal position. If a zero-point is required it must be set each time the instrument is switched on. In this way, calibration error is eliminated and the zero-point is set accurately each time. Setting the zero-point to true horizo…
-
12, ≪ 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. As seen in the diagram below, the weight will move toward side A of the board at an angle θ from the line perpendicular to the slope. Wh…

13, Niigata seiki LEVELNIC [ LEVELING A SURFACE ] Leveling in one direction. （１） Place the instrument on the surface, and once the display has stabilized press the 0-Cal Button. （2 ） Rotate the instrument 180° in the same location on the surface, and once the display has stabilized press the 1/2-Cal Button. （3） Adjust the tilt of the surface to make the instrument's display read zero. （4 ） Rotate the instrument 180° again to con*r…
-
14, 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.” （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. It may be necessary to repeat steps (1), (2), several times to bring the two axis into level. When …

15, [ Output Signal ] The measurement value and units can be read off the Data Out Jack. The signal is RS-232 compatible so can be connected to any computer or printer with an RS-232 port available. Use an audio type mini-plug for connecting cable to Data Out Jack. （１） TD (Output) Transmitted Data （２） CTS (Input) Clear to Send （３） GND Ground Comm method Asynchronous Comm Control Hardware (CTS controlle…

16, Niigata seiki LEVELNIC Signal output is controlled by the CTS signal. CTS tells the system when to transmit, or not to transmit data. If the Function Select Switch is set to “1/2” For CTS level “high”, measurement data is sent on TD with each data update.. For CTS level “low”, or not connected, measurement data is not sent. If CTS is continuously “high”, measurement data will be sent continuously. If the Function Select Switch is set to “OUT” For CTS level “high”, measurement data is …

17, [ SHIPPING ] 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. When placing the gauge into the storage case, use care since the outer body is larger than the base and will get stuck. Shipping…
