    2.1 Mounting Select the location of the DP8 with due regard of safety and ease of operation. Keep it clear of moving parts and coolant spray. Ensure that the natural ventilation around the digital sending unit (DSU) is not restricted.
  • Page 5 An optional bracket (Part No 600-65590) is available to facilitate the mounting of the DSU directly to the keypad/display. This assembly can be mounted using the standard M10 stud, the swivel mount assembly (Part No 294-37740), the DP8 mounting arm (Part No 294-40050) . The last three items are optional and are detailed on the price list.

    If the machine has moved beyond 0.2500" (6mm) - Spherosyn [0.1000" (2.5mm) - Microsyn], Digifind allows a quick means to find the datum if lost. The DP8 will maintain the position for at least 30 days, the life of the battery back-up.

  • Page 22: Sub Datums (Sdm)

    The DP8 can store up to 199 SDM (Sub-Datum) positions, or machining steps, in non-volatile memory. The positions remain in memory even if the power has been turned off. Using SDM allows the operator to work to zero by calling up stored dimensions, instead of "working up" to print dimensions.
  • Page 23 Alternatively, use the [SDM] key to select a new SDM. NOTE: If the next move is Incremental, move to the zero position, select a new SDM number, and store the position with [SDM ZERO] 0.0000 To exit SDM function, select [ABS/INC]. 0.0000 Newall Measurement Systems...
