  • Page 17 ‘x’ axis and then to exit. Function setup The function setup allows you to scroll through all the different function on the NMS 800 and activate them within the DRO. To scroll through the different setting press the key.
  • Page 18 Setting up the unit Digital type setup The digital type setting is a very important setting to tell the NMS 800 which type of encoder your using with your machinery. There are 4 options to use with the NMS 800: (These apply if more than one axes are digital) This shows that the DRO is for: Rotary decimal.
  • Page 19 When this setting is enabled, the NMS 800 will check for the different signals required. If the signal retrieved is an illegal signal, the DRO will return with SIG FAIL as shown in the table below. If a signal comes back and is correct, the DRO will continue as normal.

  • Page 22 AWAITING ALEX TO EXPLAIN Summing Setup The summing setting on the NMS 800 allows your to activate whether the two axes, or planes, that you have selected with the Plane setting show as one unit on the DRO screen. Press the axis select key next to the axis to cycle through the options This shows the summing feature is activated and will show the total of the axes.
  • Page 23 The first step in determining the source of error is to check the DRO system. To do this compare the movement of the Newall reader head to the position reading shown on the display. A high accuracy standard, such as a laser interferometer is required. A dial indicator can be used to check short distances, but a laser provides the best results.

  • Page 24: Error Compensation

    To check the accuracy of the DRO system: 1. Place the target of the laser or the needle of the dial indicator directly on the Newall reader head. It is absolutely critical that the readings are taken directly from the Newall reader head. If a dial indicator must be used, be sure that the needle of the indicator is perpendicular to the reader head and not angled.

    Setting up the unit Linear Error Compensation In this mode, a single constant correction factor is applied for each axis for all displayed measurements. Calculate the correction factor, and specify it in parts per million (ppm). When following the procedure ensure that a stepped standard is used, and approach each edge from the same direction;...
  • Page 26 Setting up the unit Teach Mode Teach mode is an easier way of calculating linear errors by using the NMS800 to automatically calculate the error.

  • Page 33 Digifind / reference function The NMS800 comes equipped with Digifind, a feature unique to Newall digital readout products. Digifind eliminates the risk of losing position and datum Set-Up. With Digifind, precise Set-Up of a work-piece is carried out only one time.
  • Page 34 Standard functions Sub datums / memory The NMS800 can store up to 200 SDM (Sub-Datum) positions, or machining steps into the memory. Using SDM allows the operator to work to zero by calling up stored dimensions, instead of “working up” to drawing dimensions. This eliminates the need to constantly refer to the drawing, and reduces the possibility of scrapping parts due to misread dimensions.
