Page 4: Description
[ DESCRIPTION ] （1） Display Display shows angle reading, battery status, and communication status. Angle The displayed angle can be switched between units of mm/m, or DEG （°） using the Units Switch on the front panel. When displaying units as DEG （°）, the leading 0 in front of the decimal point is not shown on the display in order to differentiate from display of mm/m. - Page 5 （２） Power Switch Unit is ready for use about 5 sec. after being switched ON. If the Sensor is not connected the display panel will not display a valid reading. 0-Cal and 1/2-Cal settings are not stored when power is turned off; when power is turned back on the reference point will need to be reset.
- Page 6 （５） 0-Cal, 1/2-Cal Switch 0-Cal Side When pressed in this direction, t he displayed measurement is set to zero. Switch requires deliberate press of about 1 sec. 1/2-Cal Side When pressed in this direction, the displayed reading is divided by 2. Value is changed when released.

Page 9: Measurement Range And Zero Point
[ 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 Sensor is limited by the range of the internal variable measured by the device. - Page 10 0-Cal, 1/2-Cal operations have not been performed. ◎ （Zero reference point for displayed value is same as internal reference.） Output from Sensor Display Zero Measurement Range ◎ Reference point moved 0.1 mm/m using the 0-Cal, 1/2-Cal operations. (For example, initial reading was 0.1 mm/m when 0-Cal is performed, or 0.20 mm/m before 1/2-Cal is performed.) Output from Sensor Display Zero...

Page 11: How To Use
[ HOW TO USE ] The Digital Sensor Unit is a precision instrument. Please handle with care and avoid any shock or mishandling. Please also handle the Display Unit with care and protect from rough handling. Connect the Display Unit to the Senor Unit using the connection cable (DL-P1). Before use, wipe the gauge base and the surface of object to be measured using a soft cloth or lens cloth moistened with mineral spirits or alcohol to remove any grease and contamination. - Page 12 When the Gauge is viewed with the data connector 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 "‒"...

Page 13: Zero-Point Setting
[ ZERO-POINT SETTING ] The Sensor does not have a preset absolute zero-point. When the Display is first turned on, a reading of zero 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 Display is switched on. - Page 14 ≪ 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.

Page 15: Leveling A Surface
[ LEVELING A SURFACE ] Leveling in one direction. （ １ ） Place the Sensor on the surface, and once the display has stabilized (while also checking bubble tube level reading.) Press the 0-Cal Switch to zero the reading. （ ２ ） Rotate the Sensor 180° in the same location on the surface. Check the bubble tube level -- it should read the same. - Page 16 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.

Page 19: Output Signal
[ Output Signal ] Displayed measurement value and units are output on the Data Out Jack. The signal is RS-232C compatible so can be connected to any computer or printer with an RS-232C port available. Signal is also used to connect to another DL-D3 when connecting multiple systems. Use an audio type mini-plug for connecting cable to Data Out Jack. - Page 20 （△symbol = space） Output units of mm/m 〃 〃 Output units of DEG（°） 〃 〃 Error output 〃 Signal output is controlled by the CTS signal. CTS tells the system when to transmit, or not to transmit data. If the Data Out Switch is set to “TERMINAL”. For CTS level “high”, measurement data is sent on TD with each data update..

Page 23: Shipping
[ SHIPPING ] The Sensor Unit 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 during shipping. Hand Carrying Always transport in supplied case. Transport in upright position and not on side or upside down. -
